Upsets, Oh My!

Novak Djokovic and Marion Bartoli were two of the hottest player through Wimbledon, but they seem to have cooled off a bit in the summer heat.

Djokovic fell to unheralded countryman Viktor Troiki in the second round of the Croatian Open. The tournament lost its top three seeds in the first two rounds alone.

Meanwhile, Bartoli lost to American Lilia Osterloh at Stanford after suffering a strained leg muscle in the first set.

And you thought these youngsters were invincible.....
