ATLANTA -- Braves left-hander Jonny Venters will be shut down for a month after receiving a platelet-rich plasma injection in his sprained pitching elbow.
The team announced Tuesday that Venters was examined by Dr. James Andrews, who performed ligament-replacement surgery on Venters' elbow in 2005. The pitcher felt tightness in his elbow during his last spring training game and was placed on the 15-day disabled list on Sunday.
The Braves say Venters will be shut down for four weeks, then begin a throwing program.
Santana undergoes surgery
NEW YORK -- New York Mets pitcher Johan Santana has had shoulder surgery for the second time in 31 months.
The Mets said the 34-year-old left-hander was operated on Tuesday at the Hospital for Special Surgery. Mets medical director David Altchek repaired a tear in the capsule in the front of his left shoulder. The team said the two-time Cy Young Award winner will be hospitalized overnight.
Santana is likely to miss the entire season for the second time in three years. He had surgery on Sept. 14, 2010, to repair tears in the front and bottom of the shoulder's anterior capsule and did not make it back to the major leagues until last April 5.
New York still owes Santana $31 million from his $137.5 million, six-year contract. General manager Sandy Alderson said the remainder of the contract is not covered by insurance.
Marcum suffers setback
NEW YORK -- Shaun Marcum was unable to pitch a simulated game for the New York Mets because of pain in his neck and will not be able to come off the disabled list to start Sunday against the Miami Marlins.
Marcum had been set to throw Tuesday at the team's spring training complex in Port St. Lucie, Fla.
Marcum signed with the Mets during the offseason. He received a cortisone injection in his right shoulder for an impingement last month, then felt neck discomfort during a bullpen session on March 25. He did not pitch in any spring training games after March 16.
Aaron Laffey and Collin McHugh appear to be the most likely candidates to replace Marcum. Already missing injured ace Johan Santana, New York has a rotation that includes Jonathon Niese, Matt Harvey, Dillon Gee and Jeremy Hefner.
