Frances Tiafoe and Taylor Fritz have made history by setting up an all-American semifinal at the US Open, marking the first time since 2005 that two American men will feature in the semifinals at Flushing Meadows. Tiafoe defeated Grigor Dimitrov, who retired due to a hamstring injury, while Fritz overcame Alexander Zverev in a tightly contested match. Their victories ensure that an American man will compete in a Grand Slam final for the first time since Andy Roddick in 2009. On the women's side, Emma Navarro reached her first Grand Slam semifinal by defeating Paula Badosa, following her upset of defending champion Coco Gauff. This tournament has reignited hopes of ending the long wait for an American male Grand Slam champion, last achieved by Roddick in 2003.
