Jac Caglianone – 1B/LHP, Kansas City Royals
Performance/Scouting: Officially signed by the Kansas City Royals, Jac Caglianone, a dynamic two-way talent from the University of Florida. Jac is already turning heads during Spring Training. At 6’5”, Caglianone showcases elite-level power at the plate and impressive velocity on the mound. Hence, making him one of baseball’s most exciting dual-threat prospects. Scouts rave about his towering power potential (30+ HR capability) and a high-90s fastball that adds intrigue to his profile. The Royals plan to leverage his hitting primarily but haven’t ruled out using his arm, emphasizing versatility in his development.
Card Market Insights:
Since signing with Kansas City, Caglianone’s 2024 Bowman Chrome autograph cards have experienced a significant surge in the card market. His base autographs, initially trading around $150-$200, have seen a rapid uptick into the $300+ range within recent weeks. Color parallels, such as his Blue Refractor (/150) and Gold Refractor (/50), have jumped even more notably. As a result, reaching well above $700 to $1,500 in recent transactions. This surge is driven by his strong spring training performances, highlighted by viral home runs in Royals’ camp. Collectors are bullish on his upside, and current trends suggest further appreciation as he nears MLB readiness.
2025 Spring Highlight
Caglianone’s spring highlight remains his extraordinary 450-foot home run during Spring Breakout, solidifying his status as a must-watch prospect. His ongoing performances are significantly contributing to his hobby momentum, generating excitement among both Royals fans and collectors alike.
Roman Anthony – OF, Boston Red Sox
Performance/Scouting: Anthony is MLB’s No. 2 overall prospect (Top prospects on Spring Breakout rosters 2025) and arguably the top hitting prospect in baseball. As a 19-year-old in 2024 he reached Triple-A and held his own. Roman posted a 45.1% hard-hit rate in 30 games – among the best at that level (Spring Breakout prospects on the brink). He shows advanced plate discipline (walking as often as he struck out) and plus power to all fields. Red Sox officials say he’s “every bit a major-league ready player this Spring”. Consequently though, the crowded Boston outfield means they won’t rush him.
Card Market: Collectors are extremely bullish on Anthony. His 2023 Bowman Chrome 1st Prospect Autographs show explosive value. For example, a Blue Refractor (/150) PSA 10 sold for $2,130 in February 2025 on fanaticscollect. As the hobby anticipates his MLB debut (ETA mid-2025), Anthony’s cards are among the hottest in the prospect market. Some call it the rise of the “Roman Empire” in card collecting. If he’s called up in the summer, Topps will likely scramble to include him in late-2025 sets. Or save him as a headliner for 2026 Series 1.
2025 Spring Highlight
In minor-league camp and Spring Breakout games, Anthony has continued to flash elite hitting ability. Though no single highlight reel moment has gone viral yet, reports note he has consistently driven the ball with authority against advanced pitching. As a result, reinforcing why Boston fans are brimming with excitement for his call-up.
Max Clark – OF, Detroit Tigers
Performance/Scouting: Clark, the No. 6 prospect in MLB (Top prospects on Spring Breakout rosters 2025), was the third overall pick in 2023. Max is Detroit’s most heralded outfield prospect since Riley Greene. He’s a dynamic athlete with a sweet lefty swing, plus speed, and strong defense. Still just 19, Clark is likely a couple years away (ETA 2027) but already showed a mature approach. Tigers brass rave about his work ethic and all-around tools.
Card Market: As a top draft pick, Clark was one of the main chases in 2023 Bowman Draft. His 1st Bowman Chrome autos command hundreds of dollars on the secondary market. For instance, raw base autos have sold in the $200+ range (Max Clark #CDA-MC 2023 Bowman Draft Chrome Prospect ...). And colored refractors (like a Purple /250) have fetched around $400-$500 in graded form (2023 bowman draft draft picks & prospects autograph – PSA card). Collectors see him as a centerpiece of Detroit’s rebuild, so there’s strong long-term upside in his cards.
2025 Spring Highlight
Clark isn’t expected to reach MLB camp for a while, but in Tigers minor league spring games he’s turned heads with his polished hitting. A notable moment was a ringing opposite-field triple he hit in a scrimmage, showing off his speed and gap power. Detroit coaches have been impressed with how quickly he’s adjusting to pro pitching for such a young player.
Kristian Campbell – 2B/SS/OF, Boston Red Sox
Performance/Scouting: Campbell has risen rapidly to MLB’s No. 7 prospect status following a strong 2024 campaign. Known for his versatility, athleticism, and advanced contact skills, Campbell can handle multiple positions (2B, SS, OF) with ease. Although he experienced initial struggles in 2025 Spring Training, Boston management remains highly optimistic, emphasizing his quick bat, plus speed, and mature approach at the plate.
