Lucas Pouille upset No. 4 seed Rafael Nadal in Sunday's U.S. Open fourth round, sending the Spaniard home by beating him 6-1, 2-6, 6-4, 3-6, 7-6(6) in just over four hours at Arthur Ashe Stadium.
Nadal, the tournament's No. 4 seed, hadn't dropped a set in three matches entering Sunday's fourth-round affair with Pouille. But he was shaky to start Sunday's match as the No. 24–seeded Pouille rolled the two-time U.S. Open champion in the opening set.
Pouille was never rattled, even after Nadal mounted two comebacks. After Nadal won the fourth set 6-3, the two players battled for more than an hour in a back-and-forth fifth set, which ended in a tiebreaker.
