Hamstring tendinitis is the diagnosis.
"It's where the hamstring actually attaches a little below the knee, so I've got radiating pain when I sprint or do anything like that," said Drew. "It's a tendinitis kind of deal, but really irritated. I thought it would be something that would just kind of go away. I've never really felt anything like that. We've done some treatment, things like that, but I really kind of got to get it calmed down to not jeopardize injuring it real bad."
Drew, who has struggled mightily at the plate of late, does not think an MRI will be necessary.
"No, we know exactly what we're dealing with," said Drew. "It's nothing in the joint line or anything like that."
"Stimulation, massage, ice, heat it up, flush it out, things like that," said Drew. "Standard treatments."
There was good news on the injury front. Third baseman Mike Lowell was back in the lineup after getting plunked on the hand by a Chien-Ming Wang fastball on Friday night.
"Mikey Lowell is OK," said Red Sox manager Terry Francona. "That's why we got him out of there so he could probably play today and be OK. I think it worked."
Red-hot Pedroia bumped up: With Kevin Youkilis moving to the fifth spot in the order to replace Drew, rookie second baseman Dustin Pedroia batted second for the first time this season. Typically, Coco Crisp has been Boston's backup No. 2 hitter. But the way Pedroia is swinging the bat -- .486 over the last 11 games -- it was a no-brainer.
Pedroia's surge has been well-earned, according to his manager.
"I don't think you push a button. I think it's a process of a lot of hard work," said Francona. "When he was struggling, he didn't put his head down, he's got that fighter mentality. He goes to the cage every day. He had a lot of long sessions with [hitting coach Dave Magadan]. He got it in the cage, but he was having a hard time taking it to the field. Then it started translating into the game. You could see him getting more confident, which he should. [His] stride got a little less harsh."
Owning up to his thoughts: Red Sox principal owner John W. Henry let his feelings be known about the Scott Proctor fastball that sailed precariously close to the head of Youkilis.
"Proctor's intent was clear and disturbing," Henry wrote in an e-mail to The Boston Globe.
Henry witnessed the pitch from his front-row box seat right next to the Boston dugout.
"John owns the team, he's allowed to say anything he wants. I respect that," said Francona. "Being the manager, I just, we just want to go out and win today. It's dangerous and it's difficult to look into somebody else's intent or their thought process. That's just kind of how I feel. But John owns the team, he's allowed to look into my thought process or anyone he wants. That's part of it."
Ortiz due to power up: Sox slugger David Ortiz entered Saturday's game with no homers in 17 games and 60 at-bats, his longest drought since coming to Boston in 2003.
"Some of it is the way you get pitched, the way you feel physically," Francona said. "Before he sat those three days, I thought his swings were really good. I thought he just missed a couple. Now he comes back after sitting for three or four days and you can see he's using the whole field. He went out and hit extra, trying not to do more than you're ready to do and get yourself in a bind. I think this streak is a little bit artificial. He sat four days in between, his legs were bothering him. But he's using the whole field, he'll be fine."
On deck: Right-hander Josh Beckett will put his unbeaten streak to the test Sunday night when he faces Andy Pettitte in the finale of this three-game series. First pitch is slated for 8:05 p.m. ET.
