He's not the only one.
"I've seen Zack like this during seasons where you know he goes out there and you say he's a good pitcher, but he's not what he can be," Brewers manager Ron Roenicke said. "And that's what I'm saying right now. He's a good pitcher, but he's not the Cy Young Zack Greinke right now. And I guess that's what I'm kind of saying when I'm saying I still think there's something kind of missing."
Roenicke knows exactly what's missing from his ace's repertoire, and he hopes his pitcher is better on Wednesday against Jason Marquis and the Nationals.
"You know the breaking stuff is not quite there," Roenicke said. "When he's right, the breaking stuff is unhittable -- and I don't see that right now."
In his last start, Greinke was charged with four runs on eight hits in six innings against the Rockies. He surrendered a two-run homer to the opposing pitcher, but said he was working with his best fastball.
"That's probably the best I've pitched so far. I felt strong, too," Greinke said. "I felt good the whole time."
As for Marquis, he started Friday's 17-5 victory over the Orioles, but didn't figure in the decision. At 5-1, he leads the team in wins, but has been ineffective in two of his four May starts. Despite the inconsistent month, he has compiled a 2-1 record this month, to go with a 6.26 ERA.
Nationals: Ankiel activated
The Nationals activated center fielder Rick Ankiel from the disabled list on Tuesday, after he missed 19 games with a sore right wrist. He went 0-for-2.
After going a combined 1-for-18 with runners in scoring position in a 2-1 loss at Baltimore and an 11-3 loss at Milwaukee, the Nats went 4-for-11 with runners in scoring position on Tuesday.
Brewers: Morgan close to returning
Nyjer Morgan, on the disabled list with a fractured left middle finger, led off every inning of an exhibition game at extended Spring Training in Phoenix on Tuesday, and went 1-for-4. He is expected to play in one more game before returning to the big leagues on Friday.
According to the Elias Sports Bureau, Corey Hart was only the second player in the last 50 seasons to hit at least three home runs and drive in at least seven runs from the second spot in the batting order. Detroit's Bobby Higginson, who had three homers and seven RBIs on June 30, 2007, against the Mets, was the first.
Washington outfielder Laynce Nix suffered a minor injury to his left foot during his final plate appearance on Monday night, and was not in the starting lineup on Tuesday. He will likely return to the lineup on Wednesday.
Following Wednesday's game, the Nationals return home for a six-game homestand against San Diego and Philadelphia. Washington is 11-9 at home. Tuesday's victory over the Nationals was Milwaukee's fifth straight win overall, and eighth straight win at home.
