PHOENIX - Adam Eaton opened the season with three consecutive quality starts and a 4.12 ERA, but his last four haven't been as good, and that could be reason to worry, considering his track record with the Phillies.

Eaton has a 7.23 ERA in his last four starts.

"Concerned? Yes. Worried? No," manager Charlie Manuel said after Tuesday's 6-4 loss to the Diamondbacks.

Eaton allowed five hits, six runs and three walks in four innings Tuesday. Those three walks came in the fourth inning, in which the Diamondbacks scored five runs. That included walking pitcher Randy Johnson on four pitches with the bases loaded to force in the tying run.

"I [messed] up," Eaton said.

"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."

Harman to go

It is expected that infielder Brad Harman will be optioned to the minor leagues when Jimmy Rollins is activated from the disabled list, which could happen before tomorrow night's game against the San Francisco Giants at AT&T Park.

Harman, who opened the season in double-A Reading, has hit .125 (1 for 8) with one double and one RBI with the Phillies, but Manuel sees a bright future for him.

"I like Harman," he said. "He's going to be a good hitter. His bat is going to carry him back."

Gavin is good

Former Phillies phenom Gavin Floyd came within two outs of throwing a no-hitter Tuesday for the Chicago White Sox. The Phillies traded Floyd and Gio Gonzalez to the White Sox on Dec. 6, 2006, for Freddy Garcia.

"He looked like the guy that pitched that game in St. Louis for us," Manuel said.

Floyd allowed three hits and one run in seven innings while pitching for the Phillies against the St. Louis Cardinals on April 9, 2005. But Floyd struggled after that, and the Phillies finally traded him.

"I think the change of scenery helped him," Manuel said. "I think it definitely helped him. I think he was ready for a change of scenery from Philadelphia. That's been good for him."

Caught in the Webb

Phillies righthander Brett Myers (2-2, 4.70 ERA) faces Diamondbacks righthander Brandon Webb (7-0, 2.49 ERA) in the series finale this afternoon.

Opponents have hit just .197 against Webb. He's won nine consecutive starts dating to last season.

Extra bases

The Phillies entered the night with 50 homers in 34 games, the best mark in baseball. They didn't hit 50 homers until their 49th game last season, when they finished second in the National League with 213 home runs. . . . Phillies pinch-hitters were hitting .259 (15 for 58), the fourth-best mark in the league. They led the league in hits, home runs (three), slugging percentage (.466) and RBIs (11).
