Early in his career, Lendl played a sliced backhand, but in the early 1980s he learned to hit his backhand with significant topspin. This shift allowed him to defeat John McEnroe in 1984 in the French Open, Lendl's first Grand Slam victory. In the first two sets, McEnroe used his habitual proximity to the net to intercept Lendl's cross-court passing shots. In the third set, Lendl started using lobs, forcing McEnroe to distance himself from the net to prepare for the lobs. McEnroe's further distance from the net opened the angles for Lendl's cross-court passing shots, which ultimately gained Lendl points and turned the match around.
