JoJo Romero took over the role of closer for the St. Louis Cardinals following the trade deadline of Jul. 31, 2025, 6 p.m ET. Before July, Romero had zero blown leads and was one of the Cardinals' best relievers with an ERA of 2.12 before August.
The southpaw Romero has pitched 51 games, the most of any Cardinal pitcher, and ahead of his save on Aug. 10 against the Cubs, Romero had allowed just one earned run. Things have not gone as well for Romero as of late, but he's still be one of the most valuable relievers in all of baseball on the year.
