Djokovic targets Slam record at US Open, Sinner under cloud

Novak Djokovic, fired up by his emotional Olympic Games triumph, targets new Grand Slam records at the US Open from Monday as title rival Jannik Sinner arrives in New York dogged by questions over two positive drugs tests.

Defending champion Djokovic can become the oldest Open era champion at the tournament if he secures a fifth title, a record he would share with Jimmy Connors, Pete Sampras and Roger Federer.

The 37-year-old would also move to 25 Grand Slam triumphs, taking him clear of the 24 he currently shares with Margaret Court.

The final major of the year comes at a critical time for Djokovic.

This year he was succeeded as Australian Open champion by Sinner who also relieved him of his world number one ranking.

Carlos Alcaraz took his French Open title with the Spanish crowd-pleaser then sweeping Djokovic off court in a one-sided Wimbledon final.

However, Djokovic, returned to the clay courts of Roland Garros to stun Alcaraz in the Olympic final.
