BOSTON — Boston Red Sox shortstop Jed Lowrie had surgery on his left wrist Tuesday and should be ready to swing a bat in six weeks.

Lowrie, who had cartilage repaired during the surgery in Arizona, played with the injured wrist last season. He tried to rehabilitate it during the offseason but went on the disabled list on April 13 after going 1-for-18 in five games.

"Everything that was done today puts him on track to start swinging the bat in six weeks, which is what the hope was when this came up," Boston manager Terry Francona said.

Nick Green, signed as a minor league free agent in January, was batting .240 in eight games as Lowrie's replacement. Shortstop Julio Lugo, recovering from right knee surgery, planned to begin a rehabilitation stint Tuesday at Triple-A Pawtucket but the game was rained out.

The Red Sox placed outfielder Rocco Baldelli on the 15-day disabled list after he strained his left hamstring Monday in a win over the Baltimore Orioles and recalled Jeff Bailey from Triple-A Pawtucket.

Baldelli is batting .231 in 13 at bats. Bailey was hitting .255 with four homers in 47 at-bats at Pawtucket.
