Morrow (2-1) won his second straight start, allowing five hits with no walks and a season-high nine strikeouts.

TIGERS 7, YANKEES 5
NEW YORK (AP) — Miguel Cabrera homered and drove in three runs, and Drew Smyly pitched into the seventh inning for his first major league win to help Detroit snap a five-game losing streak by beating the Yankees.
Andy Dirks hit a three-run homer in the first off Freddy Garcia. Playing Delmon Young's usual position of left field, Dirks made a pair of nice defensive plays, too, running down balls that looked like extra-base hits off the bat.
Young was placed on the restricted list and will be evaluated under baseball's employee assistance program. He was arrested early Friday on a hate crime harassment charge following an encounter at his hotel in which police say he yelled anti-Semitic epithets and was intoxicated.
Smyly (1-0) gave up a leadoff single to Alex Rodriguez in the seventh. He allowed two hits and two walks in six-plus innings with seven strikeouts.
Garcia (0-2) was charged with six runs and gave up five hits in 1 2-3 innings.
RANGERS 7, RAYS 2
ARLINGTON, Texas (AP) — Colby Lewis allowed one run in six innings, Josh Hamilton had a two-run single and Texas Rangers snapped Tampa Bay's six-game winning streak.

Rays starter Jeff Niemann (1-3) gave up three runs and three walks in 5 2-3 innings. The right-hander has not pitched past the sixth inning in his four starts this season.
Hamilton went 2 for 3 and now leads the AL with 24 RBIs. Adrian Beltre added a three-run home for Texas, which improved to 16-5 and equalled the best 21-game start in club history.
RED SOX 1, WHITE SOX 0
CHICAGO (AP) — Jon Lester outdueled Jake Peavy, lifting Boston over Chicago for its sixth straight win following a miserable start to the season.
Adrian Gonzalez had an RBI single in the fourth as Lester (1-2) picked up his first win. He snapped a career-worst streak of losing five straight decisions and going eight starts without a win dating to Sept. 11. He gave up five hits and one walk, striking out seven.
The Red Sox evened their record at 10-10.
Peavy (3-1) threw a complete game for a second consecutive start for the first time in his career. He gave up four hits, struck out six and retired the last 12 batters he faced.
ANGELS 2, INDIANS 1
CLEVELAND (AP) — Dan Haren pitched eight strong innings and Albert Pujols' power drought continued as Los Angeles beat Cleveland.
Torii Hunter hit a solo homer for the Angels, who snapped a five-game losing streak. Pujols went 1 for 4 with his single during a first-inning rally giving the Angels a 1-0 lead off Jeanmar Gomez (1-1). Hunter's homer in the fourth made it 2-0.

Jack Hannahan's two-out RBI single got Cleveland within 2-1 in the fourth.
