The Astros placed righthander Scott Feldman on the 15-day disabled list with a torn medial meniscus in his right knee Friday and called up hard-throwing righthander Michael Feliz from Class AA Corpus Christi.
Feliz, who made his Class AA debut Tuesday, will pitch out of the bullpen. Another move will be made to determine a starter for Monday. Lefthander Brett Oberholtzer, who is on a rehab assignment, appears like the top candidate to replace Feldman in the rotation.
Feldman is undergoing surgery on his knee in Houston. Feliz, who will celebrate his 22nd birthday early next month, is the second pitcher the Astros have called up before they threw a pitch at Class AAA.
