ATP Finals : Thiem Topples Federer In Opening Group Match
Roger Federer's pursuit of a seventh ATP Finals title got off to a poor start when the Swiss great lost 7-5, 7-5 to Austrian Dominic Thiem in his opening group match.
From the Moment Federer dropped his opening Service game he never seemed entirely comfortable and Thiem took full advantage to claim his third win over Federer this season.
Federer recovered the early break but a couple of lazy strikes at 5-5 cost him his serve again before Thiem closed out the opener in confident fashion.
Thiem, beaten by Federer in the group stage last year, upped the power in the second set to keep Federer under pressure and unable to dictate and pounced again to break at 5-5.
Federer saved one match point in the following game and had a break point but there was no escape and Thiem pummelled away a forehand to claim victory and join Novak Djokovic at the top of the group after the Serb earlier beat Matteo Berrettini.
