I actually do favour Karlovic over Jo Wilfred Tsonga here as the big hitting Croatian has got certainly one of the strongest serve on tour and his record on grass is just unbelievably good. He even managed to served an all time high of 63 aces in Roland Garros which was a much slower surface and you would not expect Karlovic to lose much service games especially with his non-returnable serves. Karlovic is thirty six in the world right now and Tsonga is ninth but I do not expect Tsonga to play taht well because grass is his worst surface and I do think that his struggles will continue. He was even booted out of Halle open by an average Tommy Haas 2 weeks ago.

Karlovic went out agonisingly close to Roddick in the semi finals at Queens but overall his record against the top 10 players on tour has been very good even though some were losses. Go for the Croatian to enter the round of sixteen at this year's Wimbledon.

Pick: Ivo Karlovic @2.62
