NEW YORK -- The Boston Red Sox have put star second baseman Dustin Pedroia back on the 10-day disabled list for the third time this season because of knee trouble.
The AL East leaders made the move before playing at Yankee Stadium on Saturday. The move was retroactive to Thursday, and left-hander Robby Scott was recalled from Triple-A Pawtucket.
Pedroia is out with inflammation. He has been hobbled by knee problems since being injured in a late slide by Manny Machado in Baltimore on April 21.
The 33-year-old Pedroia leads the team with a .303 batting average and a .378 on-base percentage. He has six home runs and 54 RBIs.
Pedroia tops major league second basemen with a .997 fielding percentage, making only one error this year. That miscue ended his Red Sox-record of 114 straight games without an error by a second baseman.
Pedroia was 0 for 4 as a designated hitter Wednesday at Tampa Bay in his first game since July 28. He also was on the DL from May 30 to June 9.
Scott was 1-1 with a 3.38 ERA in 41 games for Boston this year (see full story).

Yankees: RHP Tanaka placed on DL with shoulder inflammation
NEW YORK -- The New York Yankees have put right-hander Masahiro Tanaka on the 10-day disabled list because of shoulder inflammation.
The Yankees made the move Saturday before hosting the AL East-leading Boston Red Sox. Righty Giovanny Gallegos was recalled from Triple-A Scranton/Wilkes-Barre.
Tanaka issued a career-high five walks in four-plus innings at Toronto on Wednesday. After the game, Tanaka told the team he was ailing.
"We decided he needs a break," manager Joe Girardi said.
Girardi said there is nothing structurally wrong with Tanaka. Rather, he'll rest and strengthen his shoulder, and is expected back soon.
The former Japanese ace is 8-10 with a 4.92 ERA in 23 starts during an up-and-down season. He was scheduled to start Monday night when the New York Mets play at Yankee Stadium.
Girardi said Bryan Mitchell and Luis Cessa are candidates to pitch in Tanaka's place (see full story).
Yankees: LHP Montgomery OK after hit in head at batting practice
NEW YORK -- Yankees pitcher Jordan Montgomery is in uniform after being hit in the head by a flyball while signing autographs as the Boston Red Sox took batting practice.
The accident happened Saturday while the AL East-leading Red Sox warmed up at Yankee Stadium.
The Yankees said the 6-foot-6 rookie was examined by the team's medical staff. The club said Montgomery was expected to make his start Sunday night against Boston ace Chris Sale.
Montgomery was in foul territory far down the right field line and behind a protective screen when the ball flew over and struck him. He got help leaving the field. It was not known which Red Sox player hit the ball.
Montgomery is 7-6 with a 4.05 ERA in 21 starts for New York since making his major league debut this season.
The lefty recently lost his rotation spot and was sent to the minors when the Yankees traded for starters Sonny Gray and Jaime Garcia. He was recalled from Triple-A when CC Sabathia was put on the disabled list Friday.
