LONDON, Nov. 15 -- Grigor Dimitrov beat Belgian David Goffin in straight sets to book a semifinal berth of the ATP Finals at the O2 Arena here on Wednesday.

The sixth seed stormed to a 6-0, 6-2 win against world No. 7 Goffin in only 74 minutes, joining six-time winner Roger Federer as the only two singles players who have secured semifinal places.

"I think clearly I played a great match today," Dimitrov said. "I think my focus was very good. I started the match well. I was using every opportunity. I took care of all of the balls that I had to. I won the most important points, especially in the first set."

Goffin, who upset world No. 1 Rafael Nadal in his first match scored his first point 48 minutes into the match after being blanked in the first set. But Dimitrov continued to press him all match, charging the net and winning most of the points.

"I'm feeling okay. It was not the problem today. It was just a tough, tough match against Grigor, who played really well," Goffin said.

"It was not easy for me to lose my serve from the start. It was tough for my confidence after that when it was 0-4. In the second, I had some opportunities to come back, to break back, but he was really solid. He served well."

Goffin still has a chance to qualify for the semifinals if he beats Austrian Dominic Thiem on Friday.
