Stefan Edberg, ranked No. 1 in the world suffered a shocking defeat against fellow Swede Magnus Larsson Wednesday night in his opening match at the Monte Carlo Open.

Top seed Edberg won the first set after a hard battle, but Larsson rallied for a 5-7, 6-3, 7-6 victory.Fourth-seeded American Andre Agassi was also a second-round victim, losing 6-0, 6-7 (3-7), 6-3, to Austrian Horst Skoff. No. 2 seed Boris Becker advanced with a hard-fought 6-7 (3-7), 6-3, 6-3 triumph over Spaniard Javier Sanchez.

Larsson served much better than his opponent, while Edberg made numerous unforced errors and lost his serve in the fifth game of the deciding set.

Unlike Edberg, Agassi got off to a bad start and could not fully recover.

After falling behind 2-0 in the first set, Sanchez won five points in a row and drew even with Becker, forcing the tie-breaker, which he won with a backhand volley that was reminiscent of Becker himself.

Becker broke in the seventh game of the second set to go ahead 4-3 and held for 5-3 when Sanchez asked the Australian referee to stop the match because of rain.

Ings agreed and play stopped for about an hour.

When they resumed, Becker looked confident. He immediately broke Sanchez' serve to clinch the second set and even the match. The players traded breaks in the sixth and seventh games of the final set before Becker broke again for 5-3 and served out the match.
