STOCKHOLM (AP)—Fifth-seeded Stanislas Wawrinka cruised through to the second round of the Stockholm Open on Monday by beating Andreas Seppi 6-2, 6-2.

Wawrinka broke Seppi three times to take the first set. He started the second with two consecutive aces and broke Seppi twice more for a comfortable victory.

“It was almost a perfect match for me,” Wawrinka said.

Wawrinka will next face Filip Prpic or Robin Haase.

Swedish wild card Michael Ryderstedt also advanced after beating Daniel Gimeno-Traver 7-6 (3), 6-3. Gimeno-Traver’s eight aces weren’t enough to overcome an opponent ranked 331 spots below him.

Jarkko Nieminen overcame a poor start to beat Michael Berrer 4-6, 6-1, 6-4.

Roger Federer and Robin Soderling enter the indoor hard-court tournament in the second round later this week, as do third-seeded Tomas Berdych and fourth-seeded Ivan Ljubicic.
