Jason Bay has been scratched from Tuesday's Grapefruit League game with a strained intercostal muscle in his left rib cage.

GM Sandy Alderson indicated a disabled list decision could wait until shortly before the Thursday 11 a.m. deadline.

"We will have a move or two that we don't make until the very end," Alderson said.

Lucas Duda could be on Opening Day roster in that scenario. Nick Evans would be an alternative. His waiver verdict is expected to come at 1 p.m. today.

Bay is due to head back to Port St. Lucie to be examined by doctors. Alderson did not believe Bay's injury was related to the back stiffness that idled him during the weekend. The GM added that he was not aware of the severity.

"He didn't want to speculate. I didn't ask him to speculate," Alderson said. "We'll just wait to see what the doctors think."
