Tomorrow is an off-day, so probably not as critical for them to do that. I'd imagine we could see some position players for the final two innings though (or is that allowed in the postseason?)
The Jays could sweep them and all they'll talk about is how the Yankees were the better team and got unlucky. Ignore it. They're telling their audience what they want to hear. This was a statement game and it's now up to the Yankees to respond to it on the field.
Yesavage can probably negate the short porch better than the other guys too just based on how his ball moves. That's a hell of an environment to throw him into though.
