This is just massive. Cahill was saying right before the draw that for Roger (because of his age), the scheduling would be more important than the draw itself. Then he specifically mentioned the staggered men's semis, saying that if Roger reached that stage and played the second semifinal, it would be "a significant hindrance because he's 37. Recovery is so much less than at 25." That's paraphrasing, but very close to his words.
