Andy Murray became the fourth man to qualify for next month's season-ending championships as he defeated Jeremy Chardy 6-3 6-4 to reach the quarter-finals of the Shanghai Masters Thursday.

Fellow qualifier Novak Djokovic continued his red-hot form in China, with the two-time Beijing champion hammering Richard Gasquet 6-1, 6-1 to leave France winless from two matches on another rainy day.

Murray joined Rafael Nadal, Roger Federer and Djokovic in making up half of the field for the elite eight-man ATP season wrapup from November 21 in London.
