UNIONDALE, N.Y. -- John Isner advanced to the semifinals of the New York Open, where he will face the player who knocked him out of the Australian Open.
Opelka upset the ninth-ranked Isner in four sets — all in tiebreakers — in Melbourne. The match between the 6-foot-10 Isner and the 6-11 Opelka was the tallest matchup in Grand Slam history.
The other semifinal will be No. 6 Sam Querrey, a finalist last year in the tournament's debut on Long Island, against Canadian Brayden Schnur. Querrey beat Jason Jung of Taiwan, 6-3, 3-6, 6-3, and Schnur outlasted Paolo Lorenzi of Italy, 6-7 (7), 7-6 (5), 7-5.
