of Croatia will be aiming to make a great run in the 2011 season and hopefully from his point of view beat some of the best players in the world.
The Croat made a name for himself back in 2003 when he beat the then world number 1 and defending Wimbledon champion Lleyton Hewitt of Australia in the 1st round in 4 sets.
Karlovic also beat the then world number 1 Roger Federer of Switzerland in the quarter finals of the ATP Masters 1000 event in Cincinnati Ohio back in 2008.
Federer this year won in Ohio for the 4th time in his career when he beat Mardy Fish of the USA in 3 tight sets.
The Swiss maestro however was then beaten in 5 sets by the world number 2 Novak Djokovic of Serbia 5-7 6-1 5-7 6-2 7-5.
Djokovic however lost in the final in 4 sets to Rafael Nadal.
