The 2025 fantasy baseball season has seen several closers falter, including Ryan Helsley of the St. Louis Cardinals, who has recently struggled with blown saves, and Raisel Iglesias of the Atlanta Braves, who lost his closer role after poor performances. Amidst this uncertainty, the top-performing closers include Josh Hader from the Houston Astros, who leads the league with 17 saves and boasts an impressive strikeout rate. Other notable names are Andres Munoz of the Seattle Mariners and Robert Suarez from the San Diego Padres, both of whom are expected to maintain strong performances for the remainder of the season.

This analysis also looks forward to predicting the top 10 closers by October. The expectation is that the likes of Hader and Munoz will remain at the forefront. New faces preparing to emerge in the closing ranks include Mason Miller and Luke Weaver, with Miller showing significant promise as a newcomer. With the trade deadline approaching, it will be interesting to see how trades impact closer dynamics in the league.
