Four who rose to greatness on grass
Bjorn Borg - won 11 grand slam titles and famous for winning Wimbledon five times in a row between 1976 and 1980. He confounded the accepted wisdom that consistently to win titles on fast surfaces in the men's game you had to come to the net. However, Borg won more French Open titles - six - although he had a mental block about the US Open which he never won, and only ever once made the trip to contest the Australian Open. Retired at 26.
John McEnroe - won only seven grand slam titles although his influence on the game has been immense. During three Wimbledon triumphs he became renowned for an unorthodox serve with which he would appear to deliver the ball round corners, for quicksilver volleying, and for a volcanic intensity. But after taking six months out of the game he never got back to the top.
Boris Becker - won six grand slams events but his hugely intimidating game did not translate well to clay and he never won the French Open. His three Wimbledon successes helped usher in the modern power game. With the arrival of graphite rackets he showed it was possible to go for broke with almost every shot.
Pete Sampras - a record 13 grand slam titles, but his claim to being the all-time great is marred by his inability to win on clay. During his seven Wimbledon wins he developed an almost perfect grass court game. It was based around a serve which combined speed with great accuracy and consistency, and was supported by tremendous movement and smothering volleys.
