BALTIMORE -- Adam Jones and David Lough homered, and Kevin Gausman came up from Triple-A Norfolk to pitch seven strong innings as the Baltimore Orioles defeated the Oakland A's 6-3 on Saturday night.

Jones, Baltimore's center fielder, went 2-for-4 and added an RBI single and designated hitter Nick Markakis extended his hitting streak to 12 games when he singled home a run.

Gausman (1-1) pitched in place of Miguel Gonzalez, who went on the disabled list Friday with an oblique strain, and turned in his longest start in the majors.

He allowed a run on four hits, while striking out six and walking one for Baltimore (31-29).

Center fielder Coco Crisp had three hits, including a homer, for the A's (38-24) and Kyle Blanks added a two-run, pinch-hit single in the eighth.

Oakland starter Sonny Gray (6-2) began the night with a 3-0 record and a 1.25 ERA in five 2014 road starts. He left after walking shortstop J.J. Hardy with one out in the sixth, his shortest outing of the season.

Former Oriole Jim Johnson came on and Lough, Baltimore's left fielder, welcomed him back with a two-run homer to right, making it 6-1.

Gray was charged with five runs on four hits and four walks. He struck out seven.

The Orioles jumped in front 1-0 with two outs in the first when Jones skied a 3-1 fastball to right-center field for his ninth home run of the season.

Oakland tied it with two outs in the third. Crisp fell behind Gausman 0-2 but then lined a fastball over the wall in right.

Crisp extended his hitting streak to 11 games, and Oakland has homered in 15 straight.

Baltimore, held to one hit in the first four innings, broke a 1-1 tie with a three-run fifth.

Lough drew a one-out walk and, with catcher Caleb Joseph batting, ran on a 3-2 pitch. Joseph doubled to the gap in right-center and Lough came all the way around.

Joseph went to third on a groundout and scored on a single by Markakis. After third baseman Manny Machado walked, Jones grounded a single up the middle to score Markakis.

Protecting a 4-1 lead, the 23-year-old Gausman allowed a pair of singles to open the sixth and had Oakland's 2-4 hitters coming up.

Gausman got designated hitter John Jaso on a liner to third and, after a wild pitch advanced both runners, struck out third baseman Josh Donaldson and right fielder Brandon Moss -- the latter on a 99 mph fastball.
