Manager Davey Johnson's club moved to a season-high 19 games over .500 with its series sweep of New York on Wednesday.
"I like the way everybody's playing," Johnson said.
With teams buying and selling with the July 31 non-waiver Trade Deadline around the corner, the Nationals are content with the talent they already possess. That's not to say they aren't looking to upgrade, but they completed most of the roster makeover during the offseason, when the organization added starting pitchers Edwin Jackson and Gio Gonzalez.
"Any time you make a move, you give up something," Johnson said. "Maybe it might help you this year, but it might hurt you next year. I don't believe in doing things that just help you today and aren't going to help you tomorrow."
The Brewers, who host the Nationals for a four-game set beginning on Thursday, have been on the other side of the trade whispers. Impending free-agent pitcher Zack Greinke has reportedly drawn interest from numerous teams, and a horde of scouts was on hand at Citizens Bank Park on Tuesday to watch him pitch against the Phillies.
"I really don't want to think about a different team while I'm on this team," Greinke said. "[General manager Doug Melvin] hasn't said anything to me about them trading me, so I'm assuming I'll still be here. Obviously, something could happen, but I enjoy playing here."
Jackson will oppose Yovani Gallardo in the series opener. Jackson took a tough-luck loss his last time out, allowing just one run in seven innings and striking out nine in a 4-0 loss to Atlanta on Saturday. Gallardo dropped a decision against the Reds on Saturday after yielding four runs on nine hits in 5 2/3 frames.
Nationals: Werth progressing toward early-August return
Outfielder Jayson Werth is still working his way back from a broken left wrist, and Johnson assures that he's making progress.
"Progress is coming along good," Johnson said. "I know one thing -- he didn't feel any weakness in his left wrist."
Despite Werth's swifter-than-expected recovery, the Nationals plan to maintain their timetable for his return, with their sights set on the first week in August. Werth is currently playing in rehab games for Triple-A Syracuse.
Brewers: Coaches hold meeting with 'pen
Manager Ron Roenicke and pitching coach Rick Kranitz met with members of the scuffling bullpen before Wednesday's contest against the Phillies. The group blew a five-run lead in the eighth inning on Tuesday night.
"The most important thing is to get the confidence back," Roenicke said. "However we do it. And that's why I wanted to hear from them, too. If I can do something on my end or Rick can do something on his end to either give them more confidence or maybe to help them execute pitches better, which builds confidence, then that's what we need to try to do."
The Brewers' bullpen entered Wednesday's action with a 4.76 ERA, 28th in the Major Leagues. After five scoreless innings of relief, Francisco Rodriguez blew the save in the 10th inning of Wednesday's tilt with the Phillies.
The Nationals and Brewers split six meetings last season. This is their first series of 2012.
Washington right-hander Stephen Strasburg pitched seven stellar innings on Wednesday, increasing his total for the season to 117 1/3. The Nationals have been cautious with Strasburg and plan to cap his innings.
