BALTIMORE -- When the Baltimore Orioles get good starting pitching and power together, they usually find success. That formula worked again Monday night.

Adam Jones homered twice as part of a four-hit night, and Jonathan Schoop and Welington Castillo also went deep as the Orioles defeated the Oakland A's 7-3.

Jones tied a career high with the four hits, going 4-for-4. He hit a solo shot in the second inning to give Baltimore a 2-1 lead. His second homer came right after Schoop's three-run shot in the fifth.

The center fielder has been playing good baseball in the second half of the season and helping the Orioles (61-64) stay alive in the playoff race.

"I always feel strong at this time of the season," Jones said. "It's called pacing myself. I've learned how to pace myself over the years."

The first Jones homer gave the Orioles the lead for good, leaving manager Buck Showalter impressed by how the center fielder just keeps coming through at the right times.

"Adam's done that a lot, and it never goes unnoticed or unappreciated or assumed, more importantly," Showalter said. "(Schoop) obviously had a big blow there, but can't tell you how hard it is, as hard as Adam plays, as long as he plays, and then mid-to-late August you're still able to do that. That's one of the things that separates Adam."

The back-to-back homers from Schoop and Jones gave the Orioles a 6-1 lead.

For Jones, it was the second multi-homer game of the season and the 12th of his career.

Castillo went deep in the eighth.

That was enough to give starter Wade Miley (7-10) his second victory in three starts. Miley lasted six-plus innings and allowed two runs and five hits. He fanned six but struggled with his control again, walking four.

Zach Britton came on in the ninth with two on and two outs to get his 11th save of the season. He has converted 60 in a row dating to last year.

Oakland starter Chris Smith (0-3) allowed five runs (four earned) and six hits in 4 1/3 innings, including the first two homers.

Smith now has allowed 11 homers in 43 2/3 innings and is frustrated by that statistic.

"Home runs against me have been kind of the theme of the year," Smith said. "The nail in the coffin was the last one (to Schoop)."

Jed Lowrie and Boog Powell both hit solo homers for Oakland (54-71). For Powell, it was his first major league homer.

Oakland again was hurt by double plays. The A's hit into three of them, two of which ended innings and left manager Bob Melvin shaking his head a bit.

"That's been our problem for a while now," Melvin said. "We're hitting into too many double plays, not getting good balls to handle in those situations. For the last three or four days, that's been a problem for us."

The A's took a 1-0 lead in the second on a Matt Chapman double. Ryon Healy scored on the play, but Chad Pinder was nailed at the plate on a good relay from second baseman Schoop in short right.

Baltimore tied it in the bottom half on a Mark Trumbo sacrifice fly to deep left and took a 2-1 lead on the Jones solo homer in the fourth.

The A's threatened in the fifth, loading the bases with one out, but Rajai Davis grounded into a double play.

The Orioles then used the back-to-back homers from Schoop (a three-run shot) and Jones to make it 6-1 in the fifth. Schoop's homer ended Smith's night, and Jones hit his second homer of the game on the second pitch from Ryan Dull.

NOTES: Orioles 3B Manny Machado won the American League Player of the Week award. He hit .385 last week with four homers -- including a game-winning grand slam Friday -- and had 12 RBIs. ... RHP Miguel Castro returns to Baltimore on Tuesday and can come off bereavement leave the following day. ... Oakland OF Boog Powell is going to meet Orioles legend Boog Powell before Tuesday's game. They will connect at the barbecue stand the elder Powell runs at Camden Yards. ... C Bruce Maxwell should return to the Athletics' starting lineup Tuesday. He sat out Sunday after taking a shot to the face mask, and he didn't start Monday mainly because LHP Wade Miley was on the mound for Baltimore. However, Maxwell did enter as a pinch hitter in the seventh inning and remained in the game, going 0-for-2.
