David Goffin looked like a man that was ready to duck out of London after getting demolished by Grigor Dimitrov, but the Belgian bounced back with a 6-4, 6-1 victory over Dominic Thiem on Friday.
With the win, Goffin has secured a spot in an ATP Finals semifinal meeting with Roger Federer. Thiem, meanwhile, is heading home for the offseason.
This is a crushing blow for the Austrian, who led 3-0 in the first set. The 24-year-old looked to be in total control of the match, but he then appeared to mentally check out. Goffin would hold serve and then break Thiem right back. From there, the Belgian cruised to a victory.
