Dominic Thiem was outclassed by Kei Nishikori at the Vienna Open, while Roger Federer was out of sorts but victorious.
Kei Nishikori ended Dominic Thiem’s hopes of a home win at the Vienna Open to boost his ATP Finals chances, while Roger Federer stumbled into the Swiss Indoors Basel semis.
Thiem was aiming to become just the third Austrian to win the title in his homeland but was completely outplayed by Nishikori in a 6-3 6-1 defeat.
Nishikori hit just 10 unforced errors in a match lasting under 70 minutes, and he now moves up to ninth in the ATP Race To London rankings ahead of John Isner and just a spot behind Thiem.
With three places remaining for the season-ending showpiece, Nishikori will look to further boost his chances by beating Mikhail Kukushkin in the semi-finals after the Kazakh needed three sets to defeat Marton Fucsovics.
Kevin Anderson is up to sixth in the London rankings. The big-serving South African was leading Borna Coric 7-6 (7-2) 1-2 when his opponent retired with a left-foot injury.
Fernando Verdasco is up next in the semi-finals, the veteran Spaniard having also benefitted from a retirement with Gael Monfils unable to complete their quarter-final.
In Switzerland, Federer moved a step closer to a ninth title albeit he was out of sorts in his 7-6 (7-1) 4-6 6-4 beating of Gilles Simon.
The 20-time grand slam champion needed two and a half hours to get the win and recorded a startling 60 unforced errors against the Frenchman.
Will Roger lift No. this week?
