Frances Tiafoe rolls over Andrey Rublev to reach US Open semi-finals

• Tiafoe wins 7-6 (3), 7-6 (0), 6-4 to reach US Open semi-finals
• No 22 seed is first American to reach men's semis in 16 years

Andrey Rublev and Frances Tiafoe first stared each other down as rivals on the courts of Flushing Meadows in 2014. They were both 15 years old then, Tiafoe born three months later in January 1998, and as two of the most hyped youngsters of their time they knew each other well. They battled to the death in a fierce contest in the quarterfinals of the US Open juniors, with Tiafoe toppling the top seed in a tight three-setter. Afterwards, they saluted each other in a warm embrace.

While Rublev rose swiftly towards the top of the game as they transitioned to the professional tour, Tiafoe's path has been far less clear. His progress has at times been arrested by inconsistency, lapses of concentration and far too many tight, brutal losses after great performances. But finally, on the biggest court of those same grounds, Tiafoe made his move to the top of the sport in his own time.
