New Philadelphia GM Ruben Amaro Jr. was upbeat after second baseman Chase Utley had surgery on his right hip Monday.

"What I can tell you is that our early reports are that it was a very successful surgery," Amaro said.

Utley's recovery time has been estimated between four and six months.

"Whenever you have surgery, I don't know it's good news, but favorable, I think, would be a better word," Amaro added.
