Gleyber Torres hits three home runs as Yankees sweep doubleheader against Orioles

J.A. Happ wasn't expecting Aaron Boone's sixth-inning mound visit.

And the veteran lefty couldn't imagine he was about to exit Wednesday's first game at Yankee Stadium after just 64 pitches.

"I just wanted to make sure he remembered we had a doubleheader today," Happ said of the quick conversation with his manager.

Ahead by two runs, the Yankees had a very well-rested bullpen, due to consecutive rainouts on Monday and Tuesday.

"The four guys that came in were about as nasty as I've seen all year," Happ said after Adam Ottavino, Tommy Kahnle, Zack Britton and Aroldis Chapman closed out a 5-3 victory against the last-place Orioles.

"At the same time, I still would have rather stayed in there."

Somehow, Orioles starter David Hess lasted a full six innings despite yielding four solo home runs – two by Gleyber Torres.

Torres homered again in the nightcap, another solo shot that boosted the Yankees to a 3-1 win and a doubleheader sweep before 41,138 fans.

Domingo German had another top flight start, yielding one run over seven innings and improving his record to 8-1.

Luke Voit broke out of his recent slide with an RBI double in the third and an RBI single in the seventh.

In outdueling Andrew Cashner (4-2), German survived a pivotal seventh-inning spot.

After defensive replacement Brett Gardner made a sliding catch in left field of a Hanser Alberto sinking liner, a German wild pitch moved runners to second and third.

German issued a walk to load the bases but got Joey Rickard on a force play for the third out.

Luis Cessa helped out by pitching a scoreless eighth and Chapman recorded his second save of the day.

In the opening game, Gary Sanchez hit a monstrous first-inning shot that sailed over the Yankees bullpen in right-center and Cameron Maybin homered to right in the second inning, his first as a Yankee.

And that powerful beginning instantly put Boone at ease.

"It felt a little odd to me at first," Boone said of the 3:05 p.m. start before just a smattering of fans.

Monday's rainout necessitated Wednesday's single-admission doubleheader. Tuesday's rainout will be made up as part of a day-night doubleheader on Aug. 12.

"I thought the energy and the focus was really good and they performed," Boone said. "(It was) a weird start, sparse crowd after having a couple days off.

"(I) really like the way the guys came out."
