Madison Keys and Kaia Kanepi will meet Wednesday in the 2017 U.S. Open quarterfinals.
Keys battled past No. 4-seed Elina Svitolina in the Round 16, winning 7-6(2), 1-6, 6-4 to reach her first U.S. Open quarterfinal. Kanepi, a qualifier, beat No. 38-ranked Daria Kasatkina 6-4, 6-4, marking her sixth trip to a major quarterfinal, but first since Wimbledon 2013.
Kanepi, ranked No. 418, has only played five events this year after suffering with plantar fasciitis in both feet. Keys' previous best result at a Grand Slam came at the 2015 Australian Open, where she advanced to the semifinals.
