ROTTERDAM, Netherlands (AP) — David Goffin of Belgium eased into the quarterfinals of the ABN AMRO tournament on Wednesday by defeating Feliciano Lopez 6-1, 6-3.
Goffin had nine aces and dropped just two points behind his first serve to extend his unbeaten record against Lopez to 3-0.
The seventh-ranked Goffin, who dispatched Nicolas Mahut in straight sets in his previous match at the indoor tournament, will next face either No. 6 seed Tomas Berdych or Viktor Troicki.
Twenty-time Grand Slam winner Roger Federer later begins his campaign in Rotterdam as he bids to return to the top of the rankings for the first time since 2012.
Federer plays Ruben Bemelmans of Belgium in the first round. If Federer reaches the semifinals, he will replace Rafael Nadal at No. 1.
In other action, second-seeded Grigor Dimitrov beat Yuichi Sugita 6-4, 7-6 (5) and Robin Haase won an all-Dutch contest against Thiemo de Bakker 6-2, 6-2. Dimitrov and Haase were joined in the second round by qualifier Pierre-Hugues Herbert, who advanced after Richard Gasquet retired while trailing 3-1.
