Eaton had not earned a decision after his first six starts, becoming the first pitcher in Phillies history to go six starts into a season without a decision. But he ended that run the wrong way after he allowed five hits, six runs and three walks in four innings of last night's 6-4 loss to the Arizona Diamondbacks at Chase Field.

The loss dropped the Phillies into a first-place tie with the Florida Marlins in the National League East.

Is there reason to worry about Eaton?

"Concerned? Yes. Worried? No," manager Charlie Manuel said.

Eaton opened the season with three quality starts and a 4.12 ERA (nine earned runs in 192/3 innings). But in his four starts since, he has had just one quality start and a 7.23 ERA (15 earned runs in 182/3 innings).

He lasted four or fewer innings in two of those starts.

Eaton allowed a run on three hits in the first inning to give the Diamondbacks a 1-0 lead. But after the Phillies took a 2-1 lead in the third when Eric Bruntlett hit a two-run homer to left field, Eaton allowed five runs in the fourth to make it 6-2.

It wasn't pretty, either.

"He needs a chance to stay out there sometimes," Manuel said. "He's got to do a job there. He had all the chances in the world to get out of the inning. He just didn't get it done."

Eaton walked Justin Upton to lead off the inning. Mark Reynolds doubled to right when the ball hit the heel of Jayson Werth's glove and fell to the ground, putting runners on second and third.

"I think that's what got the whole inning going," Werth said. "I take responsibility for that."

Eaton then walked Miguel Montero to load the bases.

The righthander picked up his first out but then committed a mortal sin when he walked Randy Johnson, who has the strike zone of a giraffe, on four pitches to score Upton, making it 2-2.

"I screwed up," Eaton said. "You walk the pitcher on the next four pitches, it's pretty pathetic."

"He didn't come close," Manuel said. "He was down or very high."

Another run came home on a fielder's choice before Stephen Drew hit a three-run homer to right, giving the Diamondbacks a four-run lead.

The Phillies scored a run in the fifth when Bruntlett doubled to score Shane Victorino and another in the sixth when Werth homered to center, but they couldn't get any closer.
