Kansas City Royals left-hander Tim Collins underwent season-ending Tommy John surgery.
Kansas City said Thursday the 25-year-old was operated on a day earlier by James Andrews.
Collins made his spring training debut against Texas on March 4 and left after two outs. An MRI revealed ligament damage.
He topped AL relievers with 93 strikeouts in 2012, but a left flexor strain last April put him on the disabled list for a month. He went 0-3 with a 3.86 ERA in 22 regular-season games and had a 3.18 ERA in four postseason games, including three World Series appearances.
With Collins out, Brian Flynn, Franklin Morales, and Brandon Finnegan are the leading lefthanded relief candidates.
New York Mets reliever Josh Edgin has a stretched left elbow ligament and tendinitis, and the team said he must decide between a conservative rehabilitation attempt or Tommy John surgery that would sideline him for about a year.
"A decision is expected in the next day or two," Mets general manager Sandy Alderson said. "It's not black or white. There's a certain amount of gray area here that requires some judgment on the physicians' part, as well as Josh deciding exactly how he wants to approach it."
The 28-year-old left-hander experienced elbow discomfort and gave up back-to-back RBI triples to lefthanded hitters in a 13-2 loss Monday to Miami.
Corey Kluber's big season hasn't been followed by a big contract. Not yet.
The AL Cy Young Award winner agreed to a one-year contract with the Cleveland Indians, who may still sign the steady righthander to a long-term deal.
Kluber gets paid at a salary of $601,000 while in the major leagues and $308,400 while in the minors, up from $514,000 and $277,300 last year. Kluber was the last Cleveland player on the 40-man roster to agree to terms.
Kluber vaulted from the middle of Cleveland's rotation to become the league's top pitcher last season, going 18-9 with a 2.44 ERA and 269 strikeouts.
CC Sabathia thinks he is ready for his first spring training start.
The New York Yankees lefthander threw 29 pitches broken down into two innings during his first simulated game of spring training. Sabathia is lined up to possibly pitch Tuesday.
The 34-year-old was hobbled by degenerative cartilage in his right knee that required surgery. He didn't pitch after May 10 last season.
"I'm not hurt. I feel good. That's the only way I'm judging myself right now," Sabathia said. "I'm encouraged."
The six-time all-star was 3-4 with a career-worst 5.28 ERA in eight starts last year.
Chris Capuano, the top candidate to be the Yankees' fifth starter, will likely be on the disabled list for the first month of the season after straining his right quadriceps while covering first base on a grounder Wednesday against Boston. He received a platelet-rich plasma injection for the injury.
