The St. Louis Cardinals activated catcher Yadier Molina from the 10-day injured list Tuesday.
Molina, 36, missed 11 games since being sidelined with a right thumb tendon strain on May 29.
The nine-time All-Star is batting .265 with four homers and 33 RBIs in 50 games.
To make room on the 25-man roster, the Cardinals optioned rookie backstop Andrew Knizner to Triple-A Memphis.
Knizner, 24, made his major league debut on June 2 and appeared in two games for St. Louis. He is 0-for-7 with one strikeout.
