Alex Rodriguez suffered a broken left hand after being hit by a Felix Hernandez pitch as Seattle Mariners defeated the New York Yankees.
Rodriguez was hit with an 88mph ball which left him with a non-displaced fracture of his hand - with the team unable to give any indication when he'll be healed up to play again.
Hernandez (9-5) allowed a home run to Curtis Granderson in the first inning - the first long ball he's allowed in his last eight starts. But Hernandez pitched out of trouble in the later innings to extend his longest win streak since he won nine straight in 2010, his Cy Young season.
Hernandez also hit Derek Jeter and former teammate Ichiro Suzuki in 7 1-3 innings of four-hit ball.
Michael Saunders hit his 10th homer of the season for Seattle in the first inning and one-time Yankees prospect Jesus Montero added an RBI single in the third that proved to be enough support for Hernandez.
Meanwhile the Chicago White Sox were 11-4 winners against Minnesota in the American League as Adam Dunn crushed his Majors-leading 30th homer, a game-tying two-run shot in the seventh.
That set up a nine-run outburst over their final two at-bats. Dunn (3-for-5) and Paul Konerko (4-for-4) each finished a triple shy of the cycle as Josh Willingham homered twice in defeat.
Oakland were 7-2 winners against Toronto as Travis Blackley fanned a career-high eight batters in seven innings.
Derek Norris' two-run jack set an early tone as the A's won their sixth straight.
Yoenis Cespedes also aided a five-run seventh that iced it, while Travis Snider and J.P. Arencibia homered in the loss.
Brooks Conrad gave the Tampa Bay Rays a lead in the fifth inning with his two-run homer before Jeremy Hellickson and the Tampa Bay bullpen did the rest for a 3-1 win over Baltimore.
Hellickson allowed one run on just three hits in 6 1/3 innings. O's starter Wei-Yin Chen was solid, allowing three runs in 6 2/3 innings.
Boston beat Texas 2-1, Cleveland edged out Detroit 3-2 and Kansas City defeated Los Angeles Angels 4-1.
The St Louis Cardinals ended an eight-game losing streak to the Los Angeles Dodgers as Adam Wainwright threw 7 1/3 strong innings.
Wainwright added two RBIs as LA's Clayton Kershaw gave up eight earned runs, including six in the sixth inning of this National League fixture.
Cincinnati defeated Houston 4-2 as Drew Stubbs tagged Francisco Cordero, in his first Astros save chance, with a decisive homer in the ninth.
Xavier Paul had three hits in his first Reds start to back Mike Leake (8 IP). Justin Maxwell hit a two-run homer for Houston.
Washington beat New York Mets 5-2 after Adam LaRoche's two-run homer keyed a four-run Washington sixth to end a pitchers' duel between Gio Gonzalez and R.A. Dickey which was tied at that point.
That gave Gio more than enough support as he two-hit the Mets for seven innings in his 13th win of the year.
Atlanta defeated Miami 4-3, Philadelphia edged Milwaukee 7-6, the Chicago Cubs were 5-1 winners over Pittsburgh, Arizona were 6-2 winners over Colorado and San Francisco edged San Diego 3-2.
