As the 2025 fantasy baseball season kicks into gear, several underperforming players are on the hot seat, with many still being highly rostered despite their lackluster starts. Mark Vientos of the New York Mets, with a dismal .119 batting average, is struggling to find his rhythm, and his OPS of .412 raises concerns about his ability to maintain a spot on fantasy rosters. Similarly, Spencer Steer from the Cincinnati Reds has seen his performance drop sharply, leading to a demotion in the batting order after starting with high expectations.

Yandy Diaz of the Tampa Bay Rays also faces scrutiny as his batting average plummets to .143, leaving fantasy managers questioning his viability. Meanwhile, Bailey Ober's inconsistent pitching for the Minnesota Twins has many debating whether he should remain in their lineups, especially following a rough start in his season debut. Ronel Blanco of the Houston Astros, who showed promise last year, is struggling to recreate his success and has a concerning ERA of 9.45. As Week 3 approaches, the need to reassess these players is crucial for fantasy success.
