ST. LOUIS — Pitcher Jaime Garcia has an impingement in his left shoulder and will rest for the next four weeks before being re-examined, St. Louis Cardinals General Manager John Mozeliak said Friday.

Garcia received a second opinion on his ailing shoulder Friday in California, where he was examined by Dr. Lewis Yocum.

"He reviewed the studies and also looked at (Garcia) himself," Mozeliak said of Yocum. "He basically is in agreement with what our medical staff sees.

"The recommendation right now would be to have him have four weeks of quiet time and therapy, then see where he's at after that."

Mozeliak said Garcia will receive a third opinion Monday from Dr. James Andrews in Birmingham, Ala.

Mozeliak also said there has been no discussion of surgery on Garcia's shoulder, which began bothering him after a two-inning start Tuesday in Houston.

Garcia, who is 3-4 with a 4.48 ERA in 11 games, had missed his previous start because of a sore elbow. Rest was prescribed, and Garcia missed his next turn.

An MRI on the elbow was clean, and the Cardinals were confident Garcia was OK to make his start Tuesday against the Astros.

But Houston ripped Garcia for six runs (earned) on five hits. After the game, Garcia acknowledged that something was wrong with the shoulder. The Cardinals' medical staff examined Garcia, who was placed on the disabled list with a strained shoulder Wednesday.

Joe Kelly will take Garcia's turn in the rotation Sunday against the Cleveland Indians, making his major-league debut.
