The latest set of ATP rankings have been released and there have been a few players who have enjoyed a big jump. Reilly Opelka and Kei Nishikori both impressed during their respective tournaments the past week and this was reflected in their recent rankings.

Opelka produced some impressive performances at the Brisbane International and beat Novak Djokovic en route to the final. Here, he played Jiri Lehecka, and the two only played five games before the American was forced to retire due to injury. Opelka's run in Brisbane saw him rise 122 spots to 171st in the ATP rankings.

Kei Nishikori impressed at the Hong Kong Open and beat the likes of Denis Shapovalov, third seed Karen Khachanov, Cameron Norrie and Shang Juncheng to reach his first final in six years. Here, he faced Alexandre Muller and won the first set 6-2. However, the Frenchman bounced back to win the next two sets 6-1, 6-3 and clinch the ATP 250 title.

Nishikori's run in Hong Kong saw him return to the Top 100 of the ATP rankings for the first time in over two years. The Japanese moved 32 spots up to 74th, thus being the best mover among players in the Top 100.

There was just one change in the Top 10 of the rankings, with Alex de Minaur rising a spot to eighth after the United Cup, while Andrey Rublev dropped to ninth after his early exit in Hong Kong.
