Novak Djokovic advanced to the semi-finals of the Shanghai Masters with another impressive display and booked a meeting with Alexander Zverev.
The Serb has been in great serving form throughout the week and maintained his focus against the giant South African in a 7-6 (7-1) 6-3 win.
To reduce this performance just to his serve would be unfair. Djokovic looks ominously good in all departments.
Should he defeat Zverev – who earlier beat British No. 1 Kyle Edmund 6-4 6-4 – he will rise above Roger Federer to become world No. 2, regardless of whether the Swiss defends his title.
Of course, Djokovic is setting his sights higher than that as he looks to usurp Rafael Nadal at the top of the rankings by the seasons end. On this evidence, he will take some stopping.
That said, his next opponent is also in excellent form.
Zverev, like Djokovic, has not dropped a set throughout the tournament, while he beat the Serb in their only previous meeting, which also came at Masters 1000 level in the final of the Italian Open.
But after winning Wimbledon and the US Open, Djokovic is once again the most feared player on the planet and it will require a top-drawer performance from the 21-year-old German to stop him.
The first break point chance of the match came the three-time champions way midway through the opening set but was snuffed out by Anderson with an ace.
Djokovic had dropped just five points behind his serve in his first five service games of the match, but was forced to dig deep and save a set point as Anderson looked to pinch the opener.
However, he remained calm under pressure to hold before steaming through the breaker and wrapping up the first with a clean backhand down the line.
A quick break at the start of the second set put the second seed in total control and he made no mistake in seeing out the match.
