BOSTON — With Shane Victorino back from the disabled list, Grady Sizemore's playing time has reduced.
He began this season as Boston's starting center fielder but now is platooning in left field with Jonny Gomes.
"The one thing he's been accustomed to when he's been healthy is been (being) an everyday player," Red Sox manager John Farrell said about Sizemore. "So the role he finds himself in here is a little bit different than he's been accustomed to.
"But he's an outstanding team player," Farrell added. "He understands Jonny Gomes is going to be in left field against left-handers. He stays prepared. His mindset is he comes to the ballpark knowing or thinking he's going to play every day. But I think nights like tonight go a long way in continuing to rebuild Grady."
Sizemore went 3 for 6 with two RBIs, including knocking in the game-winning run in walkoff fashion. The Red Sox won 4-3 over the Cincinnati Reds in 12 innings here at Fenway Park.
Sizemore singled home David Ortiz with no outs in the 12th after Ortiz and Mike Napoli singled to begin the inning.
It was Sizemore's fourth career walkoff hit but his first since Aug. 11, 2006. Of course, he didn't play the past two seasons because of injuries and hasn't had a fully healthy season since 2008 He has undergone seven surgeries since 2009.
"I think every first he goes through this year — first being since he was an everyday player — I've got to believe that he's feeling like the game's coming back to him in a way," Farrell said. "And he's doing some things he hasn't done for quite a while. To walkoff things off, I've got to believe tonight gives him even further feeling like he's contributing here rather than being someone coming back from an injury."
