OAKLAND, Calif. -- Baltimore rookie Tyler Wilson is accustomed to bouncing between the big leagues and the minors by now.
He is determined to make a case to stay put - and Monday night's outing certainly didn't hurt.
Chris Davis hit a three-run shot in the first inning for his 27th homer to back Wilson's impressive spot start, and the Orioles beat the Oakland Athletics 9-2 to stay on their roll early in the second half.
"It's just staying focused on the task at hand. There's a lot of different variables in this game that are completely out of your control," said the 25-year-old Wilson, who found out he was pitching at about 2 p.m. "I focus on the things that I can and be prepared when that phone rings, and I hope it does keep ringing. I'll do whatever it takes to be back up here."
Caleb Joseph added a two-run homer in the fourth inning off Jesse Chavez (5-11) as Baltimore won for the eighth time in 10 games.
Orioles skipper Buck Showalter earned his 1,313th career managerial victory, tying him with Hall of Famer Ned Hanlon for 31st all-time.
Adam Jones had an RBI double in the third inning for one of his three hits, while Jimmy Paredes and Joseph hit run-scoring doubles in the fifth.
A's left fielder Coco Crisp returned from the 60-day disabled list from a neck injury that sidelined him since May 20, one of six roster moves by Oakland before the game. He batted second and went 2 for 4 following a five-game rehab assignment with Class-A Stockton.
"I haven't had that many at-bats from the end of last year, no at-bats really in spring training, so when I came back the first time from elbow surgery I didn't really have the appropriate time," Crisp said. "I wanted to wait and make sure I was myself, and I was able to do that."
Wilson (2-1) pitched 7 2-3 innings in place of Chris Tillman, who has an injured left ankle. Wilson allowed two runs and six hits, struck out t hree and walked two in his second major league start and sixth appearance after being recalled from Triple-A Norfolk.
In terms of the options, Showalter quipped, "It was him and him."
Davis sent an 0-1 pitch over the wall in right-center with two outs in the opening half-inning and Baltimore built off that. Joseph matched his career high with three RBIs, and the Orioles are 17-2 when he drives in at least two runs.
"We had six homegrown guys on the field tonight," Showalter said, crediting the scouts.
Chavez's winless stretch reached three starts. The right-hander failed to reach five innings for the second time in three starts, knocked out after 3 2-3 with nine hits and six runs. He went a season-low three innings July 24 at San Francisco then five at Dodger Stadium last Wednesday.
"When he threw the ball in the middle of the plate they hit it," manager Bob Melvin said.
Felix Doubront relieved to make his Oakland debut following a trade from Toro nto on Friday. With Boston (47-59) off, the A's (47-60) fell into last place in the American League.
VOGT SNAPS FUNK
A's C Stephen Vogt doubled off the wall in right in the sixth to snap an 0-for-28 funk, his second-longest hitless stretch. He began his career 0 for 32 from April 26, 2012, to June 28, 2013. He hit an RBI double in the eighth.
The announced crowd of 11,476 was the A's smallest this year at the Coliseum.
Orioles: Tillman threw on flat ground to test the ankle and will do another workout Wednesday. If all goes well, he is likely to be slated to pitch Friday. "Still a little tender but about where we thought he'd be," Showalter said. ... Prospect RHP Parker Bridwell was placed on the DL Sunday with elbow tendinitis and will soon seek a second opinion from Dr. James Andrews in Florida.
Athletics: LHP Sean Doolittle will throw a simulated game Tuesday to test his strained shoulder. ... Switch-pitcher Pat Venditte came off the 15-day DL and was optioned to Triple-A Nashville. The A's cleared roster room for Crisp by optioning OF Jake Smolinski to Nashville. Oakland also recalled RHP Arnold Leon from Nashville, optioned RHP Dan Otero to Nashville and claimed INF/OF Danny Valencia off waivers from Toronto.
Orioles: RHP Miguel Gonzalez (9-7) goes again for his 10th victory after a loss his last time out. He looks for his third win in four starts.
Athletics: RHP Chris Bassitt (0-4) tries for his second career win after earning his first last year with the White Sox. He's 0-4 over his last five starts.
