TORONTO (AP) -

Scott Diamond is running out of answers while trying to solve his pitching problems.

Todd Redmond threw one-hit ball over five innings for his first major league win and the Toronto Blue Jays hit three home runs off Diamond Sunday to beat the slumping Twins 11-5.

"It's frustrating the way it all worked out again," said Diamond, who's allowed eight homers in his past four starts. "I'm really struggling keeping guys in the park."

Diamond (5-8) allowed six runs and eight hits in 4 2-3 innings and matched a career-high with four walks, losing for the fourth time in six starts.

"I thought they hit a lot of good pitches today," the left-hander said. "I feel my stuff is starting to get better, I'm locating down. The results just aren't there."

"Something's got to give," he said.

Twins manager Ron Gardenhire insisted Diamond's spot in the rotation is not in jeopardy.

"He'll be out there the next time unless somebody comes and tells me different," Gardenhire said.

The Blue Jays took two out of three and have not lost a series against Minnesota since May 2007. Toronto has won nine straight home series over the Twins dating to May 2005.

Aaron Hicks and Trevor Plouffe homered for the Twins, who have lost seven of eight and 12 of 16 to fall a season-worst 11 games below .500.

Rajai Davis hit a three-run homer and Jose Reyes and Colby Rasmus also connected for the Blue Jays, who won for the 10th time in 13 meetings with Minnesota.

Davis got two hits and scored three times. Rasmus also singled and doubled, drove in three runs and scored twice.

"They were whacking it pretty good," Gardenhire said. "They beat the ball around pretty good on us today."

Redmond (1-1) allowed two runs, with three walks and four strikeouts. He called his first win "a dream come true."

"I couldn't be happier," he said. "I have to give all the credit to all of the hitters today."

It was Redmond's first start of the season for Toronto and just the second of his career. The right-hander was called up from Triple-A Buffalo last week after the Blue Jays designated Chien-Ming Wang for assignment.

Twins catcher Joe Mauer said Redmond kept them off-balance with deceptive velocity.

"He has a ball that kind of got on you a little bit," Mauer said. "The ball was jumping out of his hand. It was a tough day for us offensively."

After surrendering a leadoff walk in the first, Redmond retired the next 11 batters in order. Hicks had the only hit off Redmond, a two-run homer in the fifth.

It was just the second time in six games that a Blue Jays starter has allowed two runs or fewer.

Aaron Loup and Dustin McGowan each worked one inning, Brett Cecil got two outs in the eighth and Neil Wagner got the third before Casey Janssen finished.

Toronto opened the scoring in the fourth when Davis hit a two-out double and Rasmus followed with his 16th homer.

The Twins tied it in the fifth when Hicks followed a one-out walk to Clete Thomas with his seventh homer.

The Blue Jays took the lead for good with a four-run fifth, an inning that started with Reyes hitting a leadoff homer, his fourth.

"(Diamond) kind of unraveled from there," Gardenhire said. "He just couldn't make a pitch after the home run."
