PHILADELPHIA -- Red Sox right-hander Daisuke Matsuzaka received a cortisone shot in his right trap muscle on Sunday and will not pitch on Tuesday for Triple-A Pawtucket.

Tuesday would have been the last day that Matsuzaka, working back from Tommy John surgery, could have made a rehab start in the Minors. Pitchers are afforded 30 days of Minor League rehab time. But the shot, as a new development, should allow the Sox to reset that clock. Matsuzaka last pitched Thursday with Pawtucket, where he's given up nine runs in a combined 12 innings over his last two starts.

"Daisuke's not going to make his start on the 22nd," manager Bobby Valentine said. "He got another injection today in the right trap that's been nagging him for quite a while, and we got to make sure that's 100 percent before he's going out there again."

"He's going to, he'll be with us," Valentine said of the Minor League rehab clock, "and we'll monitor how that works in the next few days. You know, I just heard about it today. I talked with him {Saturday] about it, and he said he could maybe pitch through it and they examined him and didn't think it was wise."

A bothersome trapezius muscle, which affects the neck and shoulder, isn't in itself new for Matsuzaka. Valentine described the issue as chronic on Saturday, and had talked about it in early May as well.

Adrian, Papi both in lineup; Sweeney, Ross sit

PHILADELPHIA -- The way the Red Sox outfield's health situation has gone, the team is fortunate to have Adrian Gonzalez capable enough to play right field two consecutive days.

"I appreciate it a thousand percent," manager Bobby Valentine said. "And David [Ortiz] putting the glove on to go play first base, neither of them signed up for that, obviously. But they're willing to do whatever it takes and I appreciate it. I've said before, Adrian is, you know, always in the game, he's thinking of anything and everything that he can do and we can do to be as good as we can be, so his attitude is really appreciated."

Gonzalez started in right and Ortiz at first base again on Sunday, with Daniel Nava in left and Marlon Byrd in center. Ryan Sweeney was tested for a concussion after Saturday's 7-5 win over the Phillies, after he felt whiplash from a game-saving dive in right-center in the seventh inning.

"I'm doing all right," Sweeney said. "Yeah, I mean, did a concussion test and all that stuff, I don't know. I think it's OK. It's just my neck and stuff ... I was just out of it a little bit [Saturday] night. Yeah, I mean my neck's just a little sore today."

Asked if he would go the disabled list, Sweeney said "No, I'll be all right."

Valentine said he was being cautious with the concussion possibility. Needing some help in the meantime, the Sox optioned Mauro Gomez to Triple-A Pawtucket and recalled outfielder Che-Hsuan Lin, who was active for Sunday's game. Valentine didn't look at Gomez as a solid option in the outfield. Lin has hit .256 in 36 games with Pawtucket.

"I guess they have a test now that he says he couldn't pass before he dove for the ball," Valentine said of Sweeney. "But I guess they ask you to do things and recite the months of the year backwards. And that's a tough one. Things like that, and so he didn't do that well [Saturday] night, he said he felt much better today, his neck. He's in the training room with a kind of whiplash situation on his neck, which I don't think would prevent him from playing some."

The Red Sox did receive good news Sunday morning, with Cody Ross' left foot feeling much better after he fouled a ball off the foot Friday. He's not going to need a trip to the DL, Valentine said, and Ross said he could be ready for the Baltimore series that starts Monday. Pinch-hitting on Sunday might be too much to ask, though.

"I woke up this morning, I felt way better," Ross said. "I feel good ... Like 10 times better."

Down the pipe, Darnell McDonald (strained right oblique) and Jacoby Ellsbury (partially dislocated right shoulder) are both on the mend, with the former closer than the latter. McDonald indicated the injury had not fully disappeared yet, but said his rehab was going well and the trick was to get the inflammation down. He's taken anti-inflammatories.

"Darnell, talking to him [Saturday], he says he feels real good, he's initiating strength phase today," Valentine said. "And he's OK to perform light field work, including batting practice."

As for Ellsbury, Valentine said he's almost getting too strong, but has not started to swing and there's no timetable for a return. Ellsbury, like McDonald, is with the team in Philadelphia.

"I don't know if I can give you a timetable, he said he was feeling really good, he was doing a lot of weightlifting work and they thought he was even getting too strong," Valentine said of Ellsbury. "That he should take a little step back. He's progressing and started the strengthening phase of returning to play. He says his legs are really good, says he's not going to have to worry about getting them in shape, he's done everything possible to do the leg work and ab work and now it's just -- and his range of motion is good -- now it's strength which will lead to somewhere down the road, baseball activity."

