3 questions:

1) When you win a series early and a starting pitcher becomes rusty for the next series, does being "rusty" hurt a pitcher's effectiveness?

2) Is it better to have that pitcher throw to a batter in an early playoff game and then come back as a starter "rested" and "not rusty" later?

3) When guys are brought up from the farm during the playoffs, they show up as being rusty, instead of being ready. Is that right?

Thanks
