The second-seeded South American, champion last weekend in Vienna after returning from a month away with a left wrist problem, will Sunday face the winner from top seed and five-time champion Roger Federer and fellow Frenchman Paul-Henri Mathieu.

"It was almost perfect today," said the South American who has now beaten Gasquet in five of their six meetings, including three in 2012.

Del Potro swept up the opening set in 31 minutes and traded breaks with Gasquet to start the second, But the second seed escaped for a 5-2 lead and turned in his finishing serving performance with minimal effort against an off-form opponent.
"I was a little tired, and I was serving poorly," said Gasquet. "He was making great returns.

Gasquet, playing his first Basel, is chasing one of two remaining spots in the year-end finals in London starting November 5.
He goes to next week's Paris Masters needing top performances from the start after a first-round bye. He stands 10th in the points race with two more positions in the eight-man field still open.

The 2008 Basel semi-finalist has won a career-best 61 matches this season and extended his current win streak to eight matches.
