The towering Kevin Anderson took advantage of an even bigger opportunity, beating 17th-seeded Sam Querrey, 7-6(5), 6-7(9), 6-3, 7-6(7), in a quarterfinal match that began Tuesday night at the United States Open and ended at 1:51 a.m.
Twenty-eighth-seeded Anderson will face 12th-seeded Pablo Carreño Busta in the semifinals on Friday. Carreño Busta, who beat 29th-seeded Diego Schwartzman, 6-4, 6-4, 6-2, in Tuesday’s first quarterfinal, has also reached the semifinals of a major for the first time. It’s a rare window of opportunity in an era of tennis dominated by the so-called Big Four: Novak Djokovic, Roger Federer, Rafael Nadal and Andy Murray.
