BALTIMORE -- Rookie left-hander Brett Oberholtzer allowed three hits over seven innings to earn his first major league win, Jason Castro hit a grand slam and the Houston Astros beat the Baltimore Orioles 11-0 Wednesday night.
Matt Dominguez homered and had a career-high four hits for the Astros, who built a 9-0 lead in the fourth inning and coasted to their most lopsided victory of the season.
Oberholtzer (1-0) started after Erik Bedard was scratched with a sore shoulder. Making his fourth appearance and first start in the big leagues, Oberholtzer struck out six, walked none and did not let a runner get past first base.
Miguel Gonzalez (8-5) yielded a career-high nine runs, four earned, in 3 2-3 innings.
Hours before the first pitch, the Astros traded pitcher Bud Norris to the Orioles for outfielder L.J. Hoes and a minor league prospect. Hoes switched from the Baltimore starting lineup to batting second for Houston and went 0 for 5.
TIGERS 11, NATIONALS 1
The AL Central-leading Tigers swept the two-game series. They have won five straight, the latest victory coming while star Miguel Cabrera was out of the lineup, a day after aggravating an injury.
Justin Verlander (11-8) shook off a shaky start by giving up one run, four hits and five walks while striking out six in six innings.
Gio Gonzalez (7-4) gave up 10 runs -- one short of his career high -- and 11 hits -- the most of his career -- over 3 1-3 innings.
BLUE JAYS 5, ATHLETICS 2, 10 INNINGS
Bautista doubled off Jesse Chavez (2-3). Rookie catcher Stephen Vogt's second costly passed ball of the game allowed Jose Reyes to advance after a leadoff infield single, and Reyes scored on Bautista's hit.
RANGERS 2, ANGELS 1
ARLINGTON, Texas -- Adrian Beltre led off the bottom of the ninth for Texas with a home run to beat the Los Angeles Angels, completing a three-game series sweep in which the Rangers won each on game-ending homers.
Beltre hit his 23rd homer, connecting off Michael Kohn (1-1).
Rangers closer Joe Nathan (3-1) struck out two and walked one in the top of the ninth to win for the second night in a row.
INDIANS 6, WHITE SOX 5, 10 INNINGS
Santana hit a 3-2 pitch from Dylan Axelrod (3-7) into the right field seats for Cleveland's ninth walkoff win of the season.
DIAMONDBACKS 7, RAYS 0
Miley (8-8) won for the fourth time in five starts. He struck out eight in 6 1-3 innings and walked five.
Jeremy Hellickson (10-4) gave up four runs and seven hits in 4 1-3 innings.
