The Greek, who won the tournament in 2019, can become the first-ever player to reach world number one without winning a Grand Slam if things go his way.
His chances are slim, but it’s till possible. He must win the tournament without losing a single match to become world number one. Rafael Nadal, meanwhile, can finish the year on the top of the rankings if he reaches the final after an undefeated round-robin stage, or wins the title.