Card Market Insights:
Campbell’s official 2023 Bowman Draft Chrome Autograph cards have seen a substantial market surge recently. Initially undervalued compared to peers. His Bowman Chrome base autographs, previously trading around $40–$60, have increased sharply. Accordingly, now consistently fetching $120–$150 due to heightened collector interest. Color parallels such as Blue (/150) and Gold (/50) refractor autos have spiked considerably higher. With recent sales crossing the $500 mark, driven largely by speculation around Campbell’s potential MLB debut and his growing prospect pedigree.
2025 Spring Highlight
Though Campbell faced a slow start offensively, his standout defensive plays and overall athleticism impressed scouts and collectors. A remarkable defensive stop and strong spring showcase have reaffirmed belief in his talent. Hence, helping fuel his Bowman Chrome card price increases as anticipation builds for his eventual MLB debut.
2025 Spring Highlight
Caglianone’s spring highlight remains his extraordinary 450-foot home run during Spring Breakout, solidifying his status as a must-watch prospect. His ongoing performances are significantly contributing to his hobby momentum, generating excitement among both Royals fans and collectors alike.
Carson Williams – SS, Tampa Bay Rays
Performance/Scouting: Williams is MLB’s No. 9 prospect and is touted as perhaps the best defensive shortstop in the minors (Spring Breakout prospects 2025 MLB debuts). A 2021 first-rounder with a cannon arm and silky smooth glove. Offensively, Williams brings above-average power (he slugged 20 homers in High-A) but there are questions about his hit tool. He struck out ~28% of the time in 2024. He has yet to play a full season at Double-A. So the Rays will start him in Triple-A Durham (despite only a brief cameo there in 2023). If he can refine his plate approach and cut down the whiffs, Williams’ two-way upside is enormous. With no incumbent blocking his path in Tampa, a mid-2025 debut is realistic if he adjusts well.
Card Market: Rays prospects often garner hobby attention, and Williams is no exception. His 1st Bowman Chrome cards (2021 Bowman Draft) have been on the rise. Initially overshadowed by bigger 2021 names, his refractor autos now see increased demand as he nears the majors. For example, his Bowman Chrome base auto that once sold for ~$40-50 raw is now trending higher. And low-numbered parallels are drawing strong auction results (some colored autos in gem mint grades have topped a few hundred dollars). Collectors love his defense but generally big bat stats drive card prices. So a hot start in 2025 could really ignite his market.
2025 Spring Highlight
Williams made a web gem in a Spring game, diving to snare a line drive and showing why scouts rhapsodize about his glove. At the plate, he’s had an up-and-down spring. However, he did crush a long opposite-field homer in a March intra-squad game, hinting at the power he can bring if he makes contact. Rays coaches report that Carson is soaking up knowledge from major-league defenders in camp. As a result, positioning himself as the franchise’s shortstop of the future.
Travis Bazzana – 2B, Cleveland Guardians
Performance/Scouting: Bazzana, MLB’s No. 10 prospect, continues to impress with elite contact skills and exceptional plate discipline. He profiles as a classic leadoff hitter, showing advanced bat-to-ball ability and strong on-base capabilities. The Guardians remain confident in his potential, eyeing a possible MLB debut later in 2025.
Card Market Insights: Travis Bazzana’s 2024 Bowman Draft Chrome and Autograph cards have experienced significant market traction. His base autograph cards, initially debuting in the $50–$75 range, have surged recently, consistently fetching $125–$175 amid growing demand. Parallel refractor cards, notably Blue (/150) and Gold (/50), have climbed into the $400–$700 range due to increasing speculation about his near-term MLB impact. Collectors are bullish, anticipating further growth as Bazzana continues performing strongly in spring training and beyond.
2025 Spring Highlight
Bazzana stood out during Spring Breakout by consistently demonstrating his mature hitting approach. A memorable highlight was a lengthy 10-pitch at-bat culminating in a walk. Reinforcing his advanced skill set and driving additional excitement around his card market.
Marcelo Mayer – SS, Boston Red Sox
Performance/Scouting: Mayer is a familiar name – Boston’s former No. 1 pick and now MLB’s No. 12 overall prospect. A sweet-swinging lefty shortstop, Mayer hit .307/.370/.480 in Double-A in 2024 (Spring Breakout prospects on the brink of 2025 MLB debuts). Marcelo displaying the all-field hitting prowess that had some expecting him in Fenway by late 2024. A back injury (lumbar strain) shut him down in August, but he’s fully healthy now. Defensively, Mayer is solid at short, though Boston has contemplated if he might eventually slide to third. This given Trevor Story’s presence at SS and Devers(eBay)/Bregman at 3B. His path is a bit blocked. Regardless, Mayer’s combination of hit tool, power, and defensive ability give him All-Star upside. ETA is mid-to-late 2025 once an opening arises.
