From Jon Weisman of Dodger Thoughts:

Randy Wolf, who has emerged as a stalwart of the Dodger rotation, had been scheduled to pitch Friday against San Francisco but now will miss that start with an irritated elbow, according to a note I just received from Dodger beat writer Dylan Hernandez of The Times. Hiroki Kuroda will make that start on four days' rest, followed by Vicente Padilla on Saturday and Chad Billingsley on Sunday.

Bad news for the Dodgers, as Wolf has really been the most dependable starting pitcher on the staff.  Clayton Kershaw was originally scheduled to start Friday, but was scratched on Monday because of a Sunday collision with the outfield wall during batting practice.  Now Wolf is out.  If I were Hiroki Kuroda, I'd be looking over my shoulder.

That Jon Garland acquisition is looking better and better by the minute.
