SAN DIEGO (AP) St. Louis rookie shortstop Aledmys Diaz will replace his teammate, infielder Matt Carpenter, on the National League roster for next week's All-Star game.
The American League also made a change, with Cleveland right-hander Corey Kluber stepping in for Toronto pitcher Marco Estrada, who has been placed on the 15-day disabled list.
The replacements were announced Thursday by NL manager Terry Collins of the New York Mets and AL manager Ned Yost of the Kansas City Royals.
