BOSTON -- The Boston Red Sox completed a three-game sweep of the San Diego Padres with an 8-2 victory on Thursday afternoon at Fenway Park.
Rookie right-hander Allen Webster picked up his first major league win, improving to 1-2. He went six innings, giving up two runs, five hits and four walks with four strikeouts.
"I feel each start I'm just getting a little better, a little better," Webster said. "We've been working on some things in the bullpen.
"(Craig) Breslow came in and gave me the (game) ball. I think I'm going to give it to my dad."
Red Sox manager John Farrell said, "I think with each passing start here at this level he starts to get his feet underneath him. And clearly he's a work in progress, but I thought today he made a couple of big pitches when he had to."
Padres left-hander Eric Stults took the loss, falling to 6-7. He went 4 1/3 innings, giving up four runs and nine hits with no walks, no strikeouts and a hit batter.
"Not unlike the last couple nights, the Red Sox made him work for every out," San Diego manager Bud Black said. "That was sort of the theme for this series, where they're very good two-strike hitters, they foul tough pitches off, they don't swing at balls.
"Stultsy had to work awful hard to get his outs. A couple bloops, a couple ground balls through, that's baseball. They're playing with a lot of confidence on the other side. Stultsy threw everything he had at them. It was a tough one, all the way around today."
The Red Sox got two runs in the first inning when Dustin Pedroia's double scored Jacoby Ellsbury, who reached on a single, and Shane Victorino, who doubled.
Boston added a run in the second on Brandon Snyder's home run for a 3-0 lead.
The Padres got a run in the third when they sent seven batters to the plate. Pedro Ciriaco led off with walk, moved to second when Logan Forsythe was hit by a pitch, took third on Will Venable's single and scored on Chase Headley's sacrifice fly.
Boston added a run in the fourth when Mike Napoli led off with a single, went to second on Ryan Lavarnway's two-out single and scored on Jose Iglesias' ground-rule double.
Both teams got a run in the fifth. Venable doubled and scored on Jesus Guzman's single. Napoli hit a two-out ground-rule double and then scored on Jonny Gomes' single.
Boston added two runs in the sixth off relievers Tyson Ross and Burch Smith on David Ortiz's two-run double and another in the eighth on Ellsbury's home run off Smith.
The Padres have lost six straight games, scoring two or fewer runs in each of those games.
"I think it's looked worse than it has been," Headley said of the Padres' lack of offense. "We've had some at-bats in situations where we had a chance to drive in runs and the guys hit the ball hard and it just hasn't gone in the hole for us.
"Obviously, it's disappointing when you put one, two runs up on the board for an extended period of time. I think, as a group, I don't think it's maybe as far off as it looks."
NOTES: Venable returned to the Padres' lineup after being sidelined for three games with a sore left hamstring. ... Padres SS Everth Cabrera was not activated for the series finale. He has been on the disabled list since June 17 with a strained left hamstring. He continued his minor league rehab assignment on Wednesday, going 0-for-4 with a walk and run scored for the Fort Wayne TinCaps. In two rehab games for the TinCaps, he has gone 0-for-7 with a run and a walk. ... Mark Kotsay, who served as the DH, entered the game batting .316, going 62-for-196 in his career at Fenway. It is the sixth-best average among active players. He went 0-for-4 in the game. ... Snyder hit his first home run with the Red Sox in the second inning. It was his fourth major league home run and first since May 15, 2012, for the Rangers against the Kansas City Royals. All three of his previous home runs came last season. ... Red Sox RHP Clay Buchholz threw from 90 feet on Thursday, the first time he has thrown on three consecutive days since he went on the DL on June 9. He is expected to have a no-throw day Friday and resume throwing from 105 feet after that. There is no timetable on a return to the roster for him. ... Boston SS Stephen Drew has been sidelined since Friday with tightness in his right hamstring. The Red Sox are hoping to avoid a stint on the disabled list with him. Drew could return to the lineup Saturday in Anaheim.
