1. Lleyton Hewitt
The 32 year-old Australian has been in the tennis wilderness for a while now, with many expecting him to bow out with a whimper, Lleyton has other ideas. A former winner of Wimbledon way back in 2002, Hewitt did reach the semi-finals of Queens, defeating Del Potro in the process, with his ever impressive defensive play shining through. After an incredibly gutsy performance against 11th seed Stanislas Wawrinka in the 1st round today, defeating him in straight sets, Hewitt certainly has proven he is in top form and judging by his reaction when winning, extremely motivated aswell. Lleyton would have expected to have met Rafael Nadal in the 4th round, but after Nadals defeat earlier this after, Hewitt can hope to build on his victory today with a series of strong performances that will hopefully lead him to the 2nd week of the tournament. Watch out for Lleyton.
