BALTIMORE -- Facing one of baseball's premium pitchers on Monday, the Orioles continued to soar, using a key three-run homer from Steve Clevenger -- in a fourth inning that featured the first of three Oakland errors -- to hang on for a 4-2 win and a four-game sweep of the A's at Camden Yards.
The O's, who chased A's ace Sonny Gray after 5 2/3 innings, are in sole possession of the second American League Wild Card spot and have won 15 of their last 22.
"Stevie, I'm real proud of the way he went down there and did what he had to to be a good option and a contributor for us. It bodes well for him," Orioles manager Buck Showalter said of Clevenger, who was recalled from Triple-A last week after Matt Wieters' injury.
"I can't tell you how hard it is to win four games from the same team, home or away. It's hard."
MOMENTS THAT MATTERED Clevenger makes A's error costly: Clevenger's first home run as an Oriole couldn't have come at a better time. After a two-out error from Eric Sogard, who let Davis' ball go through his legs, Jonathan Schoop singled. Clevenger blasted Gray's fastball to give the O's a 3-1 lead.
"I wasn't thinking about it right away until I got back into the dugout. I think it's awesome. Playing here in Baltimore is a dream come true for me," said Clevenger, who grew up down the street from Camden Yards. "To be part of this team right now, help the team get a 'W' here in Baltimore and get it rolling -- it's great, it's an awesome experience." More >
Tillman quality: The Orioles' righty held the A's to the pair of solo shots, scattering three hits and three walks in a fine 101-pitch performance. Tillman, making his second start since rolling his left ankle, won his seventh straight decision.
"It was a grind early on, threw a lot of pitches, kind of dug myself in a hole but Caleb Joseph did an absolutely fantastic job getting me through that," said Tillman, who only felt his ankle flare up on one pitch. "Just the right mix with pitches, and we were able to grind our way through."
A's pay for miscue: The typically sure-handed Sogard was unable to get a glove on what would've been an inning-ending groundout from Davis, extending the inning that helped Baltimore secure the series sweep. Schoop followed with a base hit and Clevenger smashed an 0-2 pitch from Gray to right field for a go-ahead three-run home run. All three runs were unearned off Gray (12-5), the American League's ERA leader at 2.04.
"Especially when you have your ace on the mound," A's manager Bob Melvin said, "you want to play clean defensively."
Burns robs Davis: Davis, who already had three home runs in this series, was robbed of another when center fielder Burns made a leaping grab at the wall in dead center for the second out of the seventh inning. More >
"[Tillman was not as crisp] as he's going to be. But that's a testament to him, being able to pitch seven innings. To come out of a four-game series -- with the same club that sees your pitchers over and over again -- and come out with your bullpen on its feet. I'm pretty happy about that." -- Showalter

Left-hander Felix Doubront gets the ball in the opener.
