BOSTON – A week ago, the Red Sox arrived home from a disappointing 3-7 road trip, looking up at the first-place Rays – owners’ of baseball’s best record at 55-32 – with the Sox five games back, seven games back in the loss column.What a difference a week makes. Since then, Tampa Bay has lost seven consecutive games while the Sox reclaimed sole possession of first place in the American League East with yesterday’s 2-1 win over the Orioles at Fenway Park in front of 37,344.Although not dominant, Daisuke Matsuzaka improved to 10-1, the first Sox pitcher to reach double-digit wins, with a 2.65 ERA, throwing 115 pitches (68 for strikes) in six scoreless innings. He gave up four hits and five walks, hit a batter, and struck out seven.”The good news is he gets out of it,” Sox manager Terry Francona said. “There’s some frustration at times, which I think he probably has, too, because his stuff is so good and he has the ability to get outs. When he locates, he’s as good as there is. He created some jams for himself – got a walk, hit batsman, walk. But, fortunately, they didn’t string together a couple of hits.””First, I’m happy I was able to get to 10 wins prior to the All-Star Game,” Matsuzaka said. “My pitching wasn’t consistent (yesterday) but I was able to hold the runners when I got into trouble. So, overall, I think it was OK.”Watching his team recapture the division lead, by a half-game margin, gives Francona, who now turns his sights to the AL All-Star squad, a cushion that makes the break that much more comfortable.”For the next three days it’s like you’re traveling. On a travel day it makes the travel better. Things like that,” he said. “We’re kind of in a fight with ourselves to see how good we can play. We can do that. We’ll take where we end up.”Sean Casey, who was thrown out at second yesterday on a ball off the wall after accomplishing a similarly dubious feat on a single to right-center in Saturday’s win over the O’s, was able to laugh about it, going 2-for-2 with 2 walks, scoring the go-ahead run, and his team having taken the win.”I don’t know,” said Casey, who raised his average to .373. “When you hit it off the wall you think you should have a double. But, I guess not in this place. But you should never have singles to right-center.”Jonathan Papelbon, entering in the ninth inning with a 2-0 lead, notched his 100th career save. But not without some adventure. The O’s had runners at first and third and a run in before Papelbon got Melvin Mora to line out to Dustin Pedroia.”I didn’t execute pitches,” Papelbon said. “I was able to go out there and kind of just will myself through that one, and sure enough collect 100, which feels really nice. It’s been the culmination of a lot of things, and 100 down and, I guess, three or 400 more to go.”Papelbon said he and his team had not been focusing on the deficit they faced over the last week.”We really haven’t been thinking about that,” he said. “You really haven’t heard much of that in this clubhouse. But I think a lot of the guys have just kind of been coming up and going to work each day, which is kind of the approach we’ve taken and sure enough at the major league break we’ve regained first place. So, it feels good.”With 65 games remaining, the Sox head into the break with a record of 57-40, tied with the 1978 club for most wins by a Sox team before the All-Star break since 1956.”It’s great,” Casey said. “I think Tampa knows that we’re not going to just go away, bottom line. They might be playing well, but that’s why you play all your 162 games.”For Mike Lowell, who will not be among the large Red Sox contingent heading to the All-Star Game, a fact that disappoints the third baseman, considers the changes in the division over the last week a testament to his team’s capabilities.”It’s showing that five games, it can turn on you in a blink of an eye,” said Lowell, who served as the designated hitter yesterday for the first time this season. “We played good for a week.
