Andy Murray crashes out in last 16 of Zhuhai Championships with defeat to Aslan Karatsev

Andy Murray blew an early lead as he crashed to defeat against Aslan Karatsev in the last 16 of the Zhuhai Championships in China.

Murray claimed the first set against his world No 63 opponent, but Karatsev fought back to punish the Scot's inconsistent serve and win 4-6 6-3 6-2.

It was the first meeting between Murray and the Russian since they faced each other in last year's final of the Sydney Tennis Classic, a match which Karatsev won in straight sets.

But Murray put himself in a strong position to exact revenge after saving four early break points and going on to fashion two breaks and take the opener.

Murray had jetted to China on the back of helping Great Britain into the Davis Cup quarter-finals, and he beat wild card Ye Cong Mo in the opening round on Thursday.

And fatigue possibly began to take its toll as Karatsev put himself in a dominant position in the second set, going 4-1 up. Despite a mini Murray revival, he held on to level the match.

Karatsev stepped up a gear in the decider, reeling off two consecutive breaks to take a 4-0 advantage from which Murray never looked likely to recover.
