The Williams sisters are headed home from the U.S. Open after their straight-set loss to No. 4 seeds Maria Kirilenko and Nadia Petrova on Monday night.
Serena is still alive in the singles tournament after throwing a double bagel on Andrea Hlavackova earlier in the day to advance to the quarters, but her night wasn't nearly as kind as her afternoon.
She and her sister dropped their first set to Kirilenko and Petrova in an abrupt 22 minutes. The Russian duo broke the Americans twice, hit eight winners and committed just one unforced error on their way to an easy 6-1 first-set victory.
From there, the Williams sisters were in a hole they just couldn't get themselves out of. They played significantly better in the second set, but failed to take advantage of three break points, as the Russians rolled to a 6-4 set win and a spot in the quarters.
The Williamses, although unranked because of their lack of activity in doubles tournaments, were seeking their 14th Grand Slam doubles title, but it appeared they just didn't have enough in the tank.
On the other hand, this was a huge win for the Russians, as neither woman is still alive in the singles tournament.
Kirilenko actually fell to Hlavackova in a match that could have set up a second matchup with Serena on Monday, while Petrova just missed a monumental upset on Sunday night against Maria Sharapova after a rain delay killed her rhythm.
The duo, which made it to the semis at Flushing Meadows last year, will take on the eighth-seeded Spanish team, Nuria Llagostera Vives and Maria Jose Martinez Sanchez, for a chance to get back there.
