Stanford grad Scott Lipsky and his doubles partner Rajeev Ram continued their run at the US Open in Flushing Meadows, advancing into the quarterfinals with a 6-3, 6-4 victory over third-seeded Daniel Nestor of Canada and Nenad Zimonjic of Serbia on Sunday.
Lipsky has now reached the quarterfinal round of all four Grand Slam events. His best previous finish at the US Open was in the third round of the 2012 tournament.
Lipksy's lone Grand Slam title was in mixed doubles, with Australia's Casey Dellacqua, at the French Open in 2011. They were unseeded, beating the defending champions, which included Zimonjic.
Lipsky and Ram play USA's Eric Butorac, a former Lipsky doubles partner, and Russia's Raven Klaasen. They beat Spain 's Guillermo Garcia-Lopez and Austria's Philipp Oswald, 4-6, 6-3, 6-4, in the third round.
Lipsky was a three-time All-American at Stanford and was part of its last NCAA title team in 2000. He was ranked second, with David Martin, in doubles. The pair turned pro together.
Ram won a team title with Illinois in 2003 and was also the NCAA doubles champion that year. Ram and Lipsky played together in San Jose, winning the 2011 SAP Open doubles title.
The top-seeded doubles team of Stanford products Bob Bryan and Mike Bryan are scheduled to meet Stanford grad Bradley Klahn and his partner, Tim Smyczek, Monday at 8 a.m. (PT) in the Louis Armstrong Stadium.