Card Market: Mayer’s cards have been popular since he was drafted in 2021. His 2021 Bowman Draft 1st Bowman(eBay) autographs were once among the most coveted of that class. Prices cooled slightly when newer prospects (and injuries) stole the spotlight, but they’re on the rise again after his strong Double-A showing. His refractor autos still trade for hundreds of dollars, and a low-numbered parallel can reach into four figures if graded. As a Red Sox blue-chip prospect, the hobby holds him in high regard. When he finally debuts, expect a Topps rookie card frenzy – Boston prospects tend to have large collector followings, and Mayer will be no different.
2025 Spring Highlight
Mayer has had a relatively quiet big-league camp, but in one Spring Training game he delivered a standout defensive sequence – making a tough backhand stop and starting an acrobatic 6-4-3 double play. At the plate, he stroked a few line-drive hits in Grapefruit League action, reminding everyone of his smooth swing. While he’ll start in Triple-A, coaches noted that “Marcelo looks ready for the next challenge” after observing his poise against MLB pitching.
Samuel Basallo – C/1B, Baltimore Orioles
Performance/Scouting: Basallo, MLB’s No. 13 prospect, is a 19-year-old power-hitting catcher (who also plays 1B) in the Orioles system. He was the youngest player in Triple-A at the end of 2024, so his modest numbers there can be forgiven. What stands out is his tremendous raw power – Basallo is built like a slugger and launches tape-measure shots in batting practice. Baltimore is working to refine his catching defense (receiving and blocking), and with Adley Rutschman entrenched in Baltimore, Basallo might split duties at 1B/DH when he comes up. His bat is his ticket – if he continues to mature as a hitter, he could be knocking on Camden Yards’ door by mid-summer (ETA June 2025) (Spring Breakout prospects on the brink of 2025 MLB debuts).
Card Market: Basallo’s first Bowman cards arrived in 2023, and he’s been on collectors’ radar as part of the Orioles’ impressive prospect wave. His 2023 Bowman Chrome prospect autographs (he has a 1st Bowman in that set) have been steadily rising in price. While catchers historically don’t get as much hobby love, Basallo’s youth and power are an exception – many view him as a bat-first prospect who just happens to catch. Recent sales of his autos reflect growing interest (for instance, his refractor autos have moved from the ~$50 range up into triple digits as he cracked the overall Top 15). If he continues to mash in Triple-A, expect further spikes.
2025 Spring Highlight
In Orioles camp, Basallo made noise with his light-tower power. During one intra-squad game, he blasted a homer that reportedly cleared the facility’s tall fence – a shot that had veteran observers buzzing. He also impressed O’s coaches with improved footwork behind the plate in drills. A fun moment: Basallo got to catch Grayson Rodriguez in a spring outing and handled the young ace’s nasty stuff well, a sign that his defense is coming along. Orioles fans see him as a potential middle-of-the-order force in the near future.
Bubba Chandler – RHP, Pittsburgh Pirates
Performance/Scouting: Chandler, MLB’s No. 15 prospect, is an athletic right-handed pitcher who originally was a two-way and two-sport star. He had a football scholarship offer as a QB). That athleticism shows on the mound – he has a live arm that touched 99.6 mph on his fastball this spring (Spring Breakout prospects on the brink of 2025 MLB debuts) and mixes in a sharp slider. After an uneven early 2024 in Double-A, Chandler dominated in Triple-A late in the year: 1.83 ERA with a 34% K-rate over his final outings (Spring Breakout prospects on the brink of 2025 MLB debuts). Pittsburgh considered him for an Opening Day rotation spot, and although a veteran signing bumped him to Triple-A, he’s poised to debut early (ETA May 2025) (Spring Breakout prospects on the brink of 2025 MLB debuts). Chandler could be one of the best pitching prospects to reach MLB this year if he continues this trend.
Card Market: Chandler’s prospect cards date back to 2021 (he had a Bowman Draft 1st as a two-way player). Initially, his hobby appeal was tied to the intrigue of him being a pitcher/shortstop combo. Now that he’s focusing on pitching – and succeeding – collectors are taking notice again. His 1st Bowman Chrome autos (especially colored refractors) are seeing renewed interest; for instance, his Blue Refractor autos that lingered around $30-40 raw a year ago have climbed as he’s neared the majors. Pirates fans and prospectors alike are buying in, expecting he could follow in Paul Skenes’ footsteps as the next big arm to hit Pittsburgh. Pitchers typically lag hitters in value, but a flamethrower with athletic pedigree like Chandler is bridging that gap.
