FORT MYERS, Fla. -- As part of the master plan to be conservative during the early weeks of Spring Training, Red Sox slugger David Ortiz isn't participating in team baserunning or conditioning drills yet. But he's doing his own agility work with the trainers and looks comfortable moving around.

"They are specific to his protocol," said manager John Farrell. "He feels not only that he's getting stronger, but with each passing day, there's less hesitancy to be a little bit more agile, a little bit more explosive. So I know that's a relative statement, but he's making good progress."

During batting practice, Ortiz certainly appeared comfortable, hitting bullets all over the field.

Middlebrooks showing no ill effects of broken wrist

FORT MYERS, Fla. -- The best way to gauge how well Will Middlebrooks has recovered from his right wrist fracture of last August is to listen to him take a round of batting practice.

"There's no limitations at all," said manager John Farrell. "When you see him take BP, the sound off his bat is different than most guys, even in this camp. He's fully healed from the fracture."

Middlebrooks doesn't even think about his wrist anymore. Instead, he's just focusing on getting ready for the season.

"It was a pretty simple rehab," Middlebrooks said. "I was in a cast for eight weeks and I got out and just did some strengthening things. It's not ligaments, it's not tendons, it was bone. So it was not really a whole lot of rehab. It was just kind of a waiting game, and I'm absolutely 100 percent right now. I feel normal now. I feel as it did before I got hit."

Buchholz advances to long toss

FORT MYERS, Fla. -- Red Sox right-hander Clay Buchholz has already advanced to long toss, three days after straining his right hamstring.

"Buchholz got out to 120 feet of long toss today," said manager John Farrell. "We've still got some functional running tests we've got to put him through before we turn him loose completely."

Lefty starter Felix Doubront, who was held back because of some mild shoulder weakness, will throw his first side session of camp on Wednesday. He's set to throw 135 feet during long toss.

Southpaw reliever Craig Breslow has also been on a conservative program. He threw 75 feet during his long toss on Friday.

"He's in the early phases of a throwing program," Farrell said. "As a reliever, he's got time on his side a little bit."
