SAN DIEGO -- Rockies catcher Jackson Williams, who made his Major League debut this season and appeared in seven games, underwent surgery on his right meniscus Wednesday, the club announced.

Williams, who suffered the injury in a Sept. 19 game against the D-backs, hit .214 (3-for-14) with one home run and three RBIs.

A supplemental first-round pick of the Giants (43rd overall) in 2007, Williams played in the Giants' system from 2007 to 13 before signing a Minor League deal with the Rockies this season. He played 72 games at Triple-A Colorado Springs and hit .256 with four home runs and 34 RBIs for the Sky Sox.
