Answer
Roger Federer, the eight-time Wimbledon champion, was defeated by Kevin Anderson in the 2018 Wimbledon quarterfinals. Anderson, a South African player, won the match in straight sets, 7-6(4), 6-7(5), 7-5, 6-4. This was a major upset, as Federer was the top seed and had not lost a set in the tournament up to that point. Anderson's victory marked the first time that Federer had lost a Wimbledon quarterfinal since 2008.
