HOUSTON (AP) - Houston All-Star catcher Jason Castro has been placed on the 15-day disabled list with discomfort in his right knee, ending his season.
Castro had a cyst in his right knee drained on Sept. 3 and appeared in two games at designated hitter since then, but has not played defense.
The Astros hoped that he would respond to treatment and be able to return this season, but decided Tuesday that it would be better to shut him down.
The 26-year-old Castro set career highs in games played (120), batting average (.276), home runs (18) and RBIs (56).
Castro was selected the American League player of the week twice this season.
