Spaniard Albert Ramos-Vinolas dumped world No.1 Andy Murray out of the Monte Carlo Masters in the round of 16.
Albert Ramos-Vinolas fired back from 4-0 down in the final set to take his place in the quarter-finals with a 2-6 6-2 7-5 victory.
Murray, who suffered an elbow injury in March and made his return from a five-week layoff this week after a first-round bye, won the opening set in 48 minutes before losing concentration.
Left-hander Ramos-Vinolas, ranked 24th in the world and the 15th seed, ripped through the second set in 36 minutes and refused to give up after Murray went two breaks of serve up in the deciding set.
The Spaniard won four games in a row before Murray, his serve misfiring, applied some late pressure but Ramos was implacable as he won the next two with back-to-back breaks and served for the match.
