He won eight Grand Slam singles titles — those are the biggest tournaments in tennis — and he spent many weeks as the world’s top-ranked player. Grand Slams include Wimbledon, the US Open, the French Open (Roland Garros), and the Australian Open. He also won almost 100 tournaments in his career. But what makes him special is how he practiced: running, lifting weights, and planning practice drills to stay fit and focused. Lendl played long, patient rallies and used power and precision to win points.
