The 2025 fantasy baseball season is rapidly approaching, and fantasy managers are already on the hunt for the next wave of breakout stars.
Identifying players who can outperform their Average Draft Position (ADP) is crucial for gaining an edge in your league.
This article will delve into six rising stars poised for breakout performances in 2025. These players have the potential to significantly impact your fantasy team’s success.
Masyn Winn, the St. Louis Cardinals’ top shortstop prospect, is primed for a breakout in 2025. The Cardinals are in a rebuilding phase, aiming to create a more dynamic offense, and Winn could be a key contributor at the top of their lineup.
Elite Speed and Base-Stealing Potential
Winn is known for his elite speed, ranking in the 87th percentile in sprint speed. He stole 11 bases last season and has multiple 30+ stolen base seasons in the minors.
There’s a bold prediction that he will reach 30+ stolen bases in 2025, marking his first 20+ stolen base season in the majors.
Contact Skills and Lineup Position
His combination of speed and solid contact skills gives him the potential to bat in the top third of the lineup, where he can score runs and create havoc on the bases.
Despite not being a power hitter, Winn still managed to hit 15 home runs in 2024. His ability to consistently make contact and steal bases makes him a high-floor, low-risk fantasy asset in deeper leagues.
Currently, he is being drafted outside the top 150 overall and is the 17th shortstop being drafted, behind players like Xander Bogaerts, Xavier Edwards, and Bo Bichette.
Michael Toglia: Power Hitter in Coors Field
Michael Toglia is a popular breakout candidate for the 2025 season, and rightfully so. He has all the tools to be a major power hitter for the Colorado Rockies.
Power Metrics and Home Run Potential
Toglia has shown tremendous power throughout his minor league career, with 20 and 30+ home run seasons in 2022 and 2023. He ranks in the top 10% of the league in power metrics, including hard-hit rate and barrel rate.
His power profile is one of the best in Major League Baseball, making him a strong candidate to crush 35+ home runs this year.
Lineup Position and Fantasy Value
The Rockies are expected to give Toglia plenty of at-bats in the heart of the lineup, boosting his chances of driving in runs and scoring frequently.
He has already flexed his power muscle early in spring training with 2 home runs and 5 RBIs, putting up a 1.569 OPS in his first 8 spring at-bats.
Toglia is currently being drafted outside the top 150 picks and as the 20th first baseman, behind players like Jake Burger, Christian Walker, and Luis Arraez. He could be a great sleeper, capable of producing a 30 home run, 100 RBI season.

Jung Hoo Lee: Contact Hitter with Elite Plate Discipline
Jung Hoo Lee, the top international prospect out of South Korea, is ready to make an impact in 2025 after missing most of the 2024 season due to injury.
Contact Skills and On-Base Ability
Lee is a pure contact hitter with elite plate discipline, making solid contact consistently.
While he doesn’t offer the same power as other outfielders in his ADP range, he has had double-digit home run seasons, including a 23 home run season in 2022 in the KBO.
Lee brings a steady batting average and an ability to score runs, projecting to hit at the top of the San Francisco Giants’ lineup.
Fantasy Impact
Lee’s ability to make contact, generate hits, and get on base makes him an ideal target for managers in need of a batting average boost. While his power won’t win fantasy leagues, his contributions across multiple categories, including runs and steals, make him a prime breakout candidate for 2025.
Spencer Arrighetti: Next in Line for Astros’ Pitching Success
The Houston Astros have a history of developing successful pitchers, and Spencer Arrighetti looks like he could be the next breakout star in their rotation.
Strikeout Potential and Pitching Arsenal
Arrighetti boasts a powerful fastball, sharp slider, and promising changeup. His minor league numbers are impressive, with a 30% strikeout rate and four straight seasons of 100+ strikeouts.
After the All-Star break in 2024, he posted a 3.18 ERA, 1.17 WHIP, and 78 strikeouts over 65 innings.
Fantasy Value and Team Support
Arrighetti is expected to join the Astros’ rotation in 2025, benefiting from a team that excels in supporting pitchers.
Given his strikeout upside and ability to keep runners off the bases, Arrighetti could be a fantasy breakout in deeper leagues and a potential top-50 starting pitcher if he stays healthy.
Reese Olson: Rising Star in Tigers’ Rotation
Reese Olson is a rising star in the Detroit Tigers’ pitching rotation, set to make a significant jump in 2025.
Deceptive Stuff and Strikeout Upside
Olson is known for his deceptive stuff and plus-slider, showing great potential as a starting pitcher in the minors.
He has consistently posted high strikeout rates and low walk rates, while also limiting home runs. In 2024, he finished with a 3.5 ERA, 3.17 FIP, and 0.56 HR/9.
Fantasy Impact
Olson may not have the same name recognition as other top-tier starting pitchers, but his ability to keep hitters off balance and his strikeout potential make him an intriguing breakout candidate for 2025.
While playing for the Tigers might limit his win potential, his strikeout upside and ERA potential make him a solid addition to your fantasy rotation.
Tobias Myers: Underrated Pitching Prospect in Brewers’ System
Tobias Myers is one of the more underrated pitching prospects heading into 2025, with the potential to break out in the Milwaukee Brewers’ system.
Pitching Arsenal and Strikeout Potential
Myers boasts an excellent arsenal, including a fastball that can reach the mid-90s and a deceptive curveball. He is slated to be the Brewers’ SP2, making him a sneaky source of strikeouts with solid ratios.
Fantasy Value
Myers fits the mold for the Brewers’ next breakout pitcher in their rotation for 2025.
With a combination of strikeouts, low ERA, and WHIP, Myers is a pitcher who could outperform his ADP.
Currently being selected outside the top 300 overall and outside the top 100 pitchers, he has the upside to exceed expectations and be a great breakout candidate in 2025.
