The St. Louis Cardinals have made a change to their bullpen, optioning second-year reliever Andre Pallante to the minors and calling up left-hander JoJo Romero.
Pallante has struggled in his eight appearances, allowing seven earned runs. The demotion comes after Pallante allowed a walk and home run on Monday.
Romero has appeared in five games for Memphis this season, pitching to a 1.59 ERA while striking out 11 batters. Last season Romero appeared in 15 games for the Cardinals after being acquired in a trade with the Phillies.
