The Swiss will take a healthy points lead of nearly 900 into the US Open, where No 2 Djokovic is defending the title, starting on August 27.
ATP calculations show that the 31-year-old Federer will maintain the top spot through the end of the season’s last Grand Slam.
Cincinnati Masters champion Roger Federer with his trophy
He began his record 292nd week atop the table yesterday flushed with his fifth career title in Cincinnati from as many finals.
It was his 16th win in 28 meetings against Djokovic and it means he will go into New York as the clear favourite having become the first man to win five titles at the Cincinnati event. The Swiss described his effort as “another amazing week”.
“I’ve had a magical summer (seventh Wimbledon title, London Olympic silver medal). I feel good about New York — but I’m going to savour this one for a bit.
I’ve been able to win five. It’s obviously incredible because I remember the first few here I struggled.
“Now looking back it’s just unbelievable. Plus this was probably the best week ever here in Cincinnati for me never dropping my serve and beating Novak in the final. This was very sweet. No doubt about it.” —
