Pettitte, 40, is 2-0 with a 1.20 ERA. Pettitte had his previous start skipped after suffering back spasms. Pettitte favored taking the mound either on Tuesday or Wednesday, but now will have had 10 days since his last start.
"It was a good decision," Pettitte said. "I don't want to second-guess anybody."
Pettitte said the one thing he will have to be careful about with the long delay between starts is feeling too strong on Friday.
NUNEZ BACK AT SHORT: After being hit on his right wrist on Friday, Eduardo Nunez returned to the starting lineup on Tuesday. Nunez said the wrist is better. So far this season, the same could be said about Nunez' defense. He has yet to make an error.
"I feel comfortable the more games they give to me, the more confident I feel," Nunez said.
Nunez said it was helpful that he is only playing one position. During 2012, the Yankees sent Nunez down after he could not handle the utility role.
HONORING JACKIE: The Yankees and the Diamondbacks are all wearing No. 42 on Tuesday night to honor Jackie Robinson.
JETER LIGHTENS WORKLOAD:I have a news story on Derek Jeter lightening his workload. The idea that he might return in early May seems remote.
SWEET CAROLINE: I also have a news story on the Yankees honoring Boston by playing Sweet Caroline Tuesday night. In the story, Kevin Youkilis has some poignant comments about how the tragedy impacted him.
