Frances Tiafoe becomes first American man to reach U.S. Open semifinals since 2006

American Frances Tiafoe's remarkable run in the U.S. Open continued on Wednesday night. 

Two days removed from an upset over Spain's Rafael Nadal, Tiafoe defeated Russia's Andrey Rublev, 6-7, 6-7, 4-6, to advance to his first career Grand Slam semifinal. 

Wednesday's feat wasn't just a career mark for Tiafoe, but it also snapped a nearly two-decade streak of bad luck for American men at the U.S. Open. Tiafoe became the first American man to advance to the U.S. Open semifinals since Andy Roddick did it in 2006, breaking a 16-year drought.
