NEW YORK -- The Red Sox announced that after being examined by team medical director Dr. Thomas Gill, Dustin Pedroia has been diagnosed with having a bone bruise on his right knee cap. The second baseman will rejoin the team in Toronto Friday.

The Red Sox will start Marco Scutaro at second base and bat him second in the final game of their three-game series with the Yankees on Thursday in New York. Scutaro is in the lineup in place of Dustin Pedroia who returned to Boston to have his knee examined.

The Sox took the first two games of the series and have Josh Beckett on the mound for the finale against Yankee lefty C.C. Sabathia. Here is the rest of the Sox lineup:

Former Red Sox prospect Anthony Rizzo will be added to the roster of the Padres on Thursday and is expected to make his major league debut against the Nationals.

The 21-year-old Rizzo -- acquired by the Padres in the Adrian Gonzalez trade -- was batting .365 with 16 home runs and 63 RBIs for Triple-A Tucson, and his 1.159 OPS led all Pacific Coast League players. 

NEW YORK -- Dustin Pedroia will return to Boston Thursday to have his right knee examined. The ailment has been bothering him since landing on the knee during the Red Sox' game against the Orioles May 16.

The examination will be held at Massachusetts General Hospital and is viewed as precautionary, with the team wanting to ensure that the injury won't get any worse by continuing to play. While it is the same knee Pedroia experienced structural issues with during the 2010 season, the current injury is not related to last season's ailment. 

NEW YORK -- The Red Sox claimed sole possession of first place in the American League East thanks to a 11-6 win over the Yankees on Wednesday night at Yankee Stadium. The Sox jumped out to a 7-1 lead after four innings and never looked back.

The Sox put on an offensive show against Yankees starter A.J. Burnett and relievers Boone Logan and Lance Pendleton, managing 11 hits, including home runs by David Ortiz, Carl Crawford and J.D. Drew. Jacoby Ellsbury continued his hot hitting, coming away with three hits, while Marco Scutaro and Crawford each claimed a pair.

NEW YORK -- Red Sox reliever Rich Hill will undergo Tommy John surgery to repair a torn ligament in his left armThursday in Pensacola, Fla., with Dr. James Andrews performing the procedure. Starter Daisuke Matsuzaka will also have Tommy John surgery, with his operation scheduled to be performed by Dr. Lewis Yocum Friday.

Hill appeared in nine games for the Sox in 2011, allowing no runs and just three hits while striking out 12 and walking three in eight innings. The lefty hadn't allowed a run in 15 games with the Red Sox since joining the team in '10.

NEW YORK -- The Red Sox have placed reliever Bobby Jenks on the DL with a back injury and have recalled catcher Luis Exposito from Triple-A Pawtucket.

"It's [back injury] just from pitching," said Jenks, who left the Tuesday's game after throwing just four pitches in the seventh inning and had an MRI Wednesday. "It's literally a muscle that's about this big, and I tore it a bunch of years ago. It's one of those things that just comes and goes every now and then. It's on my left side, right behind my left [scapula]."

NEW YORK -- The Red Sox look to continue their 2011 domination of the Yankees on Wednesday night at Yankee Stadium. The Sox (34-26) beat the Yankees (33-25) by a final of 6-4 on Tuesday, the sixth win in seven games vs. New York this season.

Tim Wakefield (2-1, 4.40) will get the start for the Sox. Wakefield has a record of 11-17 with an ERA of 4.90 in 56 career appearances against the Yankees. A.J. Burnett (6-3, 3.86) will start for the Yankees.

Lineup:

Ellsbury, CF

Pedroia, 2B

Red Sox manager Terry Francona joined The Big Show for his weekly chat and touched on a number of subjects including the health of Clay Buchholz and Bobby Jenks, how Jonathan Papelbon's impending suspension affects the team, as well as the impact of David Ortiz's bat flip after he hit a home run in the Sox' 6-3 win over the Yankees on Tuesday, which drew the ire of Yankee manager Joe Girardi.

Peter Gammons made his weekly appearance on the Mut & Merloni show Wednesday to talk about the Red Sox, who started a three-game series in New York with a 6-4 victory over the Yankees Tuesday night.
