Sixth seed Grigor Dimitrov is through to the last four at the ATP Finals in London following his thrashing of Belgian seventh seed David Goffin.
The Bulgarian made it two wins from two in the Pete Sampras Group with a 6-0 6-2 victory over Goffin at the O2 Arena.
Speaking after the match, the tournament debutant, who has proved to be a success so far, said: “You get a few days out of the year that whatever you touch turns to gold, and that was the first set.”
In the other group match on Wednesday, Dominic Thiem of Austria defeated Spanish star Pablo Carreno Busta 6-3 3-6 6-4 in over two hours.
Busta replaced compatriot and world number one Rafael Nadal after the first set of group matches. Nadal pulled out of the tournament following his struggles with a knee injury.
Austrian fourth seed Thiem will next play Goffin for the other semi-final place on Friday.
After his match, Thiem was very pleased to secure his first victory at the tournament. He said: “It was a really, really tight match.”
“I think he took the place of Rafa very well, a very tough three-setter. I’m pleased to be through, got very very tight at the end.” he further stated.
It would be the turn of the Boris Becker Group on Thursday with tennis legend Roger Federer taking on Marin Cilic of Croatia while Alexander Zverev and Jack Sock will face each other to determine who joins Federer in the semifinal.
