The Yankees' path to the postseason got more challenging after last night's rainout against the Blue Jays.

Not only was Andy Pettitte pushed back a day, likely limiting him to three starts for the rest of the regular season, they will also be forced to take David Phelps out of the bullpen and insert him back into the rotation — at least for one game.

Pettitte had become used to waiting since fracturing his left ankle on June 27, but admitted this wasn't ideal.

"Now it'll be a week since I've thrown the simulated game," Pettitte said of today's start against Toronto and Henderson Alvarez in the first game of a day-night doubleheader in The Bronx.
