ST. LOUIS — The St. Louis Cardinals placed catcher Yadier Molina on the injured list with a strained right thumb and activated infielder Matt Carpenter as part of a series of roster moves Thursday.
Molina's move to the IL was retroactive to Monday. The nine-time All-Star, who missed 12 games in May and June with a similar injury, pinch hit on Saturday but hasn't started a game since June 3.
However, it could be August when Molina returns from the torn tendon that has troubled him and not recovered as hoped.
"I don't want to put a timetable on it," Cardinals manager Mike Shildt said. "But you're looking at beyond the 10 days. You're probably looking within a three-week range."
Carpenter has been sidelined since June 29 with a lower back strain.
Also, the Cardinals purchased the contract of left-handed reliever Chasen Shreve from Memphis.
Shreve, acquired with right-hander Giovanny Gallegos from the New York Yankees last year for first baseman Luke Voit, had been outrighted to Memphis.
Shreve takes the place of reliever Jordan Hicks (elbow surgery), who was moved to the 60-day IL from the 10-day IL.
Additionally, catcher Andrew Knizner was recalled and first baseman Rangel Ravelo optioned there.
Shreve appeared in 20 games for the Cardinals last season and is 2-1 with a 3.80 ERA in 37 games for Memphis this season. Kinzer made his big league debut June 2, going 0 for 7 for St. Louis.
