After a bad-as-can-be start, dropping the first three games, Serena Williams quickly turned things around and stretched her U.S. Open winning streak to 19 matches to get back to the semifinals.
Tenth seed Kei Nishikori became the first Japanese player in the Open Era to advance to a Grand Slam semifinal with a five-set win over 2014 Australian Open champion Stan Wawrinka 3-6, 7-5, 7-6, 6-7, 6-4.
The match went 4 hours, 15 minutes, and the 10th-seeded Nishikori managed to shake off any lingering exhaustion from his previous victory, which lasted 4:19 and ended at 2:26 a.m. Tuesday, equaling the latest finish in tournament history.
