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.
