OAKLAND, Calif. — Mark Trumbo hit a grand slam for his major league-leading 32nd homer and drove in five runs as the Orioles beat the Athletics 9-6 Thursday to avoid a four-game sweep.
The Orioles had been shut out for 17 straight innings and lost their lead in the AL East following three consecutive one-run losses before Trumbo sparked them.
The All-Star slugger hit an RBI single in a three-run fourth, then connected the next inning for his third career grand slam.
Chris Tillman (15-4) allowed two runs over seven innings for his first victory since July 21. He is Baltimore's first 15-game winner since Bud Norris and Wei-Yin Chen in 2014.
Zach Britton retired three batters for his AL-leading 35th save this season and his 37th consecutive dating to last season. The A's loaded the bases in the ninth after a replay overturn before Britton got Danny Valencia to ground out to end it.
