Frances Tiafoe advanced to his third US Open semifinal after beating fellow American Alex Michelsen 5-7, 6-3, 7-5, 6-3, 7-6 (10-6) in a five-set comeback on Tuesday. The win extended Tiafoe's strong record in high-pressure situations at the tournament, drawing comparisons to a similar comeback last accomplished by Roger Federer. The victory keeps Tiafoe's bid for a first Grand Slam title alive as the men's draw progresses toward the final stages. His performance added to a tournament already marked by dramatic upsets and deep runs from top American players.
