As the 2025 fantasy baseball season progresses into Week 4, the early struggles of several starting pitchers raise concerns for fantasy managers. Holding onto underperforming pitchers can seriously impact a team's ERA and WHIP, making timely roster decisions crucial. Here’s a look at five pitchers currently on the hot seat, including Jose Berrios, Jeffrey Springs, Justin Verlander, Jordan Hicks, and Reese Olson, each facing critical junctures in their seasons.

Jose Berrios has had a shaky start this season with a 5.16 ERA and a 1.46 WHIP, suggesting it might be time to cut him loose unless he shows improvement against favorable matchups. Jeffrey Springs, now with the Athletics, is also under scrutiny, especially in a hitter-friendly environment. Despite a promising previous season, his transition has been rocky, and he should be used selectively based on matchups. Justin Verlander, though struggling, possesses a favorable SIERA and could be worth holding for potential quality starts, especially at home. Meanwhile, Jordan Hicks faces competition for his spot and must perform well in upcoming games to secure his place on rosters. Lastly, Reese Olson's slow start poses a dilemma, and his performance against weak opponents could determine his fate in fantasy lineups.
