Miami Marlins seek bullpen upgrades as Sandy Alcántara leads postseason push

At the All‑Star break the Miami Marlins held a 52‑45 record, securing the National League wild‑card spot and facing a tight race with teams such as the San Luis, Pirates, Arizona and San Diego. The club is counting on Dominican right‑hander Sandy Alcántara, who posted a 3.99 ERA, a 10‑5 record, a 1.22 WHIP and an average fastball speed of 97.4 mph. In his most recent start before the break he delivered seven solid innings against the Guardians, allowing three runs while striking out eight.

Front office analysts say the Marlins must improve the back end of their bullpen before the trade deadline. Media reports highlight two potential left‑handed options: Boston Red Sox closer Aroldis Chapman, 38, who once threw a 105.8 mph pitch, and Houston Astros reliever Josh Hader. Adding a high‑quality lefty could help Miami maintain its playoff drive.
