THE ALL ENGLAND CLUB, LONDON — Thursday night, Ben Shelton remonstrated with officials as darkness fell over Wimbledon, after the tournament suspended his second-round match just as he was about to serve for the win. Friday afternoon, Shelton took one minute, 10 seconds, three aces and one unreturned serve to complete a 6-2, 7-5, 6-4 win.

Shelton lost the first set 6-3 against Italian Lorenzo Sonego, who is ranked No. 47 in the world, before taking the next three sets to advance to the first Wimbledon quarterfinal of his career. With victory, Shelton became the youngest American to go this far in the tournament since Andy Roddick in 2004.
