Orioles 6, Rangers 5; Rangers 7, Orioles 3: Host Baltimore became the first AL team to open a game with three straight home runs and hit two more later, all off Colby Lewis, in the first game of a doubleheader.
In the second game, Josh Hamilton hit his major league-leading 15th homer and Derek Holland pitched six innings of four-hit ball as Texas worked a split.
In the opener, Ryan Flaherty, J.J. Hardy and Nick Markakis began the bottom of the first inning with homers.The last team to homer in its first three at-bats was the Milwaukee Brewers on Sept. 9, 2007. Hardy was also the middle man in that assault. It had happened twice previously, both in the National League.
After the first-inning homers, Lewis retired his next 18 batters before Adam Jones homered leading off the seventh. Lewis walked Matt Wieters, and Wilson Betemit hit a drive to right for a 6-1 lead.
Yankees 5, Rays 3: CC Sabathia outpitched David Price for the first time in six career matchups between the All-Star lefties and Robinson Cano and Curtis Granderson homered as host New York beat Tampa Bay.
The Yankees overcame a pair of early errors by third baseman Eduardo Nunez to take the series and send Tampa Bay to its fourth loss in five games.
Sabathia (5-0) struck out 10, punctuating his outing by fanning B.J. Upton with two runners on base to end the seventh inning.
Indians 8, Red Sox 3: Embattled starter Josh Beckett did nothing to help restore his reputation, getting booed off the field at Fenway Park in the third inning.
Jack Hannahan hit a two-run homer and Jason Kipnis had a solo shot off Beckett, who was scratched from his last scheduled start with a sore lat muscle in his back.
His return to the rotation couldn't have gone much worse. Beckett (2-4) gave up seven runs on seven hits and walked two in 21⁄3 innings as Cleveland built a 7-1 lead.
Michael Brantley went 4-for-5 with two RBI for the Indians. Derek Lowe (5-1) pitched six effective innings against his former team.
Nationals 4, Pirates 2: Stephen Strasburg struck out a season-high 13 over six innings and Washington snapped a three-game losing streak.
Roger Bernadina and Adam LaRoche both homered in the sixth off Pittsburgh's Kevin Correia (1-3) to erase a two-run deficit. Henry Rodriguez pitched the ninth for his seventh save.
Strasburg improved to 3-0 while trimming his ERA to 1.64 by overpowering the punchless Pirates. The right-hander gave up two runs, one earned, on five hits.
