FORT MYERS, Fla. -- Boston Red Sox manager John Farrell announced Friday morning that Grady Sizemore will be the team's Opening Day center fielder, a prospect that seemed almost unimaginable when camp opened six weeks ago.
But Sizemore, who has undergone seven surgeries since 2009 and had not played in a game at any level the last two seasons, has passed all physical tests this spring and showed few ill effects from his long layoff, batting .333 with a home run.
Rookie outfielder Jackie Bradley Jr. will open the season with Triple-A Pawtucket.
"To Grady's credit, he has answered the questions with his play, and he has responded physically," Farrell said.
Farrell shared his decision with the 31-year-old Sizemore, a three-time All-Star who signed a contract for a $750,000 base salary in late January, shortly before meeting with the media late Friday morning.
The manager said Sizemore took it in stride.
"He smiled," he said.
Sizemore, who was not scheduled to play Friday but said he will play in the team's exhibition finale Saturday, said he called his father, also named Grady, with the news.
"He took it in stride, like me," Sizemore said.
Sizemore was asked how this compared to making his first major league team as a 21-year-old in 2004.
"I'd say this was definitely a lot more satisfying," he said. "After going through what I've gone through, all the negative things that have happened, it's a long time since I've had positive news, a long time since I've been able to play, to feel this good in this setting, to look forward to coming to the ballpark not thinking, 'What's going to happen next? What's going to hurt today?' Everything's great."
Farrell said the plan is to continue with the same kind of progression that was prescribed for Sizemore this spring, where his playing time was gradually increased. Sizemore just played three games in a row, which is probably the same workload with which he'll begin the season, Farrell said.
"The durability with what we've been able to challenge him with, he's come out of it fine," Farrell said. "And even if he were to be asked to play today, he feels great to play a fourth consecutive day. However, we're not doing that based on the progression."
Sizemore said he wasn't even sure how much he would be able to run again in the wake of microfracture surgeries on both knees and a third knee procedure, as well as surgery on his back, elbow and two operations for sports hernias. He praised Dr. Dan Dyrek, the team's director of medical services, for laying out a comprehensive plan that has worked beyond Sizemore's fondest hopes.
"I think I'm getting there," Sizemore said when asked if he felt he could return to being the player he was before being injured. "I feel great now. I feel as good as I could have hoped coming in before camp, and I think there's still room for improvement.
"I'm not going to put high expectations on it. I'm going try keep improving on what I've done so far."
Farrell said the Red Sox don't believe that Sizemore has reached his ceiling.
