Moyer hopes to find elixir against Reds

Philadelphia (21-16) at Cincinnati (20-18), 7:10 p.m. ET

CINCINNATI -- The Phillies bumped Chan Ho Park from the rotation to the bullpen Tuesday, but he actually didn't have the worst ERA in the rotation.

Jamie Moyer did.

Moyer pitches Wednesday night against the Reds at Great American Ball Park at 3-3 with an 8.15 ERA in seven starts. That would be the worst ERA in baseball if Moyer had enough innings to qualify for the rankings. But while Park's move to the bullpen made sense, the Phils aren't going to do anything Moyer -- except let him pitch. After all, he won a team-high 30 games for Philadelphia the last two seasons.

"If he's hitting his spots, if he's putting the ball where he wants it, he'll be good," manager Charlie Manuel said. "When he tells me that, I trust that. That's what he's been pitching off of ever since he's been here. It's his command and where he puts the ball and everything."

Phillies pitching coach Rich Dubee said he has been working with Moyer on what he characterized as minor mechanical adjustments to improve his location.

"Jamie is always making adjustments," Dubee said. "We've been working on his delivery. Subtle adjustments that a lot of people wouldn't see."

They hope they see some improvements beginning Wednesday. It will be Moyer's first start in Cincinnati since May 4, 1991, when he pitched for the Cardinals. Phils hitting coach Milt Thompson started for the Cards that day and went 2-for-3 with a walk and a run scored.

Moyer went 16 years, 44 days in between starts against the Reds (May 14, 1991-June 27, 2007), which was the third-longest gap in Major League history for a pitcher in between starts against one team.

Pitching matchup
PHI: LHP Jamie Moyer (3-3, 8.15 ERA)
Moyer has been struggling lately. He allowed eight hits and seven runs in 4 1/3 innings last Wednesday against the Dodgers. It was his second consecutive start in which he has allowed seven runs. Moyer is 0-2 with a 13.86 ERA (19 earned runs in 12 1/3 innings) in his past three starts. It is his worst three-start stretch since he went 0-1 with a 16.62 ERA (16 earned runs in 8 2/3 innings) from April 30 to May 11, 2005, when he pitched for the Mariners.

CIN: RHP Aaron Harang (3-4, 3.44 ERA)
Harang's overall numbers are good: 55 hits and 12 walks in 52 1/3 innings to go along with the 3.44 ERA. Last time out, though, he gave up five runs on eight hits and two walks in 6 1/3 innings in a loss to the Padres.

Left-hander J.C. Romero will make a rehab appearance Wednesday with Double-A Reading. ... The Phils expect infielder Miguel Cairo, who had been designated for assignment Friday, to join Triple-A Lehigh Valley on Thursday. ... Entering Tuesday, the Phillies led all Major League teams in hits (49) since May 15. They ranked second in batting average (.327) and runs scored (33), third in slugging (.520) and extra-base hits (16) and sixth in walks (22).
