I just checked, and as far as I can tell, Ian Kennedy could be called back up to start Wednesday at Tampa Bay instead of Kei Igawa.
Before tonight's game, manager Joe Girardi said "there's no situation we've talked (about) as of right now" that would keep the Yankees from starting Igawa again Wednesday at Tampa Bay.
But that was before tonight's awful performance.
Baseball rules require an optioned player, such as Kennedy, to spend 10 days in the minors before returning (unless he replaces a player put on the disabled list). Kennedy was optioned last Sunday, so the 10th day is Tuesday. From what I am told, the 10-day count begins the day of the assignment, not the day the player physically reports to the minor-league team (last Monday, in Kennedy's case).
The bottom line: If the Yankees don't want to give Igawa another turn, they can use Kennedy on Wednesday. It would take some sort of creative scheduling, since Kennedy pitched Tuesday and is scheduled to go again Sunday.
