SAN DIEGO — Injured St. Louis Cardinals pitcher Jaime Garcia will undergo surgery on his troublesome left shoulder Friday.
The operation will be performed by Cardinals team physician Dr. George Paletta. Garcia was examined Wednesday in Pensacola, Fla., by orthopedic surgeon Dr. James Andrews, who diagnosed a torn labrum. Garcia was placed on the disabled list Sunday.
The surgery will sideline Garcia, 26, for the remainder of the season and possibly part of next season.
Garcia said Saturday that he began experiencing discomfort in the shoulder three starts ago, explaining that the pain was worse than last year when he was out of action with the same issue.
Garcia is 5-2 with a 3.58 ERA in nine starts this season. He has been replaced in the rotation, for the time being, by rookie left-hander Tyler Lyons, who made his big-league debut Wednesday in San Diego.
The Cardinals purchased Lyons' contract Wednesday from Class AAA Memphis and placed right-handed reliever Fernando Salas on the 15-day disabled list, retroactive to Tuesday, because of right shoulder inflammation.
Lyons, 25, started for St. Louis on Tuesday at San Diego. Lyons was drafted by the Cardinals in the ninth round of the 2010 draft out of Oklahoma State.
The native of Lubbock, Texas, was 2-1 with a 4.47 ERA in eight starts for Memphis this season. He threw a no-hitter for high-Class A Palm Beach in 2011 in his seventh career professional start.
Lyons will wear uniform No. 70. He becomes the fourth Cardinals pitcher to make his big-league debut this season, joining Seth Maness, Carlos Martinez and John Gast.
Lyons and Gast become the first pair of rookie Cardinals left-handers to start games in the same season since 1980 when John Martin and Al Olmsted both did so.
The Cardinals have 10 six rookies on their staff, more than any other major-league team.
Salas, 27, was 0-2 with a 3.86 ERA in 15 games. He worked one-third of an inning Monday in the opening game of the San Diego series, lost by the Cardinals 4-2. St. Louis won 10-2 on Tuesday.
