Frances Tiafoe, a 19-year-old from Hyattsville, Md., pushed Roger Federer, a 19-time Grand Slam champion, deep into a fifth set in the first round of the United States Open on Tuesday night under the roof of Arthur Ashe Stadium before losing, 4-6, 6-2, 6-1, 1-6, 6-4.
“How many years have I been watching the U.S. Open? Since I was a little kid,” Tiafoe said after the match. “I always dreamed of being on center court, playing the best in the world. Finally happened, so I was ready for it.”
