Frances Tiafoe offers hope for present and future of US men's tennis

Frances Tiafoe's run to the U.S. Open semifinals is, first and foremost, about Tiafoe himself, a 24-year-old from Maryland who took up tennis because his father was a janitor at a junior training center, a player who never won a match past the fourth round at a Grand Slam tournament until now, who owns one career ATP title and a sub-.500 career record, and whose ranking ranged from 24 to 74 over the past two seasons.
