WSH@DET: Ohlendorf leaves game with injury

WASHINGTON -- Long reliever Ross Ohlendorf threw a full bullpen session before Wednesday's game and said that he felt good. Manager Davey Johnson expects Ohlendorf to make a Minor League rehab start on Saturday.

Ohlendorf, who has been on the disabled list since Aug. 4 with right shoulder inflammation, said that he hopes to come off the DL when he is eligible. Johnson said that the team will wait until after his rehab appearance to make that decision.

"We'll see how he does, see how he's feeling," Johnson said. "Maybe he just goes three innings and then he has to come back and do five. And maybe he feels good enough to throw seven and come back early. The more we get him stretched out to where he can at least do five, [the better]."

In the meantime, the Nationals will use right-hander Tanner Roark, who was recalled from Triple-A Syracuse on Tuesday, as their long reliever.

Roark throws two shutout innings in MLB debut

ATL@WSH: Roark tosses two scoreless frames in debut

WASHINGTON -- As Tanner Roark made his Major League debut for the Nationals on Wednesday night, a large group of people in his hometown gathered around a flat-screen TV in a garage on a cul-de-sac.

Roark, who was called up from Triple-A Syracuse on Tuesday, said that he was sent a picture of the crowd on his phone. He estimated that more than 100 people were there.

"They hook it up from the computer and hook it to the TV," he said, smiling. "Back in Wilmington, Illinois. [I'll] give a shout-out."

Roark entered Wednesday night's game in the fifth inning after Jordan Zimmermann labored through four. The 26-year-old certainly made Wilmington proud in his debut, overcoming nerves and ignoring the crowd to allow just one hit over two scoreless innings.

"Nerves were high. First big league debut," he said. "It was great. It's exciting. Very nerve-wracking. All in all, I'll take it."

Roark also made one of the most impressive plays of the game with one on and one out in the sixth. After Braves starter Kris Medlen popped a bunt straight into the air, Roark lunged, caught the ball and threw to first base for the inning-ending double play.

"Very athletic," manager Davey Johnson said. "Made a heck of a play on that bunt."

"Yeah, I'd like to see the replay of that," Roark joked, "because it didn't feel as graceful as I'm sure it looked."

Davey just checking on Harper during exchange

ATL@WSH: Harper, Johnson exchange words in dugout

WASHINGTON -- Bryce Harper hustles on every ball he puts in play, whether it's a double down the line or a routine ground ball. So when he merely jogged to first base after flying out to left field in the seventh inning, manager Davey Johnson was worried.

"I was concerned about his leg bothering him because he didn't round the base," Johnson said, referring to the left knee that caused Harper to miss 31 games earlier this season. "That was all that was about."

Harper and Johnson were seen arguing in the dugout.

"He was checking on my leg and seeing how I felt," Harper said, adding that the exchange wasn't as animated as it looked. "I just told him that I felt fine and I didn't want him to take me out of the game. I wanted to stay in the game."

Added Johnson: "It wasn't bad enough to come out of the game."

Davey says Nationals not looking to retaliate

ATL@WSH: Harper on hit-by-pitch by Teheran

WASHINGTON -- Less than 24 hours after Braves starter Julio Teheran hit Bryce Harper with a fastball, emptying both benches and bullpens in a near fracas, Nationals manager Davey Johnson said that he didn't expect his team to retaliate in Wednesday's series finale.

"No," Johnson said, "it's just baseball as usual."

Harper hit a home run in the third inning before being hit by Teheran's pitch in the fifth. The ball hit Harper in the side of the right thigh, prompting the 20-year-old to yell and point at Teheran while walking to first base. Braves catcher Brian McCann, who had to be restrained by home-plate umpire Joe West, said that Harper circled the bases too slowly after his homer.

"He's got a bad leg," Johnson joked on Wednesday.

The Nationals' skipper said that he could feel a heightened intensity in the dugout after the ordeal and attributed it, in part, to the rivalry between the two teams and the Braves' 11-game win streak at the time. The teams' official Twitter accounts even got involved, though Johnson said that he didn't pay attention to their exchange.

"No, I avoid Twitter like the plague. Facebook, I avoid it," Johnson said. "I usually say what's on my mind, and a lot of times, I already say too much. I'm too candid. Everybody tweets, I guess, but not me."

Worth noting

Lucas Giolito, the Nationals' No. 2 prospect, picked up his first professional win on Wednesday, allowing one run on five hits over five innings for Washington's affiliate in the Gulf Coast League. Giolito, who was the team's top Draft choice in 2012, has made seven starts since returning from Tommy John surgery. He is 1-1 with a 3.57 ERA.
