The Red Sox said in an e-mailed statement that the surgery is scheduled for tomorrow. The team did not say when Bailey, a right-hander, is expected to return.
Bailey, 27, a two-time All-Star, had 75 saves in his three seasons with Oakland. Bailey converted 24 of his 26 save opportunities in 2011, a 92.3 percent success rate that was second highest in the American League.
