Sampras, with seven Wimbledon trophies in his possession, endured one of the worst defeats of his career, losing 6-3 6-2 4-6 3-6 6-4 in the second round to a player ranked 145th in the world and who was a lucky loser from qualifying.
American Sampras recovered to win the U.S. Open a few weeks later before retiring.

A 32-year-old Agassi, seeded three after a stunning career revival, joined old rival Sampras on the scrap heap after being dismantled by Thailand's Srichaphan 6-4 7-6 6-2.
The second round match was all over in one hour 47 minutes.
1987 - Australian Peter Doohan beats Boris Becker.
Becker, the top seed and twice defending champion, seemed invincible on the Wimbledon grass but ran into 70th-ranked Doohan in the second round.

1985 - Kevin Curren beats John McEnroe
Defending champion McEnroe had compiled an 82-3 record the previous year and was still the "Guvnor" at Wimbledon, reaching the previous five finals.
However, South African Curran proved no shrinking violet and won the last eight clash 6-2 6-2 6-4. McEnroe was never quite the same again, failing to win another grand slam. (Compiled by Toby Davis; editing by Ken Ferris)
