Tim Henman spent just over an hour beating Marc Rosset in the first round of the Masters Series event in Monaco.
Henman made the ideal start, breaking the giant Rosset's usually formidable serve in the opening game and looking fully in control on his own.
Marc Rosset's victory four years later in Barcelona was an even greater shock in a field that included Pete Sampras, Boris Becker and Stefan Edberg.

And Rosset - who lives in Monaco - looked to be heading to another defeat when he let his serve slip again in the fifth game.
It left Rosset a frustrated figure, and the Swiss received a warning for swearing during the game before a penalty point was docked when he threw his racket down.
Henman overcame Swiss star Rosset 6-3, 6-2.
