Hard-luck outfielder Grady Sizemore on Thursday underwent his sixth surgical procedure in four years, this time on his lower back.
The Cleveland Indians said Sizemore's recovery will take two to three months.
Sizemore, 29, tweaked his back last month while fielding ground balls.
Once considered a rising star with the Indians, Sizemore also has had surgery on both knees, two operations for sports hernias, and a procedure on his left elbow -- all since 2008.
LACKEY FINALLY PAIN-FREE
After struggling with pain for two seasons, Boston Red Sox right-hander John Lackey is prepared to sit out 2012 as he recovers from Tommy John surgery.
"At least when this is over I'm looking forward to pitching healthy again," the 33-year-old right-hander told the Boston Globe. "For sure I'm going to miss competing and being out there, but this had to be done.
"Dr. (Thomas) Gill told me I had one of the biggest bone spurs he'd ever seen and of course the damage that led to the Tommy John surgery."
Lackey, who was 12-12 with a 6.41 earned-run average in 2011, slowly is rehabbing by throwing at a 45-foot distance every other day.
NAPOLI SEEKS FREEDOM
Catcher Mike Napoli, 30, will test free agency after the season after failing to get a muli-year contract done with the Texas Rangers during the winter.
Napoli, who settled instead for a one-year, $9.4-million deal with Texas, said talks for a long-term deal have been "squashed."
"I'd love to be here, but I'll test the market," Napoli told the Fort Worth Star-Telegram.
Napoli hit .320 in 2011 with 30 home runs and 75 RBI.
TIME'S UP FOR VARITEK
Jason Varitek battled his emotions Thursday as he announced his retirement from the Boston Red Sox.
"After months of deliberating what to do, I decided that it's best to me and my family to retire a Red Sox," said Varitek, who had to pause several times during his speech. "This has probably been the most difficult decision of my career."
The 39-year-old spent 15 years as a catcher with the Red Sox -- the last seven as team captain -- and was a three-time all-star.
