No call from the line judges or Layhani but I'm surprised Kohlschreiber did not challenge it.
Anyways, Federer is through and will now face Tommy Haas in the 3rd round on Thursday. Great first set from Federer but a horrible 2nd set. I think he had 20 unforced errors in the second set. He needs to clean up a little bit to advance deep in the tournament.
Oops! I apologized, Haas still hasn't completed his 2nd round match. He will face Granollers tomorrow and the winner of the match will face Federer on Thursday.
