Boston has won the first two games of four on the road against the White Sox by the same score, 10-3, and the Red Sox can win the series as well as their sixth straight game overall Saturday.
A week has made a tremendous difference for Boston (9-10), which went on the road for seven games with a 4-10 record.
"When we were starting out in that funk, we still were all positive, and we were all behind each other," said Boston outfielder Cody Ross, who was 2-for-5 with two RBIs on Friday at U.S. Cellular Field. "It's a good sign for a team like this to have each other's back and keep pulling for each other and good things will happen like the last week or so."
Chicago's losing streak is at four games after the A's took two of three from them in Oakland, but Chicago might have the advantage in the pitching matchup Saturday.
"I think the key is we've come out of the gate with a good approach on how to attack every day and guys are buying into it," Paul Konerko said. "That can get away from you as the season goes and I think that's the fight as the season goes on. It's easy to come in and not want to do the stuff that we're doing now and not want to go through that grind. The more we do it, the later it gets, if we are still in the mix -- in the divisional race -- it's easy to start thinking that, 'OK, we're in it now,' and start thinking big thoughts like that and I think that's not how we're going to be successful."
Right-hander Jake Peavy (3-0, 1.88 ERA), no stranger to ace-dom, is making his fourth start of the season and he's won the last three. The most recent, on Monday, was a complete-game, three-hit shutout against Oakland in a 4-0 victory.
Lefty Jon Lester (0-2, 6.00) meanwhile, is supposed to be Boston's ace, but has not pitched like one outside of his first start of the season, a seven-inning, one-run performance. He gave up five runs in seven innings against Minnesota his last time out, in a 6-5 Boston win and a no-decision for him Monday.
In a bright spot, Lester had a high pitch count by the middle innings but was able to find his efficiency and go seven.
"Lester was huge," catcher Jarrod Saltalamacchia said. "He gave up some runs, but he still fought, still stayed in and kept us in the ballgame where we were able to bounce back and get the win."
Red Sox: Hill recovered from Tommy John surgery
Left-handed reliever Rich Hill was added to the 25-man roster Friday, after missing almost a year following Tommy John surgery. He did not pitch in Boston's 10-3 win.
Justin Thomas, another southpaw, was optioned to Triple-A Pawtucket to make room for Hill, whose last Major League game coincidentally came against the White Sox, on June 1, 2011.
"I didn't really know at the time as far as how long it was going to take with the rehab process, but as soon as you start throwing and you start to feel like stuff is coming along and you get into the long-toss part of your program, you know things are going to go pretty smoothly and you kind of stay where you're at at every segment," Hill said. "You don't try to get too far ahead of yourself. You don't try to push the envelope with the rehab process."
White Sox: Crain placed on DL
The White Sox placed right-handed reliever Jesse Crain (left oblique strain) on the disabled list Friday, retroactive to April 21. Another righty, Dylan Axelrod, was recalled from Triple-A Charlotte.
Manager Robin Ventura is pleased with the way the White Sox have handled the expected contenders this season.
"We've already played Texas and Detroit, so they're what you would consider the 'elite,' or what the experts have picked to win their division, so we've held our own," Ventura said. "Maybe some of the hardest things are when a team is supposed to be below you and you're able to keep your intensity up. Sometimes that's hard for teams. They can get up for big teams but they can't for the other teams. Our guys have been up for every game and that's part of what I like about guys is they come in with the same attitude every day."