2025 Spring Highlight
Chandler had a standout spring outing in which he struck out the side in one inning of a Grapefruit League game, reportedly fanning one batter with a 99 mph heater and another with a wicked slider. He also garnered attention by closing out last year’s 2024 prospect showcase game with a win. This spring, teammates joked that his former life as a shortstop shows up when he fields his position – he made a slick, barehanded grab of a weak grounder to throw a runner out. Chandler’s mix of showmanship and stuff made him a fan favorite in Pirates camp.
Noah Schultz – LHP, Chicago White Sox
Performance/Scouting: Schultz is MLB’s top left-handed pitching prospect (No. 16 overall). At 6’9”, the White Sox southpaw is an imposing presence on the mound, often drawing comps to Randy Johnson(eBay) for his build and release angle. He was dominant in Double-A last year with a 1.48 ERA and an excellent 4.8 K/BB ratio. The only concerns are experience and workload – he’s still very young (20) and has never thrown more than ~88 innings in a season. The Sox aren’t in a rush during a rebuild, but Schultz is so talented he might force their hand by late 2025. Chicago will likely monitor his innings, potentially capping him which could delay his debut (ETA August 2025). When he does arrive, he projects as a future ace with a high-90s sinker, sweeping slider, and improving changeup.
Card Market: Schultz’s prospect cards (he has a 2022 Bowman Draft 1st as a prep draftee) have attracted increasing attention, especially as he cracked several Top 100 lists as the highest-ranked lefty. Pitchers usually don’t top the hobby charts, but elite ones like Schultz are gaining traction (the hobby has warmed to arms in the wake of prospects like Yuri Pérez and Paul Skenes). His colored Bowman autos have been selling solidly – e.g. a Gold Wave auto /50 fetched a few hundred dollars recently. White Sox collectors see him as a potential cornerstone, and speculators like that he’s relatively affordable compared to similarly ranked hitters. If he continues to dominate the high minors in 2025, expect a bump in his card prices, especially ahead of an anticipated call-up.
2025 Spring Highlight
Schultz opened eyes in a minor-league spring game by striking out 5 of the 7 batters he faced, freezing some with a devastating slider. One AL scout in attendance reportedly quipped, “that’s the best lefty breaking ball I’ve seen in years” – high praise that reached social media and got collectors buzzing. Another moment that stood out: he effortlessly hit 98 mph on the radar gun in his first spring outing, showing no ill effects from last year’s workload. The White Sox have been cautious, but Schultz’s talent is on full display, reinforcing why he’s so highly regarded.
Sebastian Walcott – SS/3B, Texas Rangers
Performance/Scouting: At just 18 years old, Walcott is already the Rangers’ top prospect and ranks No. 17 overall in MLB. The Bahamas-born infielder is an athletic freak – 6’4” with lightning bat speed and terrific raw power. He impressed coaches as the youngest player in Texas’s big league camp this spring, more than holding his own against older competition (Spring Breakout rosters 2025). Walcott was reassigned to minors in mid-March to get regular at-bats, but not before leaving a strong impression with his mature approach and work ethic. Scouts think he could stick at shortstop for now, but he also saw time at third base. ETA is 2026 due to his youth, but his upside is off the charts (imagine a taller Alfonso Soriano-type skillset).
Card Market: Walcott’s cards became hot tickets as soon as they hit the market. His 2023 Bowman Chrome 1st prospect card is one of the headliners of that release, and his autographs are selling for hefty sums. For example, hobby buzz noted that a Red Refractor (/5) auto of Walcott was valued in the thousands (one such card appeared on Card Ladder’s tracker as a top Rangers prospect sale) (Texas Rangers Phenom Sebastian Walcott and Key Cards). His base autos are still relatively affordable compared to mega-prospects like Ethan Salas, but they’ve been steadily climbing. With the success of fellow Ranger prospect Wyatt Langford last year, Rangers fans are now scooping up Walcott as the next big thing. If he continues to wow in the minors at age 18, his market could explode even further.
2025 Spring Highlight
Walcott had several “wow” moments in camp. In one Rangers exhibition, he roped a double off the wall against an MLB veteran pitcher, showcasing his bat speed. In another workout, he impressed Corey Seager with a slick flip on a double-play turn. Perhaps the most memorable: during batting practice, Walcott launched a ball so far to left field that teammates jokingly asked if it landed in Oklahoma. It’s clear this kid has special talent, and his Spring Breakout appearances should only add to the growing legend.
