Walk-off win: Mark Trumbo's single wins it in the 10th

They used some dramatic home runs to get back in the game, but a measly single to center won it for the Orioles tonight in the series opener with Pittsburgh.

Mark Trumbo's RBI single to center with two outs scored Adam Jones in the last of the 10th as the Orioles rallied to beat Pittsburgh 6-5 at Camden Yards.

Jones came up with a one-out single in the 10th for his third hit. He then alertly tagged up and advanced to second when Manny Machado flew out to the left field wall. Trumbo then singled on a 1-0 pitch from Wade LeBlanc to end the game.

It's the Orioles' fifth walk-off win of the year and was Trumbo's eighth career walk-off hit and third of this season. The Orioles improved to 30-26 for the season, to 20-10 at home and to 5-2 in interleague games. They are 8-1 in extra-inning games.

The Orioles went to the last of the ninth down 5-3 and the first two batters tied the game off lefty Tony Watson, who was looking for his 11th save. Chris Davis singled to right and Jonathan Schoop blasted a 423-foot, game-tying, two-run homer to center. It was his second home run of the night and second in three innings. That tied it 5-5.

The Orioles hit four homers on the night, three after the seventh inning. They have hit 44 homers in their last 26 games.

Leading by one run in the top of the ninth, Pittsburgh extended the lead to 5-3 on Josh Harrison's RBI triple off Darren O'Day.

Earlier, down 4-1 against right-hander Ivan Nova, the Orioles hit back-to-back home runs to pull within a run in the last of the seventh. On the first pitch of the inning, Davis homered onto the flag court. He hit No. 13 on a changeup. It was his third homer in six games. Schoop followed with a drive down the left-field line for No. 9, his first of the night. Schoop hit an 0-1 curveball to pull the Orioles within 4-3.

The Orioles have hit back-to-back homers four times this season. Schoop has been involved in all four, one with Hyun Soo Kim and twice previously with Trey Mancini.

The Orioles had taken a 1-0 lead off Nova when Seth Smith hit their third leadoff homer of the year and his second. He drilled a Nova fastball 419 feet to straighaway center for his sixth of the year. It was Smith's fourth career leadoff homer.

But we've seen it often this year, an Orioles lead that didn't last long. This 1-0 lead did not.

Pittsburgh scored three times in the top of the second off Kevin Gausman. David Freese and Josh Bell singled to start the inning. Machado's throw went past first on Bell's infield single, advancing Freese to third.

Andrew McCutchen singled to right on an 0-2 pitch - a 97 mph fastball - to tie it 1-1. An RBI double to left center by John Jaso on a 1-2 fastball gave the Bucs the 2-1 lead. With one out, Jordy Mercer's RBI groundout made it 3-1.

Gausman settled in for a few scoreless innings before Freese's solo homer to right in the sixth made it 4-1. He hit No. 6 on a 95 mph fastball on a 3-1 pitch.

Gausman was headed for a loss before the last of the ninth. He gave up four runs and eight hits over 6 2/3 innings. He threw 113 pitches and has a season ERA of 5.86.

In the second game of this two-game series on Wednesday night, lefty Wade Miley (2-3, 2.82 ERA) faces right-hander Chad Kuhl (1-5, 6.02 ERA).

Trumbo on Jones tagging up in the 10th and his approach there: "Just get a base hit. No need to take a huge swing. That was a huge play. My approach changes if he's not there. It was a heads-up play and that's why he's really good."

Trumbo has seen growth in Schoop's offensive game: "Oh, no doubt. He is really coming into his own. The walks, especially. His plate discipline has improved to the point where he's taking pitches he may have made outs on before. And the ones he's getting to hit - look at his doubles, look at his home runs. He's a monster player and he's only getting better."

Jones on tagging up on Machado's deep drive to left: "If it gets out, then Manny won't pass me, and I just trot around the bases. If he catches it, then I'm able to tag. I tried to do it earlier on a fly ball he hit. Just knowing who's out there. (Adam) Frazier - good player, but he's a middle infielder. I've seen [him] in spring training. It's just different. Different being in the outfield, so it was just something I had seen. I picked up early in the game. It was, all right if you get a chance to go, get yourself in scoring position for Trumbo and Davis. I thought they were going to walk Trumbo, but they pitched to him, and he was able to come through with it."

Gausman was disappointed to give up run-scoring hits when ahead in the count: "Yeah, you know, I think that's a theme for me, really, this whole season is giving up way too many two-strike hits. I threw some great pitches to get to that point, but obviously, they also did a really good job with some fastballs up and just kind of didn't hit them hard, but just kind of hit them where guys weren't. Right there, you've just got to try to minimize as much as you can."

Schoop, were you thinking home run in the ninth?: "To be honest, always when I step in there I want to put a charge in the ball. I wanna drive the ball somewhere. I want to hit the ball hard somewhere. So, I was thinking that at-bat, minimize the groundball double play and I wanted to look for a good pitch to hit it hard somewhere."

Schoop's take on Jones' tag play: "It was big. That won us the game there. Tagging up on first and scored. It was big. Jones is a real good baserunner and a real good player. That's why he's the captain. He does everything right."
