Brett Anderson (5-8), who came into the game riding a 21-inning scoreless streak, lost for the first time in six starts.
Orlando Cabrera hit a one-out double and scored on Scott Hairston's sacrifice fly in the first for Oakland's only run against Chamberlain.
This was the first time in their winning streak the Yankees won by more than three runs.

Red Sox 3, Orioles 1
BOSTON (AP) - Brad Penny scattered five hits over 6 1-3 innings to help Boston snap a season-high five-game losing streak.
Penny (7-4) allowed one unearned run, striking out four and walking none for his first victory since June 17. Jonathan Papelbon pitched the ninth, earning his 25th save despite putting runners on first and third with no outs and then loading the bases for Luke Scott with one out. Scott struck out on three pitches, then Melvin Mora whiffed on a full count to end the game.
Brad Bergesen (6-5) gave up three runs, nine hits and three walks, striking out five in six innings as Baltimore lost to Boston for the 10th time in 11 games.

Rays 4, Blue Jays 2, 10 innings
TORONTO (AP) - Evan Longoria hit a two-run double in the 10th inning and Tampa Bay spoiled what could have been Roy Halladay's final start with Toronto.
Halladay, the most sought-after player available on the trade market, pitched nine innings, then the Rays scored the go-ahead run against Scott Downs (1-2).
With one out, B.J. Upton reached on a fielder's choice and went to second on a walk. Longoria followed with a double.
Matt Garza (7-7) won for the first time in four starts by allowing two runs and five hits in nine innings, his longest outing this season. J.P. Howell closed it out for his 11th save.
Halladay allowed two runs, one earned, and four hits. He struck out 10, the eighth 10-strikeout game of his career.
Consecutive sacrifice flies by Crawford and Longoria gave the Rays a 2-0 lead in the third but Toronto answered with a two-out rally in the bottom half. Marco Scutaro singled home Alex Rios and scored on Aaron's Hill's double to center.

Rangers 2, Royals 0
KANSAS CITY, Mo. (AP) - Scott Feldman outpitched Zack Greinke with eight scoreless innings and Texas extended its winning streak to five games.

Greinke (10-6) lasted seven innings, allowing one run and three hits to lower his major league-best ERA to 2.04.
Angels 6, Twins 3
ANAHEIM, Calif. (AP) - John Lackey shrugged off two solo homers by AL batting leader Joe Mauer to win his third straight start, and Robb Quinlan, Jeff Mathis and Mike Napoli all homered in Los Angeles' seventh straight victory.
The Angels won for the 11th time in their last 12 overall, and are a season-best 19 games over .500. They have gone 27-9 since June 12, and Lackey is 5-2 with a 3.24 ERA in eight starts during that stretch.
Lackey (6-4) allowed two runs and four hits over 7 2-3 innings.
Minnesota lost its fifth in six games.
Mauer, vying for his third league batting title in four seasons, was 2 for 4 and is hitting .365 with 17 homers and 53 RBIs.
All three Angels homers came off Francisco Liriano (4-10), who was charged with six runs and eight hits in 5 1-3 innings.
Indians 9, Mariners 0
SEATTLE (AP) - Travis Hafner hit a two-run homer and Ryan Garko added a three-run shot for Cleveland.
Ben Francisco and Jamey Carroll added solo homers for the Indians, who are tied with Kansas City for most losses in the AL at 58. The Indians have won consecutive games for the first time since July 3-4, thanks to their largest shutout win since May 10, 2008.
Laffey (4-2) allowed three hits, struck out seven and walked three in seven innings.
Ryan Rowland-Smith (0-1) allowed four runs and five hits in his first start for Seattle since April 10, following an elbow injury and lengthy, sputtering rehabilitation stint.

They are next-to-last in runs scored in the major leagues, ahead of only Kansas City. Even with the league's best ERA, Seattle is six games over .500.
