BOSTON -- Before Wednesday's game against the Rays, Red Sox players and coaches watched as Dustin Pedroia knelt on the grass by second base, taking grounders.

Pedroia, who broke his left foot Friday after fouling a ball off it, is trying to do anything to keep his arm in shape.

"I was out there for about five minutes. I am pretty bored. I really don't have a lot to do right now," said Pedroia, who is on crutches and is wearing a boot.

Even with Boston's second baseman expected to miss roughly six weeks, he is hoping to start walking on his foot in the next few weeks as he continues non-weight-bearing training.

Hearing about Pedroia's fielding drills before the game didn't surprise manager Terry Francona, who is trying to keep a close eye on the him.

"He's a maniac. He knows he can't put any weight on that foot and he knows he's going to slow himself down if he does," Francona said. "So, he'll abide by the rules, but he's gong to bend them as much as he can."

While the injury will keep him out awhile, Pedroia has a clear objective in sight.

"I have been doing my treatment all the time," he said. "Hopefully it doesn't take six weeks and I am back earlier than that. It is my goal.

"Hopefully I heal fast and it won't be that long, I will be all right. If we keep winning, I will be fine. If we start losing, I might panic and start walking, but I will be all right."

Patterson makes Red Sox debut

BOSTON -- Ready to give left fielder Daniel Nava a day off, Red Sox manager Terry Francona penciled in recently acquired utility player Eric Patterson for Wednesday's game against the Rays.

"Nava's been playing a lot. I just thought it would be really good for him to get a day off, and again, I just wanted Patterson to play," said Francona.

The utility man was acquired from the A's on Saturday in exchange for pitcher Fabian Williamson.

This season, Patterson has played 25 games in left field, seven in center field and five at second base.

"The idea is he gives us some flexibility, we can move guys all around, and he can run," Francona said. "So, even on the days when he doesn't play, we can certainly do some things off the bench."

This season, Patterson has been successful in all six of his stolen-base attempts. He understands how much his speed on the basepaths will determine his playing time and role with Boston.

"I get that speed is part of my game, and [I'll] look for situations where I can get in there and take advantage of that," Patterson said. "It has always been a big part of my game."

In 45 games with the A's in 2010, Patterson batted .204 with four home runs, nine RBIs and 13 runs scored.

Francona happy Doc's staying

BOSTON -- As news spread throughout Boston that Celtics head coach Doc Rivers would return for another season, one person became particularly excited at the development: Terry Francona.

The Red Sox manager, who is a close friend of Rivers, said he learned of the development early Wednesday afternoon.

"From a personal standpoint, I'm thrilled. I hope he is, too," Francona said. "It sounds like there was a lot of thinking involved."

Francona also joked that with the news, he will renew his 2010-11 season tickets as soon as possible.

"From personal experience after a season like that, I think you're probably exhausted," Francona said. "I hope he's really happy with his decision. I would imagine he is, or he wouldn't have come back."

Worth noting

Red Sox right fielder J.D. Drew was a late scratch Wednesday with a stiff neck, and was replaced in right field by Darnell McDonald.
