I didn't watch the match but have just caught up with the score. I too wondered if Haas could maintain the level of play he had against Djoko, but his confidence must be soaring now, so his match against Ferrer should be very interesting.
It was a great match. Long rallies, and great net play. I think Tommy won 15/18 net points.
I'd love to see a Haas/Murray final (with Andy winning, of course!) but I'm loving watching Tommy finding the sunshine in his autumn years.
