This match was the first for Murray at the Shanghai tournament this year as he had a bye in round one and was handed a walkover in the second round. His opponent Dmitry Tursunov withdrew due to an injury.
Murray is on great form and the titles in Thailand and Japan from the previous two weeks gave him lots of confidence.
The Brit played some fascinating tennis throughout the first set, but lost his focus in the second. That gave the opportunity to Wawrinka to come back into the match as he broke Murray’s serve to take a 5-3 lead before serving it out.
In the third set, Murray came back strong once again and broke the Swiss right away. From then on, he was in full control of the match and closed it out after winning the third set 6-3.
Murray will next face Matthew Ebden of Australia, who ousted Gilles Simon of France 6-2, 2-6, 7-6 (8).
Spain’s Feliciano Lopez was on fire as he dismissed Berdych of Czech Republic 6-4, 6-4.
Berdych has just won the title at the China Open, where he beat Cilic in the final.
