Venus and Serena Williams continued their doubles dominance on Day 7 of the US Open with a convincing 6-1, 6-0 rout – technically an upset – over the No. 12 seeds, Garbine Muguruza and Carla Suarez Navarro of Spain. Continuing their quest for a 14th Grand Slam doubles title, the Williams sisters made just four unforced errors in the 47-minute match, winning 95-percent of their first serve points.
Along with Venus and Serena, two other all-American teams achieved big upsets on Sunday. First, Taylor Townsend and Donald Young claimed a spot in the mixed doubles quarterfinals after defeating the No. 2 seeds, Andrea Hlavackova of the Czech Republic and Alexander Peya of Austria, 6-3, 6-3.
In men's doubles, Scott Lipsky and Rajeev Ram earned a straight-sets upset of their own. The unseeded Americans beat the No. 3 seeds, Daniel Nestor of Canada and Nenad Zimonjic of Serbia, 6-3, 6-4.
Another all-American pair on court today, Vania King and Lisa Raymond, almost caused another upset against Russians Elena Makarova and Elena Vesina. The No. 4 seeds ultimately prevailed, however, winning in three sets, 6-3, 6-7, 6-2.
No. 4 mens’ doubles seeds Ivan Dodig of Croatia and Marcelo Melo of Brazil cruised to a 6-4, 6-4 win over Mariusz Frystenberg and Marcin Matkowski of Poland, while No. 12 seeds Eric Butorac of America and Raven Klaasen of South Africa needed three sets to defeat Guillermo Garcia-Lopez and Philipp Oswald of Austria, 4-6, 6-3, 6-4.
After a brief rain delay, the No. 6 mixed doubles seeds Anabel Medina Garrigues of Spain and Raven Klaasen of South Africa topped Katarina Srebotnik of Slovenia and Rohan Bopanna of India, 6-3, 6-4.
On Court 11, Americans Christina McHale and Stefan Kozlov fell 5-7, 6-2, [10-8] after dropping a third set super tiebreaker to Kveta Peschke of the Czech Republic and Marcin Matkowski of Poland.
Day 8 of the Open features the No. 1 men’s seeds and four-time US Open doubles champions, Bob and Mike Bryan. The Bryan brothers are set for an all-American clash against Bradley Klahn and Tim Smyczek in Louis Armstrong stadium tomorrow morning.
