OAKLAND Josh Willingham drove in two runs against his former team, Joe Mauer hit a two-run single, and the Minnesota Twins snapped the A's four-game winning streak with a 7-2 victory Monday night.
Brian Duensing (3-8) struck out seven and walked one in six innings to win for the first time in three starts after consecutive losses, helping the Twins bounce back from a three-game weekend sweep at Seattle to begin a 10-game trip.
Darin Mastroianni had an RBI single and added a sacrifice fly in the eighth, and No. 9 hitter Pedro Florimon joined Willingham and Mauer with three hits apiece for Minnesota, which went 4 for 11 with runners in scoring position a day after missing in all 10 such chances in the series finale at Seattle.
The A's had won their previous five home games and lost for just the 11th time in 37 home games since June 6.
A's starter Brandon McCarthy (6-5) surrendered three straight one-out hits in the first, including Willingham's RBI double.
Trevor Plouffe also drew a bases-loaded walk as the Twins took a 2-0 lead.
McCarthy's night was done after he gave up Willingham's third hit, an infield single in the fourth. Travis Blackley pitched 5 2/3 innings of relief.
McCarthy, Oakland's Opening Day starter, was knocked out after 3 1/3 innings for his shortest outing since also going 3 1/3 on Aug. 12 last year in a 9-1 loss to Texas.
His 10 hits allowed matched his second-highest total of the season, and he was tagged for a season-high six runs.
Josh Donaldson hit a run-scoring double, and Josh Reddick added an RBI groundout for the A's, who had won four games in a row to move a season high-tying 10 games over .500 but they missed going 11 games over for the first time since finishing the 2006 season 93-69.
That team was the last to make the playoffs, reaching the American League Championship Series before being swept in four games by the Tigers.
Derek Norris had two hits to lead the A's, who couldn't do much against the left-handed Duensing. He allowed two runs and five hits.
Former Oakland star Willingham received scattered boos from the small announced crowd of 10,274 when he came to the plate in the first. Most of those fans were gone by the late innings with the A's trailing.
Note The A's announced they acquired veteran shortstop Stephen Drew from the Arizona Diamondbacks for minor league infielder Sean Jamieson.
The trade reunites Drew with former Diamondbacks manager Bob Melvin in his first full season as A's skipper.
"It'll be refreshing and a new start," Drew said. "It's a good feeling to go over there and still be competing (for the postseason)."
Drew, 29, is expected to join Oakland in time to play the middle game of the series against the Twins tonight. He recently returned after being sidelined for nearly a year with a fractured right ankle. He sat out 137 games in all.
The 29-year-old Drew is batting .193 with two home runs and 12 RBIs in 40 games since his first game back June 27.
