Worth noting

• Reliever Kevin Gregg is scheduled to undergo season-ending surgery to remove bone chips from his right elbow on Thursday. The veteran reliever has been on the DL with right elbow inflammation since July 18, retroactive to July 14.

Enrique Hernandez made his first start for the Marlins on Wednesday night. While Jordany Valdespin has been receiving most of the playing time at second base, he hasn't played much against lefties. Hernandez, acquired from the Astros on July 31, is a right-handed-hitting infielder. Redmond is in the process of trying to ease Hernandez into action.
