The Cardinals announced on Tuesday that the club activated 3B/SS Jhonny Peralta and activated 1B/OF Brandon Moss from the 15-day disabled list. The club also added recently acquired reliever Zach Duke to the 25-man roster.
In order to create roster space, the Cardinals placed shortstop Aledmys Diaz on the 15-day disabled list and optioned pitcher Dean Kiekhefer and outfielder Randal Grichuk to Triple-A Memphis.
Losing Diaz is a pretty big deal for the Cardinals. He suffered a hairline fracture in his right thumb when he was hit by an Andrew Cashner pitch on Sunday. Diaz is in the running for the NL Rookie of the Year Award, batting .312/.376/.518 with 14 home runs, 57 RBI, and 64 runs scored in 401 plate appearances.
Peralta, who had been playing third base due to Diaz’s breakout season, will return to shortstop. He had been on the disabled list with renewed soreness in his surgically repaired thumb. In 120 PA this season, the veteran has a meager .221/.258/.416 triple-slash line with five home runs and 13 RBI.
Moss had been on the disabled list since July 5 with a sprained left ankle. He went 0-for-8 in three rehab games. He’ll try to improve on his .256/.344/.566 triple-slash line with 17 homers and 40 RBI in 250 PA.
The Cardinals acquired Duke ahead of Monday’s trade deadline, sending outfield prospect Charlie Tilson to the White Sox.
