Andy Murray battled to a three-set victory over Argentinian Pedro Cachin to reach the quarter-finals of the Gijon Open in Spain.
As in his impressive first-round win against Alejandro Davidovich Fokina, Murray began slowly and this time had to fight back from a set down to clinch a 2-6 7-5 7-6 (3) triumph.
Murray failed to take his chances in the first set, seeing five break points go begging while Cachin, ranked 61, took two of his three opportunities.
Murray tightened things up on serve in the second and levelled the match, breaking in the 12th game as he converted his first set point.
It remained a battle through the decider and Murray was twice a break down after dropping serve in the first and fifth games before hitting straight back.
Cachin survived some close moments to force a deciding tie-break, where Murray capitalised on his strong start to set up a last-eight clash with either American Sebastian Korda or veteran Spaniard Roberto Bautista Agut.
