ST. LOUIS - Cardinals manager Tony La Russa was diagnosed with shingles and was having tests Tuesday at the Mayo Clinic, and it was uncertain when he would return to the team.
General manager John Mozeliak said he was waiting to talk with La Russa for an update. St. Louis started a series at Chicago on Tuesday night.
Bench coach Joe Pettini will run the Cardinals in place of La Russa, 66, who is in his 16th season as St. Louis manager.
La Russa's problem was initially identified in mid April as conjunctivitis, an inflammation commonly known as pink eye. But last week he called his illness a viral infection.
The entire right side of La Russa's face was swollen for a while, although La Russa continued to hit fungoes at practice until the last homestand.
