Nadal nears return to top spot
Rafael Nadal stayed on track to reclaim the world number one position after beating Philipp Kohlschreiber in the China Open second round.
Nadal, who will regain his place at the top of the world rankings if he reaches the final in Beijing, took one hour and 54 minutes to beat Germany's world number 25, 6-4 7-6 (7/3).
Nadal will next face Italy's Fabio Fognini, who beat wild card Lleyton Hewitt 6-0 6-2.
The Spaniard will overtake current world number one Novak Djokovic even if the Serbian beats him in the final.
