David vs Goliath

This image of the trophy presentation at the just concluded Barclays ATP Tour World Finals in London show Juan Martin del Potro of Argentina, at 6'6" towering over the slightly built Nikolay Davydenko of Russia. Davydenko's height is listed as 5'10". The discrepancy didn't matter though - the smaller player beat the bigger one proving once again that it's performance, and not size that really matters.
