Novak Djokovic and Andy Roddick won in straight sets on Wednesday to march into the third round of the Paris Masters.

Like many players this week, second seed Djokovic fell behind early on against Argentine Juan Monaco as he took time to adapt to the fast court.

A break down, the Serbian recovered to take the first set 6-4 before wrapping up the second 6-3. He next faces American John Isner or Frenchman Michael Llodra.

Eighth seed Roddick breezed past Finnish qualifier Jarkko Nieminen 6-1, 6-4 to set up a meeting with Latvian Ernests Gulbis.

Roddick is trying to qualify for this month's ATP Tour Finals in London and holds the last remaining spot ahead of Spaniard Fernando Verdasco who won his second-round match in Paris on Tuesday.

"Every match I win is significant at this point ... it puts pressure on the guys behind me," the American said.

"The last thing you want is to be at home cheering against somebody hoping that something bad happens to them."

Roddick fired nine aces as his serve and volley game prevailed on the quick surface.

Marin Cilic came through a tough three-setter against Ukrainian Sergiy Stakhovsky 6-4, 4-6, 6-3. The 13th seed from Croatia next plays world number four Andy Murray or Argentine David Nalbandian.
