Aaron Holmes 
Paul Skenes dominated baseball in 2024. The young pitcher finished third in NL Cy Young voting and won Rookie of the Year honors. His success shows how new talent changes baseball’s competitive scene.
The 2025 MLB rookie class looks just as exciting. Japanese phenom Roki Sasaki leads the pack with his powerful 102.5 mph fastball. His 88-90 mph splitter generates an impressive 57% swing-and-miss rate. Dylan Crews adds another dimension to this talented group. He stole 37 bases at three different levels and led LSU to victory in the College World Series.
These rising stars could shape the 2025 season significantly. Their talent might determine playoff races, and they could follow Skenes’ path to become game-changers at baseball’s highest level.
College Stars to MLB Rookies: The Fast Track
MLB organizations now value the college baseball pipeline more than ever. College stars bring refined skills and game-ready approaches to the big leagues faster than their predecessors, which leads to quick success at the Major League level.
Dylan Crews: From College World Series to the Big Leagues
Dylan Crews shows us how quickly campus stars can become MLB rookies. The Nationals picked him second overall in the 2023 draft after he won both the 2023 College World Series and Golden Spikes Award at LSU. He made his MLB debut in August 2024, barely a year after draft day23.
Crews stands out because he has rare abilities. He’s one of just two hitters in the 2025 Prospect Handbook with five above-average or better tools23. His brief 31-game MLB stint showcased his elite speed – he stole 12 bases32 and recorded 3 Outs Above Average on defense32.
His early slash line (.218/.288/.353 with 3 homers) might not jump off the page33, but deeper numbers tell us more. A 44.7% hard-hit rate32 hints at serious power potential as he adapts to big-league pitching. He now stands as the life-blood of Washington’s rebuild alongside CJ Abrams and James Wood.
Matt Shaw: The Cubs’ Infield Solution
The Chicago Cubs found their answer at third base in Matt Shaw. The Maryland program’s highest-drafted player went 13th overall in 202323. Shaw’s college career shines bright – he won Big Ten Player of the Year, the Brooks Wallace Award for top collegiate shortstop, and earned Cape Cod League MVP honors in 202234.
Shaw moved through the minors like a rocket. He hit .284/.379/.488 with 21 home runs and 31 stolen bases between Double-A and Triple-A in 202435. This earned him an MLB roster spot for Opening Day 2025, when he debuted during the Tokyo Series in March34.
Though originally a shortstop, Shaw has adapted well to third base, filling a crucial gap in the Cubs’ infield. “Defensively is where I’ve grown the most,” Shaw said. “I feel really comfortable at third base, which is really exciting for me”35. His versatility and “average-to-above-average tools across the board”33 make him a valuable piece in Chicago’s balanced lineup.
Why College Rookies Often Adapt Faster
Numbers show college draftees reach the majors substantially quicker than high school picks. Research from 2000-2018 reveals college players taken in the top 20 picks needed 810 days to reach MLB. High school selections took 1,458 days – about two years longer36.
Several reasons explain this faster timeline:
- Advanced Development Environments: Elite college programs now use sophisticated analytics and hire former pro coaches, creating pro-style training environments37.
- Quality Competition: Players who face tough opponents in high-pressure games like the College World Series arrive better prepared for pro challenges38.
- Better Scouting Data: Teams now have complete batted-ball metrics and detailed video from college games. This helps them evaluate players more accurately and promote them more aggressively37.
- Faster Promotions: Teams quickly move college draftees to Double-A and Triple-A to test their skills against advanced competition37.
Notwithstanding that, college players face a tight window to prove themselves. Research suggests that college draftees who don’t reach the majors within three years likely won’t become solid regulars36.
Dylan Crews and Matt Shaw prove that the quick path from campus to the big leagues works. These polished prospects bring immediate value while still having room to grow at baseball’s highest level.
International Sensations Making Their MLB Debut
MLB rosters keep getting richer with international talent, and the 2025 season brings some of the brightest overseas stars ready to make their debuts. These players come with years of experience from leagues around the world and could make an immediate difference, though they face some tough challenges adjusting to American baseball.
Roki Sasaki: Japan’s Pitching Phenom Joins the Dodgers
Roki Sasaki stands out from other international prospects at just 23 years old. He’s ready for MLB right now, unlike most 16-17 year olds who usually headline these international classes9. His dominance in Japan’s Nippon Professional Baseball (NPB) earned him the top spot as MLB Pipeline’s #1 overall prospect for the 2025 season9.
The Dodgers got their man with a minor-league contract and a $6.5 million signing bonus in January 202539. They beat San Diego and Toronto to sign him39. Sasaki throws heat – his fastball hit 97 mph in his MLB debut40. He pairs that with a nasty splitter that leaves batters helpless when he gets it right.
