Top seeds Novak Djokovic and Andy Murray both enjoyed straight sets victories in the third round of the Mutua Madrid Open on Thursday.
World No 1 Djokovic absolutely steam-rolled over Spaniard Roberto Bautista-Agut, dismissing the 15th seed 6-2, 6-1 in just 69 minutes.
The Serb broke serve twice in the first set and three times in the second to wrap up the most straightforward of wins.
Murray, meanwhile, was similarly convincing in his 6-4, 6-2 victory over Gilles Simon.
While Simon was the first to apply pressure in the third game of the first set, forcing Murray to deuce four times in a row, the Scot survived the onslaught before gradually gaining the ascendancy.
A late break in game 10 handed Murray the first set and two further breaks in the second saw Simon surrender the match rather tamely.
Fifth seed Rafael Nadal also enjoyed smooth progress later in the day, beating Sam Querrey 6-4, 6-2, while sixth seed Kei Nishikori was another to reach the last eight.
The Japanese star faced a tricky third-round match against 10th seed Richard Gasquet, but managed to win the points that mattered on the way to a 6-4, 7-5 victory.
Elsewhere, while Tomas Berdych defeated clay court specialist David Ferrer 7-6 (10-8), 7-5 and Australian Nick Kyrgios advanced with a hard-fought 7-6 (7-5), 4-6, 6-3 win over Pablo Cuevas.
