Swiss tennis star Michel Kratochvil has failed to build on his successful performance at last week's Open Tennis Tournament in Gstaad after crashing out of the ATP tournament in Amsterdam in the first round.

Kratochvil, who won through to the quarter-finals in Gstaad, was knocked out of the $400,000 Dutch tournament by the Russian Alexeï Stoliarov in straight sets, 4-6, 3-6.

The Swiss number two seed and Davis Cup player has now suffered his eighth first-round defeat of the year.

Despite his unexpectedly early departure from the tournament in Amsterdam, Kratochvil still had something to smile about on Monday.

The 22-year-old from Bern has climbed three places in the tennis world rankings following his success in Gstaad and is now ranked 70th in the ATP rankings.

In Gstaad he saw off two Spaniards (qualifier Oscar Burrieza and world number 61 Juan Balcells) before losing to the tournament's eventual winner Jiri Novak in the last eight.

Novak was also upwardly mobile on Monday, the Czech climbing seven places up to 33rd following his Swiss victory. Despite losing to Novak in Sunday's final, Spain's Juan Carlos Ferrero went up one spot to fourth.

Swiss number one Roger Federer remained in 14th place on Monday, despite losing his first round match in Gstaad. Of Switzerland's other first round casualties, Marc Rosset actually managed to climb three places to 98th, while George Bastl and Ivo Heuberger fell back slightly to 119th and 135th respectively.

In the women's game, Martina Hingis has clung on to the top spot for at least another week, despite her recent run of disappointing results. Patty Schnyder remains in 33rd spot after finishing as runner up in Austria this weekend, for the second year running.
