Cardinals' McClellan (shoulder) out for season

Cardinals' right-handed pitcher Kyle McClellan will miss the rest of the season after undergoing shoulder surgery Tuesday.

McClellan, on the disabled list since May with a right elbow strain, required surgery after he tore the labrum in his right shoulder during a throwing session.

A starter to begin the 2011 season, McClellan appeared in 43 games, including 26 out of the bullpen last season.

He was 0-1 with a 5.30 ERA in 16 relief appearances in 2012.
