CHICAGO -- Another early lead turned into yet another victory for the suddenly surging Red Sox on Thursday night.
Jarrod Saltalamacchia homered twice and Kevin Youkilis hit a grand slam as the Red Sox ran their winning streak to four games with a 10-3 victory over the White Sox at U.S. Cellular Field.
Left-hander Felix Doubront, while a bit erratic, turned in a quality start to earn his first career victory. Unlike his start Saturday, when a parade of Red Sox relievers imploded vs. the Yankees, right-handed reliever Junichi Tazawa made sure this win wouldn't get away as he pitched three scoreless innings to earn his first career save.
"When you sit in this chair when you're managing, it's a special night for Felix to get his first win, Tazawa got his first save," manager Bobby Valentine said. "It's a good little memory for me and them, too."
The four-game winning streak is the Red Sox's first since Aug. 6-9 and comes on the heels of a five-game skid. All four wins have been on Boston's current seven-game road trip in which it has scored 39 runs.
"We've played some good baseball and are swinging the bats pretty good, so if you can swing the bats pretty good and get pitching performances, that's key," said Youkilis, who had three hits.
After a two-run first inning, the Red Sox took a commanding lead by scoring five runs in the third, highlighted by Youkilis' second career grand slam.
Before Youkilis' grand slam, Ryan Sweeney doubled to lead off the third inning before Dustin Pedroia and Adrian Gonzalez drew consecutive walks.
"The offense is playing extremely well," said Valentine while praising various players for drawing walks, hitting to the opposite field and being patient. "That's good offense. That's playing baseball the right way."
Saltalamacchia followed Youkilis' grand slam three pitches later with a solo shot for the first back-to-back homers by the Red Sox this season.
Saltalamacchia homered again in the fifth after Youkilis drew a two-out walk. It was Saltalamacchia's third career multihomer game, with his previous two coming back in 2007.
The Red Sox catcher now has a five-game hitting streak in which he's hitting .476 with two doubles, three homers and seven RBIs. He also has driven in at least two runs in three consecutive games.
"Salty's on fire," Valentine said.
"Right now, I guess I'm just trying to put good wood on the ball and stay consistent with what my approach is," Saltalamacchia said.
Boston scored all but one of its runs off White Sox starter Philip Humber, who followed his perfect game with one of the worst outings of his career.
Humber (1-1, 4.66 ERA) allowed a career-high nine runs on eight hits and three walks in five innings. The right-hander also threw 115 pitches after needing only 96 to complete his perfect game.
"I got a lot of pitches up and over the plate. To a team like that, they make you pay for it," Humber said. "I fell behind in the count quite a bit. Overall, it was just a bad job of executing, more than anything. We paid for it."
Although Doubront (1-0, 4.09 ERA) needed 110 pitches to get through six innings, he did enough to hold onto the big lead supplied by the offense. Aside from allowing one run to score on a groundout in the third, Doubront allowed only a first-inning RBI double to Paul Konerko and a solo homer to outfielder Dayan Viciedo in the fourth.
"I felt pretty good. Happy it's my first win," Doubront said.
Tazawa came in and got the last nine outs, allowing two runners on in both the seventh and eighth before retiring the side in order in the ninth. Tazawa now has thrown three consecutive scoreless appearances spanning six innings. As a whole, the Red Sox's bullpen has a 0.80 ERA during the four-game winning streak.
"I didn't feel like I got the save, pitching three innings, but getting nine outs ... I'm simply happy with that," Tazawa said through an interpreter.
On Friday, the Red Sox look to continue their hot play against White Sox left-hander John Danks.
"Four-game series, you want to win every series -- or at least split -- and winning the first one is a good start knowing we've got some tough pitchers coming up," Saltalamacchia said.
