As fantasy managers approach Week 15 of the 2025 MLB season, some players' performances are raising eyebrows and leading to tough decisions. Catcher Austin Wells of the New York Yankees is a candidate for dropping due to his low .215 batting average, hampered by a circulatory issue in his hand. Despite decent counting stats, his poor average makes him a risky hold in shallower leagues. Similarly, Taj Bradley of the Tampa Bay Rays is struggling with a 4.79 ERA and has seen a drop in strikeouts, making him less trustworthy.

Meanwhile, Tommy Edman of the Los Angeles Dodgers is worth holding onto despite an ankle injury, as his underlying stats suggest he could bounce back. Chris Bassitt of the Toronto Blue Jays has been inconsistent but still provides fantasy value due to his durability and strikeout potential. Paul Goldschmidt is on the hot seat, as his recent performance has dipped despite a strong start. Zac Gallen and Tyler Soderstrom also appear on the radar for roster adjustments, with Gallen's delayed potential and Soderstrom's cooling off notable.

In Week 15 of the 2025 MLB season, fantasy baseball enthusiasts have several exciting prospects to consider stashing. Carson Williams, a shortstop for the Tampa Bay Rays, is showing signs of significant improvement, boasting a .326 average with five home runs in his last 12 games. With the Rays in playoff contention and their shortstop situation uncertain, he could make his MLB debut soon if his power surge continues.

Jonathon Long, a versatile first baseman-third baseman for the Chicago Cubs, has also impressed at Triple-A Iowa, posting a .317 average with 13 home runs this season. However, his path to the MLB is complicated by the Cubs' crowded roster, indicating that he may only serve in a reserve role initially. Lastly, Cam Schlittler, a right-handed pitcher for the New York Yankees, has been on a roll with a stellar ERA at Triple-A and is now set to be promoted, making him a valuable addition to fantasy rosters.

Joe Boyle, after a rocky start with the Athletics last season, has shown significant improvement since being traded to the Tampa Bay Rays. The right-hander has been dominating in Triple-A, posting an impressive 1.85 ERA with a 96:31 strikeout-to-walk ratio over 73 innings. His recent outings have highlighted his potential, making him a relevant name in the fantasy baseball scene as the Rays push for a Wild Card spot.

Despite his performance, Boyle currently lacks a clear path to the major league rotation due to Taj Bradley holding the fifth spot. However, should an injury occur, Boyle is likely to be a top candidate for a call-up, making him an essential stash for fantasy managers looking to capitalize on his upward trajectory.

The Tampa Bay Rays are facing a significant challenge as their bullpen has faltered in crucial moments, resulting in back-to-back losses against the Minnesota Twins. After a disappointing blown save on Friday, the Rays’ relievers allowed a 5-1 lead to slip away in Saturday's game, leading to their fourth consecutive defeat. Manager Kevin Cash expressed concern but emphasized confidence in the bullpen, noting that recent struggles are part of the game. With a tough road schedule and the All-Star break approaching, the timing of these losses raises questions about potential trade moves before the deadline. The pressure mounts as the bullpen, once praised, must regain its form to support a struggling offense.

Dynasty fantasy baseball is dynamic, with new stars challenging for dominance at their positions each season. This year, several young talents are making a significant impact, notably Cal Raleigh of the Seattle Mariners, who has set a record for catchers with 35 home runs, dwarfing the competition. Raleigh's all-around performance, with a wRC+ of 184, positions him as the top catcher in dynasty leagues.

Meanwhile, Nick Kurtz has emerged as a strong contender at first base, showcasing his power with 13 homers in just 200 at-bats. Despite an initial slow start, Kurtz's stats reflect a promising future, potentially overtaking older stars like Vladimir Guerrero Jr. Junior Caminero has also made waves, establishing himself among the elite third basemen with 21 home runs this season. Lastly, James Wood of the Washington Nationals is proving to be a formidable outfield prospect, hitting 23 home runs and stealing 12 bases, solidifying his status in dynasty leagues.
