Novak Djokovic booked his place in the semifinals of the ATP Finals as the world number one dispatched Alexander Zverev 6-4, 6-1 on Wednesday.
Djokovic, chasing a sixth ATP Finals title and his first in the prestigious season-ending event at London’s O2 Arena since 2015, was guaranteed to reach the last four for the eighth time after Marin Cilic beat John Isner 6-7 (2/7), 6-3, 6-4 in Wednesday’s second match.
The Serb, who beat Isner in his opening group-stage match, has enjoyed a remarkable renaissance in the second half of 2018 and lifting the trophy on the banks of the River Thames would be the perfect way to finish his year.
Assailed by claims he had lost his hunger for success and was past his best after injury and personal issues threatened to derail his career in 2017, the 31-year-old has banished his demons in spectacular style, winning the Wimbledon and US Open titles, returning to world number one and becoming the first player to win all nine Masters 1 000 tournaments.
“I found it more difficult than in the first match against John Isner. I played well midway through the second set and started to swing through the ball,” said Djokovic, who has suffered only two defeats in the Finals since 2012.
“Zverev has a big first serve, but his percentage dropped in the second set. That allowed me to step in. He made a lot of unforced errors which helped me to win.
“I am going to enjoy some quality time with my family and then get ready for the last game in the group.”
Djokovic faces Cilic in his last group match on Friday, while Zverev, who defeated Cilic to kick off his Finals campaign, takes on Isner.
