Underrated Players Making an Impact in MLB: 2025 Edition

Part of what elevates a successful team is the emergence of players who exceed expectations set before the season. Moneyline examines the most underappreciated players for each MLB team in 2025. This exploration highlights young talents blossoming or veterans exceeding their historical performance. This analysis is crafted from a national perspective, acknowledging that dedicated fans may already recognize some of these names. However, for those looking to gain insight into players who may not receive widespread recognition, this investigation is insightful.
For the New York Yankees, Fernando Cruz has emerged as a significant contributor despite battling right shoulder inflammation that sidelined him for a portion of the season. Prior to his injury, he recorded a 2.66 ERA across 21 games, along with an impressive strikeout rate of 13.3 K/9 over 23.2 innings pitched. The Yankees acquired Cruz in a trade with the Cincinnati Reds during the offseason, and his performance thus far showcases the potential impact of this transaction.
José Caballero of the Tampa Bay Rays, while no stranger to success after leading the American League in stolen bases the previous season, has hit a positive stride in 2025. Having stolen 44 bases last year but also experiencing a high number of unsuccessful attempts, Caballero has improved his efficiency this season, successfully stealing 19 of 23 bases. Additionally, he has elevated his OPS from .630 to a commendable .735.
Addison Barger, a sixth-round draft pick in 2018, is establishing himself as a key player for the Toronto Blue Jays.

Moreover, his versatility on defense allows him to contribute at third base and both corner outfield positions.
For the Boston Red Sox, Brennan Bernardino is making notable strides after a less-than-ideal 2024. Previously an effective reliever, he has rebounded well this season, posting a 1.27 ERA and 3.34 FIP over 27 appearances, following a 4.06 ERA last year.
The Baltimore Orioles faced a challenging beginning to their season, yet Bryan Baker stood out as a positive aspect.
