Ivo Karlovic creates the Ace Record in tennis

Ivo Karlovic hit 78 aces, destroying his own previous record of 55 to make a new record for number of aces in a match. Well done to him - an impressive achievement to not just break the record but blow it apart.

Of course one of the most interesting things about this is that he still lost the match (16-4 to Stepanek in the 5th with the 4 first sets on tiebreaks)! As he did when he hit 55! So hmm what does this tell us about the rest of his game?
