The world's No. 1 player surged through the first set in 19 minutes in a commanding tuneup for the May 24 French Open, the clay-court major Hingis has yet to win.

The quick work by the 18-year-old Swiss prompted one spectator to yell, ``Not so fast, Martina.''

Hingis completed the rout in 42 minutes for her fourth title this year and the 23rd of her career.

On Saturday, Hingis played excellently in defeating French Open champion Arantxa Sanchez-Vicario 6-4, 6-0.

Hingis earned $150,000 for winning the German Open, a tournament in which she had failed to last beyond the quarterfinals in three tries.

The draw for the $1.05 million tournament was depleted by injuries and upsets after starting with 16 of the world's top 20 players.

Halard-Decugis, playing her first final after winning five minor events, will rise to 16th in the rankings.
