ST. LOUIS -- Pittsburgh Pirates catcher Ryan Doumit, who broke his left thumb on a passed ball, was put on the 15-day disabled list Wednesday.
Doumit is expected to miss at least four weeks. Surgery will not be necessary.
Doumit was hurt Tuesday night muffing a high strike in the first inning of the Pirates' 8-4 win in 10 innings over St. Louis. The switch-hitter is batting .350 with five homers and 15 RBIs.
The Pirates purchased the contract of 35-year-old catcher Raul Chavez from Triple-A Indianapolis. He was batting .306 in the minors with three home runs and 13 RBIs in 26 games.
