The Orioles improved to a season-high 11 games over .500 after beating the AL Central-leading Tigers twice in the three-game series.

Rick Porcello (4-4) allowed six runs on nine hits, giving up a pair of homers for the third time this year.

INDIANS 6, ROYALS 3
CLEVELAND -- Justin Masterson managed to hang around for 6 1-3 innings and win for the sixth time at home, leading Cleveland over Kansas City.
Masterson (9-5) sidestepped some early trouble without giving up any runs and improved to 6-1 with a 2.29 ERA in nine starts at Progressive Field. The right-hander struck out eight while allowing two runs and nine hits.
Michael Brantley hit a pair of solo homers for the Indians, who moved within 3½ games of first-place Detroit in the AL Central. Mike Aviles drove in two runs and Michael Bourn scored twice for Cleveland.
Unable to get a hit for four innings off Luis Mendoza (2-4), Brantley homered in the fifth and the Indians added three runs in the sixth. Brantley connected again in the eighth.
RANGERS 9, ATHLETICS 4
ARLINGTON, Texas -- David Murphy had three hits and scored twice to snap out of a long slump to help Texas beat AL West-leading Oakland.
Justin Grimm (6-5) trailed when he threw his last pitch, but the Rangers scored twice in the bottom of the fifth to go ahead and make him the first Texas starter this month to get a victory.
Rangers starters had gone 17 consecutive games without a win since Derek Holland beat Kansas City on May 31. The team's previous longest such stretch was 16 in a row in 1975.
TWINS 7, WHITE SOX 4
MINNEAPOLIS -- Justin Morneau homered for the first time in almost two months and the two-run shot helped Minnesota send Chicago to its sixth loss in seven games.
Morneau's third homer of the season followed an RBI single by Josh Willingham in the sixth off Deunte Heath after ace Chris Sale's night ended after five shaky innings. Morneau last went deep on April 28. The 2006 AL MVP has three seasons of 30-plus homers.
His teammates teased him in the dugout after he rounded the bases, pretending to ignore him. So Morneau gave out a bunch of air high-fives, a light moment on a night when several Twins enjoyed fine performances. Brian Dozier reached base four times, including a three-run homer in the second against Sale (5-6).

Wilson (6-5) struck out three, walked two and allowed only two runners as far as second base en route to his fifth straight victory over the Mariners.

In the first matchup between the teams in New York since the Dodgers clinched the 1981 World Series title with a Game 6 victory at old Yankee Stadium, Ichiro Suzuki homered, drove in three runs and made a spectacular catch on the warning track for the Yankees.
New York got help from reliever Ronald Belisario's two errors on the same play in a three-run seventh.
In the night game, the Dodgers started out quickly against Phil Hughes (3-6), who allowed a season-high 10 hits in six innings.

BREWERS 3, ASTROS 1
The Brewers couldn't get anything going against Houston starter Erik Bedard as he threw a season-high 7 1-3 innings. Bedard was replaced by Hector Ambriz (1-4) with a runner on second, and Weeks greeted him with his sixth homer of the year for a 2-1 lead.
