Novak Djokovic won a record fourth Shanghai Masters title with a 6-3, 6-4 win over 13th-seeded Borna Coric on Sunday. The 21-year-old beat Stan Wawrinka, Bradley Klahn, Juan Martin del Potro, Matthew Ebden and Roger Federer en route to his fifth title match.
However, since then, his season has unraveled pretty fast. He also fought back when Djokovic held three championship points at 5-3 to claim another game.
Djokovic, a prominent member of the ATP Player Council, said last week he is committed to the rival ATP World Team Cup, set to take place weeks after the Davis Cup at the start of 2020.
The Serb did not drop a single service game in the entire tournament-such was his dominance.
Coric, the 13th seed, upset Roger Federer in Saturday's semi-finals to reach his first Masters 1000 final.
But she has struggled in comparison this year and her China Open defence in Beijing came to a meek end in the last 16, losing the deciding set 6-0 to Aryna Sabalenka of Belarus. "I was playing good, really, I was really happy how I played", he said.
"I think you're seeing the new Novak", he said. "I'm feeling good on the court".
"I found it and I'm just trying to hold on to it as long as I can".
With his win over Coric in the Final, Djokovic now moves up a spot in the rankings to No. 2, taking the position away from Federer who falls to No. 3.
The Serbian former World No 1 continued his scintillating form in 2018, having emerged victorious in two Grand Slams (Wimbledon, US Open) and the Cincinnati Masters, in Shanghai to stretch his winning run to 18 games.
"I have been playing really well throughout my career in China", Djokovic told the crowd.
Coric, who had his right thigh wrapped throughout the match, saved three match points on his own serve in the ninth game of the second set.
Wang - who has been touted by some as a potential successor to Chinese tennis icon Li Na - was chasing her third title but was never in the match, which was over in little more than an hour.
Yastremska is the sixth teenager to advance to a WTA final this year and the second to win a title.