But life in MLB hasn’t been easy for Sasaki. His first two starts showed some control problems – he walked 9 batters in just 4⅔ innings39. Dodgers manager Dave Roberts keeps it in perspective: “All he’s known is success… This is all a learning curve”40.
Hyeseong Kim: Korea’s Golden Glove Winner
Hyeseong Kim brings his defensive magic from Korea’s KBO, where he won four Gold Glove awards11. The Dodgers signed this smooth-fielding infielder to a three-year, $12.5 million deal in January 2025. The contract could grow to $22 million with options12.
Dodgers veteran shortstop Miguel Rojas can’t say enough good things about Kim: “He can be a Gold Glove Award winner, a Platinum Glove winner, at second base… The guy really makes the plays”11. Los Angeles wants to see what Kim can do all over the field – at center field, corner outfield spots, and third base12.
Kim’s biggest challenge lies at the plate. His .304 career KBO average came against pitchers throwing about 90 mph, which is 4 mph slower than MLB averages12. That’s why the Dodgers started him in Triple-A to help him develop13.
The Adjustment Period for International Rookies
International players face some unique hurdles in MLB:
- Performance Expectations vs. Development Needs: Teams must balance quick results with long-term growth, as we see with Sasaki’s early struggles and Kim’s Triple-A start.
- Technical Adjustments: Kim’s work with Dodgers hitting coaches shows how players often need to change their mechanics11.
- Cultural Transitions: Players must learn new languages and adapt to American life while playing baseball.
MLB has seen many international rookies succeed despite these challenges. Ichiro Suzuki (2001), Shohei Ohtani (2018), and Hideo Nomo (1995) all won Rookie of the Year awards after coming from professional leagues in their home countries2.
Looking at past success stories, Sasaki leads the pack as NL Rookie of the Year favorite with +200 odds2. This shows how the top MLB rookies often come from overseas, not just through the American system.
Comeback Stories: Top MLB Rookies Overcoming Adversity
Baseball stardom rarely follows a straight path. Many of baseball’s most promising MLB rookies hit major roadblocks before they make it to the majors. The 2025 season features several top prospects who fought through serious injuries and other obstacles to reach the big leagues.
Kumar Rocker: From Draft Controversy to MLB Debut
Kumar Rocker’s path to the majors had more twists than a breaking ball. He dominated at Vanderbilt and became the Mets’ 10th overall pick in 2021, but medical concerns kept him unsigned14. The Rangers believed in his potential and picked him third overall in 202215.
His professional career had barely started when he needed Tommy John surgery in May 202316. His hard work paid off as he returned to regular-season action in July 2024, about 14 months after surgery16.
The numbers spoke for themselves – Rocker posted a 1.96 ERA across three levels with an outstanding 11:1 strikeout-to-walk ratio16. His MLB debut in September 2024 showed his raw talent and post-injury challenges. His devastating slider generated 17 swings and misses15.
The Rangers see him as a key part of their 2025 rotation. He stands out as one of the top MLB rookies 2025 ready to make his mark over a full season.
Andrew Painter: Return from Tommy John Surgery
The Phillies’ best prospect Andrew Painter hasn’t played an official game since September 2022. He underwent Tommy John surgery in July 202354. His recovery should take 15-18 months4, which points to a mid-2025 MLB debut.
Painter’s comeback looks good. He hit 100 mph with his fastball in the Arizona Fall League and mixed in a hard high-80s slider5. He struggled with command – typical for pitchers after elbow surgery – but his 29-pitch outing marked a vital first step5.
Phillies ace Aaron Nola has helped the 21-year-old navigate his UCL recovery17. If his progress continues, Painter should join Philadelphia’s rotation by summer as one of the best MLB rookies in 2025.
Jasson Domínguez: Battling Through Injuries and Expectations
Yankees’ Jasson Domínguez gave fans a taste of his talent in 2023. He became the youngest Yankee since Mickey Mantle to hit a homer and steal a base in the same game18. But his promising start ended after just eight games due to a torn UCL in his right elbow18.
Doctors estimated a 9-10 month recovery after Tommy John surgery1819. His rehab went well until May 2024, when he started a 20-day assignment20. A new challenge emerged when he felt pain near his left oblique during a checked swing in June21.
These setbacks haven’t dimmed Domínguez’s star power among 2025 MLB rookies. He hit .356 with six homers in 23 minor league games in 202421. The Yankees still see him as their future center fielder – if he can stay healthy.
These comeback stories show that many MLB top rookies must overcome tough challenges before they can shine on baseball’s biggest stage.
Team Impact: How Rookies Will Shape the 2025 Playoff Race
Rookie talent often decides tight playoff races. First-year players now shape postseason results more than ever. The 2024 season showed this clearly when Milwaukee’s Jackson Chourio bounced back from early struggles. He posted an .883 OPS in the final four months and helped the Brewers “run away with the NL Central”8.
