BALTIMORE -- As Orioles manager Buck Showalter likes to say: delayed, not denied.
Mark Trumbo's 12th-inning walkoff homer kept the Orioles right in the thick of the American League Wild Card race Friday night, leading Baltimore to a 3-2, 12-inning win over the D-backs in a four-hour series opener.
Backed by six scoreless innings from the bullpen, the Orioles snapped a four-game losing streak and stayed one-half game behind Detroit for the AL's second Wild Card spot. It marked just their third victory in their last nine home games.
"Momentum is your next game, it really is. I'm glad our guys feel good about themselves for one night, they've been frustrated," Showalter said. "They've earned the right to play these meaningful games and I'm happy for them. What it means, like I said, momentum is usually your next starting pitcher."

Trumbo's blast, which came off Arizona reliever Matt Koch, led off the bottom of the 12th and was his 44th homer on the year. It also capped the O's rally effort, as homers by both Pedro Álvarez and Matt Wieters saw the Orioles scored three unanswered runs.
According to Statcast™, Trumbo's walkoff home run had an estimated distance of 408 feet with an exit velocity of 107 mph and a 20-degree launch angle.

Alvarez put the Orioles on the board with a two-out homer in the eighth off reliever Enrique Burgos with Wieters connecting for a game-tying solo blast in the ninth.

"All losses are tough, we've had a lot of them this year, so they've all been tough," D-backs manager Chip Hale said. "They did a great job of battling back and tying the game and we did a great job of stopping them from winning the game a couple of times."

Fresh off a four-game sweep by the Red Sox, the O's were held scoreless by D-backs righty Shelby Miller, who entered the game 2-12 with a 6.90 ERA. Miller allowed three hits and three walks over his six innings, turning in his first scoreless outing of the season.
Baltimore starter Yovani Gallardo also went six innings, allowing two runs -- on doubles by Jake Lamb and Jean Segura.

MOMENTS THAT MATTERED
Wieters comes up clutch: Baltimore was handcuffed by Miller over the first six innings, but Alvarez and Wieters managed to even things up. Wieters' leadoff blast in the ninth off Daniel Hudson forced the game into extra innings and was one of several notable clutch hits for the catcher this season. He also singled to start the 11th.
"Just trying to get a good pitch to hit," Wieters said. "Got to 3-0, then he was able to even up to 3-2. I still knew he was going to try and come with the strikes, so it's just being ready to go." More >

That's more like it: Miller has largely been a disappointment this season, his first in Arizona. But he was in control in this one, navigating through jams and posting his best start of the year. The three hits allowed are the fewest he's allowed in a start that has lasted more than two innings.
"That's a real step forward for him," Hale said. "He located the ball better, he just did a nice job." More >

Gallardo does his job: Coming off a 3 1/3-inning outing against Tampa Bay, Gallardo rebounded for his first quality start since Aug. 31. Working on eight days' rest, the righty struck out five and allowed two runs on six hits and two walks.

"You never want to have a start in that way, giving up a run in the first, giving up a run in each of the first two innings," Gallardo said. "It's going to happen. For myself, the thing to myself is to just leave it right there, to not allow any more runs and give the guys a chance to swing the bat and it happened. I've just got to find a way to put zeros up, make some pitches and get out of some jams when I have to."

D-backs' defense backs Miller: Several nice defensive plays helped Miller preserve an early lead. In the first, Chris Davis hit a towering fly ball to right, but Yasmany Tomás made a nice jumping grab at the wall to rob the Baltimore first baseman of what likely would have been a three-run homer.
"Yas made a pretty good play on it. I think it possibly could've been gone if he wasn't there," Miller said. "He made extremely good plays tonight for me; a lot of guys in the outfield did."

That wasn't all, however, as Arizona shortstop Chris Owings made a tremendous off-balance throw from deep in the hole to rob Adam Jones of an infield hit for the final out of the fifth. After Miller left, left fielder Sócrates Brito, a defensive replacement, gunned down J.J. Hardy at the plate for the second out of the ninth, preserving a 2-2 tie. More >

QUOTABLE
"We all know what math is involved here. But if you dwell on that, you hope, this time of year you can't expect anything … you like being in this arena. That's why you do this. The players, that's what separates them. They don't want to watch the highlights on Sportscenter. They want to be a part of them. And that's the difference." -- Showalter, on his club's playoff push
"That's the million-dollar question. I hope so. I hope so. We're giving it everything we have and obviously we're gonna have to keep it going. We know what we have to do and we've got the guys to do it." -- Trumbo, on if Friday's win can turn the tide for the O's
SOUND SMART WITH YOUR FRIENDS
Orioles reliever Oliver Drake, who had a quick 1-2-3 12th inning, picked up his first Major League win.
REPLAY REVIEW
The Orioles lost their manager's challenge on the second out in the ninth, as they challenged that Hardy was safe on Britos' throw from left field as he tried to score on Jones' single. The review, which took two minutes, would have ended the game had the call been reversed.

WHAT'S NEXT
D-backs:Robbie Ray makes his first career start against the Orioles when the series continues on Saturday at 4:05 p.m. MST. Ray (8-13, 4.66 ERA) is 1-1 with a 7.29 ERA in four starts this month. However, the left-hander continues to pile up strikeouts. He has 210 this season, averaging 11.39 per nine innings.
Orioles:Wade Miley will get the ball for the Orioles on Saturday at home against Arizona at 7:05 p.m. ET. The lefty, who left Sunday's start after four innings with a mild back strain, had allowed just one hit when he exited. Miley, who will go on the paternity list after Sunday's game, is 8-13 with a 5.65 ERA.
