One of the greatest Grand Slam winning streaks in men’s tennis came to an end in upset fashion on Monday night.
Seeking his fifth US Open singles title, two-seeded Rafael Nadal was upset by 22-seeded Frances Tiafoe in four sets (6-4, 4-6, 6-4, 6-3) to advance to the quarterfinals. Nadal had previously reached at least the quarterfinal round in each of the last 16 majors he participated in, and he had won the prior 22 Grand Slam matches.
