Andrew Painter of the Philadelphia Phillies, Robert Hassell III from the Washington Nationals, and Spencer Jones of the New York Yankees are highlighted as top fantasy baseball prospects worth stashing. Painter, a promising right-handed pitcher, has rebounded from a rough start in Triple-A, showing strong potential with a recent 2.51 ERA over his last three outings. Hassell, an outfielder, has demonstrated significant production in the minors following a brief MLB stint, posting an impressive .455/.556/.955 line after returning. Meanwhile, Jones has shown power and speed, hitting .403 in his last 16 games with 8 home runs, though concerns about his high strikeout rate remain. These players could provide valuable contributions during the second half of the season, making them essential targets for fantasy managers.

Week 14 brings exciting prospects to watch as fantasy baseball managers look to bolster their rosters. Moises Ballesteros, the Chicago Cubs' No. 4 prospect, is making a case for a call-up. Despite a rocky MLB debut, he has excelled in Triple-A with a .310 batting average, showcasing his ability to draw walks and limit strikeouts. The Cubs may need his offensive spark, especially with injuries affecting their depth at catcher.

Another name to consider is Robert Hassell III of the Washington Nationals. While his initial stint in the majors was less than stellar, he has rebounded impressively in Triple-A, hitting .455 over his last five games. The Nationals' outfield situation opens a potential pathway for his return, particularly if he continues this hot streak.

Lastly, Hunter Barco, a left-handed pitcher for the Pittsburgh Pirates, is garnering attention after a strong showing at Double-A. Though he has faced challenges in Triple-A, his recent performance suggests he may soon find his way into the Pirates' rotation, making him a player to monitor closely for potential late-season contributions in fantasy leagues.

As the 2025 MLB season approaches its midpoint, fantasy managers are buzzing about the latest crop of prospects making their major league debuts. With injuries and performance struggles afflicting many teams, organizations are turning to their minor league systems for fresh talent to bolster their rosters.

Jac Caglianone, first baseman for the Kansas City Royals, is making headlines after a dominant minor league campaign, hitting .322 with 15 homers. He’s expected to get significant playing time as a right fielder. Cole Young, now with the Seattle Mariners, is also a name to watch after a solid stint in Triple-A, offering potential at second base. Meanwhile, the Boston Red Sox have called up Marcelo Mayer, whose impressive minor league stats suggest significant upside despite a slow start at the big league level.

Marcelo Mayer, the Boston Red Sox's highly touted prospect, has made his MLB debut, showcasing promising talent in his first few games. The 22-year-old, ranked No. 8 on MLB's top prospects list, demonstrated his capability with notable hits and an impressive OPS. However, his groundball tendencies and struggles with non-fastball pitches may challenge his consistency against major league pitchers.

Denzel Clarke debuted with the Oakland Athletics but faced early struggles, managing only one hit in 19 at-bats. Known for his size and speed, Clarke's high strikeout rate poses concerns, highlighting the need for adjustment at the major league level. Meanwhile, Robert Hassell III of the Washington Nationals has shown flashes of potential since his promotion, including a three-hit game and his first home run. With a solid batting average in Triple-A prior to his call-up, he could be a key player as the Nationals rebuild post-Juan Soto trade.

Robert Hassell III of the Washington Nationals emerges as a key fantasy baseball pickup for Week 9 of 2025. Promoted recently, he's currently ranked as the No. 11 prospect in the Nationals' system. In his brief stint at Triple-A, he showcased impressive stats with a .288 batting average and nine stolen bases. Though he had a rocky start in the majors with a hitless streak, his initial debut was promising with a 2-for-5 performance including a stolen base. With injuries affecting teammates Jacob Young and Dylan Crews, Hassell is expected to secure a regular starting role.
