Venus Williams reached the U.S. Open quarterfinals for the second time in three years with a 6-3, 3-6, 6-1 victory over Carla Suarez Navarro of Spain.

- Pablo Carreno-Busta (Spa) bt Denis Shapovalov (Can) 7-6 (7-2) 7-6 (7-4) 7-6 (7-3)
The spotlight has never been on Pablo Carreno Busta as it has been here at the US Open but the 26-year-old Spaniard came through his latest test in emphatic style. The highest ranked player left in the bottom half of the draw barely put a foot wrong in beating Denis Shapovalov 7-6, 7-6, 7-6 in Arthur Ashe Stadium on Sunday to secure his place in the quarter-finals.
Being a tennis player in the era of Rafael Nadal – not to mention David Ferrer, Feliciano Lopez, Fernando Verdasco and a host of other successful Spaniards – has meant that Carreno Busta has flown under the radar for most of his career, but the world No 19 has won three titles in the last 12 months and has also started to make his mark at Grand Slam level.

The 25 year old was efficient on return as well, converting an impressive seven of nine break chances. At 5’7″, Schwartzman is the shortest Grand Slam quarter-finalist since fellow 5’7″ South American Jaime at the 1994 US Open.
