OAKLAND, Calif. -- Guillermo Moscoso got off to another rocky start. This time, the rookie right-hander didn't let it get out of control.
Hideki Matsui singled twice and reached five times for the A's, who snapped a three-game losing streak to the Twins. Matsui is batting a major league-best .473 since the All-Star break.
Moscoso (4-5) allowed two runs -- both coming in the first two frames -- and seven hits in 6 1/3 innings. Moscoso's second win in his last 11 outings reminded manager Bob Melvin of the pitcher who won his first two starts of the year.
"I think he was tired of seeing some of the results he was getting the last couple of games, getting behind in counts and being more predictable than he should be," Melvin said. "It was good to see. He went out there with a lot of focus, especially in the middle innings."
"It's definitely a strange position to be in, but from what I hear I'm here and I'm staying here," Harden said. "I'm happy to be an 'A.' ... It's definitely a strange position to be in."
The 27-year-old Moscoso gave up 11 earned runs over his previous 9 2/3 innings, but was much better against Minnesota. He retired 14 of 16 during one stretch and left with a 7-2 lead.
"They were getting me pretty early, so I started mixing up all those pitches and tried to get ahead in the count," Moscoso said. "That's what I did after the second inning and that was the key through the sixth."
"One of the worst defensive nights," Twins manager Ron Gardenhire said. "Balls can't go rolling through the infield -- it's not acceptable around here, yet it happened. A terrible defensive game and there you have it."
Nick Blackburn (7-8) struggled again for Minnesota, charged with seven runs, six earned, and 10 hits in 4 1/3 innings. The right-hander walked five and struck out two.
Blackburn also started the Twins' 20-6 loss to Texas last Monday and was tagged for nine runs in 2 2/3 innings.
Cliff Pennington extended his career-high hitting streak to 14 games and scored the go-ahead run in the second for Oakland. The A's have at least eight hits in 15 consecutive games, matching their longest such streak in Oakland history set in 1980.
Matsui, Oakland's biggest offseason acquisition, hit .209 in the first half but has been on a tear since the break. He walked in his first two plate appearances, singled and scored in the fifth and reached on a fielder's choice in the sixth.
Oakland pushed across two runs in the bottom half to take the lead for good. Jemile Weeks drove in Pennington with a triple, making it 3-2.
The A's placed RHP Michael Wuertz on the 15-day disabled list with a thumb injury and recalled LHP Jerry Blevins from Triple-A Sacramento. ... RF David DeJesus was pulled in the third inning with what the A's announced as right thumb soreness. ... Twins star Joe Mauer went into the game with a career .324 average at the Coliseum but went 0 for 4.
