Karlovic is very tall at 6'10' and his fastest serve has been recorded 153mph at this rate no matter who it is even roger federer cannot take him on.He doesnt play much of volleys because he gains points with his aces.nobody could not take his serve this year in wimbleon.On grass he can be impossible to play,.he was the only one from 1965 to beat a wimbledon champion on the opening day.but between 2005-2008 he did not win even a single match at all england cup.
