MILWAUKEE -- In need of an extra man in the bullpen, the Nationals placed right-hander Ross Ohlendorf on the 15-day disabled list, retroactive to Aug. 1, with right shoulder inflammation and recalled left-hander Xavier Cedeno from Triple-A Syracuse.
Ohlendorf has had shoulder problems since Thursday against the Tigers. On that day, his fastball was clocked as high as 85 miles an hour. Usually , Ohlendorf's fastball is clocked in the low-to-mid 90s.
Ohlendorf said he needed a couple more days of rest because his arm hasn't recovered from his emergency start against the Mets on July 26. In that game, Ohlendorf threw 114 pitches, a season high.
Because Ohlendorf hasn't been able to pitch, the Nationals had only six relievers available in the first two games against the Brewers. Cedeno will be the seventh man on Sunday.
"I just needed a couple of more days. … It's nothing that I'm really worried about. I wish that I didn't need to go on the DL," Ohlendorf said. "I think this will work out best for everybody. It would be tough to have six guys in the bullpen while they are waiting for me to be ready."
Cedeno, 26, joins the Nationals for a third stint since being claimed off waivers from the Astros on April 23. He learned of his promotion to the big leagues on Saturday night. As a member of the Nationals, Cedeno hasn't allowed a run in 1 1/3 innings and has struck out one batter.
Nats understand importance of Braves series
MILWAUKEE -- Entering Sunday's action, the Nationals were 11 1/2 games behind the Braves in the National League East and the two clubs meet in an important three-game series at Nationals Park starting Monday night. The Nationals know how important it is to put a dent into the Braves' lead.
"This series is very important, but at the same time, we have to go into it like any other series and just try to win one game at a time," third baseman Ryan Zimmerman said. "We have to take care of our business and win games. If they continue to win, it doesn't matter what we do. We just have to take care of business on our end and hope at some point they lose a few in a row and we can get back into [the race]."
Even though the Braves aren't getting great offensive production from the Upton brothers -- B.J. and Justin -- Zimmerman is not surprised to see the Braves in first place. Zimmerman pointed out that they have a great pitching staff.
"If you look at any team, including us last year, pitching is what wins," Zimmerman said. "I think Pittsburgh is showing you that right now. Any team that is 15, 20 games over .500, it's because they can pitch and play good defense. Obviously, hitting is a big part of the game, but you can get by with not scoring a lot of runs. You can't get by if you give up a lot of runs. The Braves pitch the ball well and their starters are good, their bullpen is one of the best in the league. They are a good team."
The Nationals have yet to go on a significant winning streak. It doesn't help that they are near the bottom in the NL offensively and defensively. The pitching staff has been solid. Entering Sunday's action, it has a 3.70 ERA, which ranks 11th in the Major Leagues.
"We haven't figured it out for longer than a week at a time," first baseman Adam LaRoche said. "You don't want to say you are out of [winning the division] until you are mathematically eliminated. You are not going to give up on winning the division. But ... when you lose ground, it makes it harder. It's getting down to the point where [11 1/2] games are a lot. We do have some ball left, but 's going to take some really good ball."
