Chad Billingsley (groin) did not throw his scheduled bullpen session on Thursday, but will throw in a simulated game on Sunday instead of making his scheduled start.
Torre said that was more because pitching coach Rick Honeycutt wanted to monitor the bullpen session, and Honeycutt was in Tucson for the game against the Rockies, than a new setback with his injury. Billingsley is now supposed to throw a bullpen session today.
LHP Eric Stults will start on Sunday, followed by promising youngster Josh Lindblom.
Claudio Vargas, who was roughed up for four runs in one inning on Wednesday, experienced elbow discomfort on Thursday, but Torre said it was due to a change in the way he was gripping his slider, than related to his past elbow injury.
