Phillies pitcher Roy Halladay denounced critical comments about Phillies pitching coach Rich Dubee made by former Phillies reliever and current MLB Network analyst Mitch Williams.

In a Friday radio interview on WIP-FM (94.1), Williams said the Phillies need a new pitching coach.

"It is not personal," Williams said. "I think these pitchers have to hear something new."

The Phillies have struggled not only in pitching but all facets of the game. They entered Friday 26th in the major leagues with a 4.42 ERA.

Halladay, one of the pitchers that Williams suggested hasn't been helped by Dubee, talked to reporters before Friday's game at Citizens Bank Park against the Miami Marlins.

"There are very few pitching coaches that I respect more than Rich Dubee, and watching Kyle Kendrick, the stuff that he's learned, the way that he's grown, it's because of Rich Dubee, and it's because of his work ethic and the way he goes about things," Halladay said. "It really does upset me."

Williams also told WIP's Angelo Cataldi that Dubee told Williams in spring training that he didn't like the fact that Williams was talking to the Phillies pitchers.

"I got yelled out in front of people and was really irritated," Williams said.

When asked about the biggest change in Kendrick, now 3-1 with a 2.43 ERA, Williams replied: "He added a change-up. I can't say anything because I showed him a split, and I am not supposed to talk to their pitchers."

Dubee, now in his ninth season as Phillies pitching coach, briefly responded.

"Maybe [Williams] got upset because I spoke to him about getting involved about our pitching where I don't think he belongs," Dubee said. "Maybe he's upset at that. But I don't think other people belong in our pitching."

Williams mentioned that Dubee wasn't effective working with Halladay.

"When Halladay was struggling earlier, it was plain as day what was wrong, and it wasn't fixed," Williams said. "You watch things go on, and it may be time for a new voice to the pitchers."

Halladay took exception.

"I just feel he's wrong on this one," Halladay said. "And I'm sure he's not a bad guy. I'm sure he's trying to do the best he can at his job, but I really feel like he was kind of off the mark on this one."

Williams could not be reached for comment.

Revere back in lineup

Ben Revere started in center after Thursday's game with a jammed right ring finger. Revere suffered the injury during Wednesday's 6-0 loss at Cleveland. X-rays were negative, but he had to wait until the swelling subsided.

"Most of the swelling is gone and I told Charlie [Manuel] that I could go," Revere said before the game.

Hail Cesar, Biddle

Reading lefthander Jesse Biddle and Lehigh Valley second baseman Cesar Hernandez were named the Phillies minor-league pitcher and player of the month.

Hernandez batted .375 with a .917 on-base-plus-slugging percentage and was successful on all seven stolen-base attempts in April.

Biddle, the 2010 first-round draft choice from Germantown Friends, was 2-1 with a 1.74 ERA in five April starts. He struck out 40 in 31 innings, including 16 in one game.

"Cesar had a consistent month in April while playing in tough conditions, and he really did everything for us," said Joe Jordan, the Phillies director of player development. "Jesse really has shown a lot of growth as a pitcher, and his stuff is better and so is his ability to use it."