Aviles makes it two leadoff homers in two days

PHILADELPHIA -- Before Saturday, Red Sox shortstop Mike Aviles had never led off a game with a home run. Now he's done it two straight days.

Aviles' eighth home run of the season and third in three days Sunday came off Phillies lefty Cliff Lee to left field in a 5-1 Sox win, the same part of Citizens Bank Park he took Joe Blanton out to Saturday during a 7-5 win.

Harry Hooper in 1913 is the only other Red Sox player to hit lead-off homers in back-to-back games.

"It was definitely fun, just going up there trying to set the tone, trying to get on base and fortunate to get a ball and run into a good part of the bat," said Aviles, who's 10-for-25 (.400) in his last six games, with four doubles, three home runs and six RBIs. "Pretty much, and get one up in the air."

"It's cool because I could say I got one," Aviles said after the first one on Saturday, "It definitely helps. I think it'll change the mood, definitely knowing that the first batter hits a homer and everybody else is, I guess can relax a little bit and get going ... It was cool."

Aviles is on a six-game hit streak and is hitting .275, up from the .254 his average dipped to following an 0-for-4 in a 6-1 win over Seattle on Monday.

"I think it goes in spurts," Aviles said. "I've been feeling good for the past week. It's just about having confidence in yourself and you know the way the spurts go."

Aviles has also played some of the best defense in the Majors at shortstop, according to the statistic Ultimate Zone Rating.

"It's kind of funny, everyone in Spring Training, that's the one thing they questioned about him," second baseman Dustin Pedroia said of Aviles' glove. "Everyone knows he can hit. But defensively, he's been unreal. All of his feeds are great, he's thinking the game out. We're always on the same page."

Manager Bobby Valentine, who's tried to dissuade the idea that a leadoff hitter has to do anything different, lauded Aviles Sunday.

"That's big, to do that two nights in a row here," Valentine said. "Relaxes the offense a little and let's the pitchers know that at least we have one when they go out there."

Swinging hot bat, Salty catches Beckett

PHILADELPHIA -- Catcher Jarrod Saltalamacchia got the start for the Red Sox on Sunday in a day game after a night game, and with a left-hander on the mound, for a straightforward reason: he's mashing.

"And Mike Aviles and Salty, it's the Mike and Salty show, huh?" manager Bobby Valentine said of his two hitters on a tear. "Back-to-back days. That's pretty good."

Two at-bats into Sunday's 5-1 win, Saltalamacchia hit a three-run homer to center, giving Boston a 5-0 lead against Cliff Lee and the Phillies through three innings. The rope cleared the seats and landed on the concourse for an estimated 466 feet -- farther than David Ortiz's shot to center Saturday in a 7-5 Sox win.

"I just made good contact with a 2-0 changeup," Saltalamacchia said. "I was able to put good wood on it. My only thought was man on third, need to get him in any way I can. It just worked in my favor."

Saltalamacchia normally hasn't started against lefties this season, but he's on a tear, with 11 knocks in 23 at-bats in his last six games, all of which included a hit. That's with four doubles and three home runs.

"Salty just feels really good," manager Bobby Valentine said before the game. "He and [Sunday starter Josh Beckett] had a good thing going last time, might as well ride that horse when he's feeling good."

Beckett had thrown primarily to Kelly Shoppach this season, but Beckett threw seven innings of shutout ball to Saltalamacchia one start before Sunday's. On Sunday, Beckett went 7 2/3 innings and let up just one run.

"He's doing a great job," Beckett said. "It's one of those deals where you're confident if you bounce a breaking ball that he's going to block it."

Saltalamacchia said before the last time he caught Beckett, on Tuesday, that he figured Valentine was going with a righty-lefty approach with he and Shoppach. That situation seems to have changed some.

"I don't know, this is just me: I think [Valentine is] starting to [have me] face righties, Shop faces lefties," Saltalamacchia said. "I think that's all it is."

Shoppach's health is fine, Valentine said.

Youkilis may rejoin Red Sox on Tuesday

PHILADELPHIA -- Red Sox third baseman Kevin Youkilis may rejoin the team Tuesday in Baltimore after playing with Triple-A Pawtucket on Monday.

"If he feels good after the game, I don't see any reason why not," manager Bobby Valentine said. "It's on him. He wants another couple at-bats, or if he needs anything."

Youkilis (lower back strain) did not play for the PawSox on Sunday and has had three rehab games with them. He's on the disabled list retroactive to April 29. Will Middlebrooks, the Red Sox's top prospect, has filled in for Youkilis admirably, hitting .275 with five home runs.

According to reports, Youkilis is drawing interest from other teams by trade.
