A quick look at the U.S. Open :
LOOKAHEAD TO TUESDAY
When 6-foot-6 (1.98-meter) Sam Querrey takes on 6-8 (2.03-meter) Kevin Anderson in the U.S. Open quarterfinals in Arthur Ashe Stadium on Tuesday night, it will be the tallest combined matchup in a quarter, semifinal or final at any Grand Slam tournament in the Open era, which dates to 1968. That's according to the ATP. Both men are tall, both have intimidating serves and both are attempting to get to the final four at Flushing Meadows for the first time. Querrey, a 29-year-old American seeded 17th, made his major semifinal debut in July at Wimbledon. Anderson, a 31-year-old South African seeded 28th, lost his only previous quarterfinal at a major tournament two years ago in New York. This is their 15th career matchup, with Querrey holding an 8-6 edge. The winner this time will face No. 12 Pablo Carreno Busta of Spain or No. 29 Diego Schwartzman of Argentina, who meet in the afternoon. One member of this quartet will be a Grand Slam finalist for the first time. The women's quarterfinals are No. 9 Venus Williams vs. No. 13 Petra Kvitova of the Czech Republic, and No. 16 Anastasija Sevastova of Latvia vs. Sloane Stephens. Williams owns seven Grand Slam titles, including two at the U.S. Open in 2000 and 2001, while Kvitova won Wimbledon twice. Theirs should be a showdown filled with powerful strokes from both. Sevastova, who eliminated Maria Sharapova in the fourth round, tries to get to her first major semifinal, while Stephens - who missed the first half of the year after foot surgery in January - made it that far at the 2013 Australian Open.
