Delpo

Men’s tennis so-called 'Big Four' have dominated Grand Slam play over the last two years, but they may be about to be rejoined by a man who could make it a fearsome Big Five, Juan Martin Del Potro, the 2009 US Open champion.

On Sunday at the Australian Open, the towering Argentine took a clinical 6-4, 6-1, 6-1 victory over the talented German, Philipp Kohlschreiber. The calm Del Potro stuck with his plan of playing deep, consistent and sometimes lethal tennis, knocking off 31 winners and committing only 12 unforced errors. He served only six aces in the match, but has served 40 aces in the tournament, more than anyone else left in the draw.
