"We're just not getting it done and winning ballgames," he said. "We're either not scoring runs or giving up too many runs."
Friday night it was the first of the two problems as the team accumulated eight hits, but pushed just one runner across the plate in a 5-1 loss to Washington.
The early struggles contrast with preseason expectations, which were that the Brewers were ready to be a contender out of the gate in 2008.
"That's something that every team deals with," Yost said. "It's not just something that we're dealing with. You definitely have to learn how to handle it and deal with it. I think they learned a lot last year going through what they went through."
With a young roster, Yost said his team just needs to continue playing baseball the way it's capable of playing, instead of pressing or allowing themselves to stress over the situation.
"You have to come to the park every day ready to give everything you've got, but you have to do it in a relaxed fashion," Yost said. "Right now, they're all a bunch of young kids that really want to win, and they give everything they have when they step on the field."
With three games remaining against the last-place Nationals, the Brewers will try to head home with some momentum. The news is good when they get back -- the team is following three consecutive road series with three at home, starting Tuesday against Atlanta.
Yost said he's looking for his guys to develop consistency and momentum at the plate, something that's hard to do when they run into a strong pitching performance like Friday night's from Odalis Perez and the Nationals bullpen.
"There's no one thing you can do to be more consistent," Yost said. "We'll start to get a little streak going offensively, then we'll run into a well-pitched game like we did Friday."
