Paris Masters 2018: Roger Federer, Novak Djokovic into Semi-Finals

Roger Federer and Novak Djokovic qualified for the semi-finals of the 2018 Paris Masters on Friday, setting up a dream clash between the two titans on Saturday.

Federer took care of Kei Nishikori in two sets, while Djokovic needed a third against Marin Cilic. As shared by TennisTV, Djokovic continued an impressive run of wins in the process:

Karen Khachanov and Dominic Thiem will meet in the other semi-final. Here are Friday's results:

(3) Roger Federer bt. (10) Kei Nishikori: 6-4, 6-4

(2) Novak Djokovic bt. (5) Marin Cilic: 4-6, 6-2, 6-3

Karen Khachanov bt. (4) Alexander Zverev: 6-1, 6-2

(6) Dominic Thiem bt. (16) Jack Sock: 4-6, 6-4, 6-4

Cilic played some of the best tennis he's played all year to make life hard on the in-form Djokovic and shocked everyone by claiming the opening set. As shared by the ATP World Tour's official Twitter account, the Serb hadn't dropped a set in some time:

Cilic took full advantage of Djokovic's issues with his own serve, and those troubles persisted throughout the contest. The Djoker responded with some superb work from the baseline to grab breaks of his own, however, ultimately bagging the win.

After the match, Djokovic told reporters illness is to blame for some of his struggles:

He'll have to heal fast to have any chance against Federer, who played very efficient tennis against Nishikori and picked his spots for a routine win.

His first break came late in the first set when the Swiss switched gears in the rallies. Winners like this one made the difference:

That break was immediately followed by another early in the second set, and Federer easily served things out from there.

Elsewhere, defending champion Sock bowed out of the tournament against Thiem, and per tennis writer Christopher Clarey, the loss will have unwanted consequences in the world standings:

Khachanov's superb form continued against Zverev, as he made mincemeat of the German. Zverev was out of sorts and even got visibly upset at his opponent at the end of the first set for some reason, but the two hugged it out at the end of the contest.
