Andy Murray eased into the quarter-finals of the Barcelona Open with a straight-sets win over unheralded Colombian Santiago Giraldo.
The second seed wrapped up a 6-1 6-2 victory in just 74 minutes to set up a meeting with Canada's Milos Raonic in the last eight.
Giraldo, ranked 54 in the world, was something of an unknown quantity for Murray with the players having not previously faced each other on the ATP Tour.
The Scot broke his opponent in just the second game when Giraldo fired a forehand into the net, and then held off two break points on his own serve to take a 3-0 lead.
Both players held their next service games, but Murray had the chance to break again in game six and was gifted a 5-1 advantage thanks to an ambitious forehand from Giraldo.
That left the second seed serving for the set, and although the Colombian battled to stay in it, he was unable to prevent Murray wrapping up proceedings in 33 minutes.
Another poor shot from Giraldo handed a further break to Murray at the start of the second set, but the Scot lost his concentration in game four and a weak forehand into the net allowed his opponent to break back.
However, he regained the edge once more in the next game through another unforced error from Giraldo, before breaking once more in the seventh after the Colombian could only find the net with his backhand.
Murray found himself serving for the match and he secured the win when Giraldo's backhand once more let him down.
