British number one Andy Murray has comfortably secured a place in the quarter-finals of the Shenzhen Open in China.

The 2013 Wimbledon champion raced through a 6-3 6-3 win over India's Somdev Devvarman in his first match since he sparked controversy for supporting Scottish independence.

Games went by the way of serve in the early stages of the first set, but Murray broke the deadlock on his fourth break-point opportunity to edge in front.

Another break point was required for the Scotsman to take a one-set lead, but Devvarman was able to break back after losing his first service game of the second set.

However, he failed to keep the momentum as Murray broke again to push on and wrap up the contest.
