Nats not ready to bring up Ohlendorf after rehab start

WASHINGTON -- Nationals right-hander Ross Ohlendorf, who is on the disabled list because of an inflamed right shoulder, pitched three innings and threw 63 pitches for Triple-A Syracuse on Saturday. He allowed one run on five hits while striking out four.

The Nationals were not satisfied with what they saw against the Pawtucket Red Sox, so Ohlendorf will get another Minor League start after all.

"He is not where he needs to be. He needs one more start," manager Davey Johnson said.

Once he's back with the Nationals, Ohlendorf most likely will go back to the bullpen and then replace right-hander Taylor Jordan in the rotation.

Jordan is on an innings limit and has two more starts, after Saturday's game against the Phillies, before his season comes to an end. Jordan had Tommy John surgery in 2011 and is on the same limitation that affected Stephen Strasburg last year.

If Ohlendorf isn't ready to go, right-hander Tanner Roark will be the fifth starter. He was a starter and long reliever while pitching for Syracuse this year, going 9-3 with a 3.15 ERA.

Roark proud to notch first Major League win

WASHINGTON -- Reliever Tanner Roark picked up his first Major League victory as the Nationals defeated the Phillies, 8-5, at Nationals Park on Saturday night.

Roark pitched two scoreless innings and needed only 12 pitches to get the job done. When he left the game, the Nationals were down, 4-3, but scored five runs in the seventh inning, highlighted by a two-run home run by Jayson Werth.

"It felt great. A good come-from-behind win. It was a great team effort. The bats came alive and it was awesome to watch," Roark said.

After the game, Roark said he was going to give the game ball to his parents, Toby and Jodi Roark, who live in Illinois.

"They have an old trophy case for all my brothers and sisters," he said. "I'm going to give it to them, and I'm sure they are going to be pretty ecstatic about it."

Roark made his Major League debut this past Wednesday against the Braves, and he said he was nearly as nervous on Saturday against the Phillies.

"It wasn't as bad. But it was definitely still there," Roark said. "I still had the nerves and still had the excitement and everything like that."

Zimmermann, Desmond consider long-term future

WASHINGTON -- Nationals shortstop Ian Desmond and right-hander Jordan Zimmermann are having solid seasons for the Nationals. Entering Saturday's game, Desmond is hitting .273 with 16 home runs, 54 RBIs and 15 stolen bases, while Zimmermann leads the team in victories (13) with a respectable 3.10 ERA.

But neither player is close to getting a contract extension. Zimmermann and the Nationals were talking about going beyond a one-year deal during this past offseason and Spring Training, but they never came close to agreeing to terms. Zimmermann said he didn't want to talk about a contract during the season, but he is willing to talk after the season comes to an end.

Zimmermann, 27, was arbitration eligible last offseason, but later agreed to a one-year deal worth $5.35 million with Washington.

"We worked on stuff this offseason, but nothing really worked out," Zimmermann said. "I just didn't want to talk about it during the season. So I said if we can't reach an agreement, we'll wait until after the season, so that's what we are going to do.

"I like it here. Obviously, it's the only place that I know. It would be nice to stay long term, but it has to be something fair. I'm just not going to do a team-friendly deal just to stay here long term. If it's a fair deal, then obviously, we'll definitely think about it. But I'm not going to give a huge team discount. Just something fair is all I ask."

Desmond, 27, sounded as if he was not in a rush to get an extension. He pointed out that he will be arbitration eligible a few more years before becoming a free agent in 2016.

"It's a win-win all around. I've been [with the Nationals] my whole career," Desmond said. "Do I want to stay here? Yes. But only time will tell when that bridge comes in front of us.

"It's not in my hands. Obviously, if the situation arises and it works out for both sides, we'll cross that bridge when we get there."
