BOSTON -- With two swings, Pat Burrell turned around a slow start in less than an hour.

Burrell homered to help Tampa Bay win the completion of a suspended game, then had a three-run double in the first inning of Saturday's scheduled game to lead the Rays to a 6-5 victory over the Boston Red Sox.

In the completion of the game suspended because of rain in the ninth inning Friday night, Burrell homered with two outs in the 12th to lift the Rays to a 3-1 victory.

"I figured at some point I was going to be able to drive in a run," Burrell said after the scheduled game Saturday. "I was trying to go get back to some of the things I have done in the past. I'm supposed to be a run producer. It's nice to get up and live up to the challenge."

Burrell was hitting just .185 with no homers or RBI entering the day.

"It's great. It's going to mean a lot for his confidence," Rays manager Joe Maddon said.

Evan Longoria connected in Saturday's game for Tampa Bay, which won its fifth straight.

Dustin Pedroia hit his fifth home run -- a two-run shot -- and Kevin Youkilis had a two-run homer for Boston.

Marco Scutaro hit his first long ball for the Red Sox, but made an error that led to one of five unearned runs.

James Shields (1-0) pitched 6 2/3 innings, allowing four runs and nine hits, with one walk and seven strikeouts. He improved to 4-7 in his career against the Red Sox, the most losses against any opponent.

Rafael Soriano recorded three outs for his second save of the day and fourth this season.

Clay Buchholz (1-1) worked five innings and gave up four unearned runs -- all in the first inning after center fielder Mike Cameron dropped a line drive for an error.

Burrell's bases-loaded double came one batter after Cameron dropped Carlos Pena's liner that would have ended the inning. B. J. Upton walked to fill the bases before Burrell lofted a fly ball that dropped in down the right field line.

"A big error in the game," Cameron said. "I usually don't make excuses. It kind of cut on me a little, but I make that play plenty of times. I should have made the play."

Scutaro's homer made it 4-1 in the fifth, but Upton reached on Scutaro's fielding error in the sixth and scored on John Jaso's double.

Longoria homered in the seventh to make it 6-1 before Pedroia and Youkilis connected in the bottom half.

"It's frustrating," Youkilis said of a wasted opportunity at the end of the first game and errors in the second. "We've got to do everything better."
