Federer's struggles were evident early on, despite Nihiskori needing to win a tiebreak before salting away the opening set on Centre Court.

Things were harder still for Federer in the second, as Nishikori attacked the 37-year-old's serve. Federer earned a break of his own to gain some hope:

.@rogerfederer, @keinishikori get back on serve after trading breaks to start the second. But can six-time #NittoATPFinals champion 🏆 Federer stay the course on serve? #ATP https://t.co/ROuzzQJ51s

However, his dangerous opponent kept on breaking back:

Nishikori BREAKS @keinishikori breaks to take a commanding 7-6(4), 4-2 lead against six-time #NittoATPFinals champion @rogerfederer. Will Nishikori finish it in two? #ATP https://t.co/nG5IUO6KF4

Nishikori's latest break left Federer on the brink. He couldn't cope with Nishikori's range of shots, while he also failed to deal with a fairly routine serve as Federer didn't break once during the first set.

Some of Federer's key shots let him down, with his forehand leading to more than a few unforced errors, including for the decisive point.

It all added up to an unwanted piece of history for the 20-time Grand Slam champion:

Roger Federer suffers his first ever straight sets defeat in the group stages of the ATP Finals, losing 7-6 6-3 to Kei Nishikori.

In the day's opening fixture, Anderson took on Thiem, and it quickly became apparent the South African was in fine fettle:

"Beautifully done!" 💫 Kevin Anderson takes on Dominic Thiem in his first-ever ATP Finals match, where he currently leads the Austrian! Watch live on Sky Sports Arena now! https://t.co/rInF6n7RYK https://t.co/ovpgah6BK3

Soon after, he claimed the decisive break in the first set after a double fault and an unforced error from Thiem handed him two break points.

A hold to love consolidated his lead, and he had served out the opener in 41 minutes.

Tennis commentator and writer Jose Morgado was impressed:

José Morgado @josemorgado

Tremendous first set from Anderson 15 winners 10 UE 11/11 at the net. Thiem didn't even play too bad.

The second set was a tighter affair, with Thiem holding his first four service games to love to keep Anderson at bay.

His opponent was similarly resolute, though, and the pair inevitably reached a tiebreaker.

Reem Abulleil @ReemAbulleil

Anderson winning 90% of his first-serve points (dropped just 4 points on his 1st serve). Will try to wrap the win against Thiem in this 2nd set tiebreak.

In a suitably close tiebreaker, Anderson came out on top after Thiem had saved three match points.
