i suspect this match to enter in the record memory with the number of aces.
From the atp website there is an interesting stats.
Number of aces in 2009 (wimbledon is not included):
1/ Karlovic: 485 for 27 matches
3/ Tsonga: 359 for 41 matches
1st serve won:
1/ Karlovic: 84%
3/ Tsonga: 78%
Service games won:
2/ Karlovic: 91%
3/ Tsonga: 88%
(i dont add the last one bp saved, there is more difference and not in good side
)but some stats from both are just
Tomorrow wil be a match of 2 aces machines
The one who will return more will win. They were talking about it in carrement tennis this morning and they said that Jo should not keep frustated to face lot of aces because on few points that Karlovic will have worst first serve it will be at this moment he could win the match, but it will not be easy.