AL East: Rookies in Baseball’s Toughest Division
Baseball’s most competitive division, the AL East, has an impressive rookie class that could make all the difference in 2025. The Yankees believe switch-hitting Jasson Domínguez will be their solution in left field. His strong but brief 2023 debut ended early due to Tommy John surgery22. His mix of power and speed makes him a game-changer in their quest for a championship.
Boston has the division’s best prospect pipeline. Roman Anthony, ESPN’s #2 overall prospect, has a “power-and-patience approach” that seems “tailor-made for a big league outfield”23. On top of that, Kristian Campbell looks like “a prime candidate to win the American League Rookie of the Year Award”24.
The Rays keep their tradition of bringing up talented rookies with shortstop Carson Williams. His “combination of defense, power and athleticism gives him all-star upside”6. Baltimore’s Coby Mayo brings big power potential after he hit .592 in the minors last year7.
NL West: Can Dodgers Rookies Contribute to a Dynasty?
The Dodgers excel at using rookie talent during their dominant run. Their 2016 team got “15.4 wins from rookie players”25 despite having MLB’s biggest payroll. This shows how well they develop talent.
Roki Sasaki leads their 2025 rookie class as “the best pitching prospect in the world”23. Korean infielder Hyeseong Kim adds defensive excellence. Veteran Miguel Rojas believes Kim “can be a Gold Glove Award winner” at second base12.
Rebuilding Teams Banking on Rookie Production
Several rebuilding teams put their future hopes on rookie talent:
- Nationals: Dylan Crews and James Wood provide “exciting youngsters firmly in their 2025 plans”26
- Pirates: After Paul Skenes’ outstanding rookie season, Bubba Chandler brings “elite fastball and strong secondary stuff”24
- Athletics: Jacob Wilson looks set as their everyday shortstop after hitting a minor league-best .433 across three levels23
These rookie contributors will shape the 2025 pennant races. This matters most for teams like the Phillies whose “only primary goal for the 2025 season” is winning the World Series8.
The Next Generation: Comparing 2025 MLB Rookies to Established Stars
MLB teams often look at how new MLB rookies match up against proven stars. This helps set realistic expectations. These historical comparisons give us a better way to predict which young players might become the next big stars.
Who Could be the Next Paul Skenes?
Skenes has set the bar incredibly high for pitching prospects. His rookie numbers tell an amazing story – a 1.96 ERA and 11.5 strikeouts per nine innings, which ranks among the best rookie performances since 192027. His 214 ERA+ and 5.9 WAR28 proved he belonged at the highest level right away.
Jackson Jobe looks like the closest match among 2025 MLB rookies. He’s rated as the “best pitching prospect in baseball”1 and throws four different pitches. His arsenal includes “an elite changeup, one of the best in the minors”1. Jobe’s high-90s fastball and nasty off-speed pitches remind scouts of Skenes, though he still needs to work on his command.
Kumar Rocker offers another exciting comparison. His 2024 stats jump off the page – a 1.74 ERA with 61 strikeouts in just 41⅓ innings3. His slider gets batters to miss at an incredible “66% whiff rate”3, much like Skenes does with his devastating pitch mix.
Finding the Next Jackson Merrill
Merrill quickly became his team’s life-blood. He put up an .826 OPS with 24 home runs29 and won a Silver Slugger as a rookie. The team locked him up with a nine-year, $135 million extension29.
Dylan Crews shows similar traits as a five-tool player. Baseball’s #4 prospect3 combines blazing speed with unexpected power, just like Merrill. His defense stands out too – he’s already saved 3 runs above average in limited playing time3, which matches Merrill’s excellent outfield play.
Rookies with Multiple All-Star Potential
Jacob Wilson leads the pack of top MLB rookies 2025 who could become All-Stars. His minor league batting average of .40130 and projected 3.3 WAR3 suggest he’ll make an immediate splash. His “55 defense”1 at shortstop makes him even more valuable.
Roman Anthony – now baseball’s #1 prospect according to some experts31 – brings “potentially above average power”10 and “double-plus speed”1 that could earn him several All-Star nods. His minor league numbers (.294/.392/.501)10 show he can do it all at the plate.
Conclusion
The 2025 rookie class in baseball looks like one of the most talented groups we’ve seen in years. These young players come from all walks of life – college stars like Dylan Crews and international phenoms like Roki Sasaki. Each took a different path to the majors, but they all could change the game in big ways.
Without doubt, many of these rookies will boost their teams’ chances at October baseball. Players like Matt Shaw and Jasson Domínguez have already shown what they can do when the lights shine bright. On top of that, comeback stories like Kumar Rocker’s prove that tough times often create stronger players.
The 2025 season should bring plenty of thrills as these rookies find their footing in the big leagues. Not every prospect will match Paul Skenes’ quick rise to stardom, but this talented group will definitely make their presence felt. Fans will watch these players grow throughout the season, and their success might shake up MLB’s power balance for years to come.
