MONACO (AP) - Jurgen Melzer of Austria and Paul-Henri Mathieu of France both won in straight sets to reach the second round of the Monte Carlo Masters on Monday.

The fifteenth-seeded Melzer broke Polish player Lukasz Kubot's serve five times en route to a 6-2, 7-5 win, while Mathieu took a little over an hour to thrash Donald Young 6-0, 6-1.

Mathieu did save four break points of his own, but he broke Young's serve six times and clinched victory when the American sent a heavy forehand long.

Melzer faces Marcel Granollers of Spain or Frenchman Julien Benneteau in the second round.

Mathieu next plays No. 12 Kei Nishikori of Japan or Spaniard Albert Ramos, runner-up Sunday at the Grand Prix Hassan II tournament.
