LONDON — (Adds quotes)

By Martyn Herman

LONDON — Novak Djokovic produced a masterful display to outclass South Africa's Kevin Anderson 6-2, 6-2 on Saturday to set up an ATP Finals title showdown with Alexander Zverev.

The world No. 1 was immaculate from start to finish against the 32-year-old as he put himself within touching distance of a record-equaling sixth title at the year-ender.

He offered up a mere 14 unforced errors and not a single break point as he again proved too good for Anderson, who he beat to win Wimbledon this year. Djokovic found his range immediately and the writing was on the wall for Anderson when he dropped serve in the opening game.

Anderson, the first South African to reach the semifinals in the tournament's 48-year history, simply had no answer to the relentless accuracy of Djokovic's groundstrokes and had to save two break points in his next service game.

Breezing through his own service games — he is yet to be broken this week — Djokovic was able to exert maximum pressure on Anderson's delivery and his opponent buckled to drop serve again as Djokovic pocketed a one-sided opener.

There was no let-up at the start of the second set for Anderson as he double-faulted to go 0-40 in his opening service game, Djokovic duly breaking again as the world number six dumped a forehand into the net.

Anderson received a code violation for an audible obscenity but it was hard to blame him for losing his cool as Djokovic continued to turn the screw.

Breaks were arriving with the frequency of London buses for the Serb and a rasping crosscourt forehand gave him another one as he romped into a 5-1 lead.

Should he win against the 21-year-old Zverev, who he beat convincingly in the round-robin stage here, the 31-year-old will become the oldest player to claim the title. Roger Federer, the previous oldest, was beaten 7-5, 7-6(7-5) by Zverev in the day's first semifinal.

American duo Mike Bryan and Jack Sock have the chance to complete a memorable six months together when they play for the title at the ATP Finals on Sunday. Bryan, who has spent a career accumulating doubles titles with twin brother Bob, teamed up with Sock after his sibling suffered a hip injury and the duo have thrived.

On Saturday the fifth seeds beat Jamie Murray and Bruno Soares 6-3, 4-6, 10-4 at the 02 Arena and will take on French pairing Pierre-Hugues Herbert and Nicolas Mahut in the final. Bryan will be seeking a fifth title at the season-ender, but the first without Bob.

Herbert and Mahut, who will be in action for France in next week's Davis Cup final, beat Juan Sebastian Cabal and Robert Farah 6-3, 5-7, 10-5 in the day's second semifinal. — Reuters
