Rafael Nadal continued his serene progress into the quarter finals as he saw off Alexandr Dolgopolov in straight sets.
The world number two is yet to drop a set in Indian Wells this week, his first tournament since that epic Australian Open final in January.
His clash with Dolgopolov had the potential to be a tricky match as he is known for his unpredictable play.
Nadal raced to a 4-1 lead in the opening set and while Dolgopolov did up his game towards the back end of the set he was never able to get back on level terms, Nadal took it 6-3.
Into the second set and Nadal broke through the Dolgopolov serve on two more occasions before sealing the 6-3 6-2 win.
The Spaniard, who is looking for his first title of 2012 in Indian Wells, saw off all five break points he faced throughout the match.
Speaking to the BBC after the match Nadal said: "He is very difficult to play against.
"He can produce winners from every part of the court. He's a funny player, good for tennis."
And he will now face David Nalbandian in the final eight as the veteran player saw off Jo-Wilfried Tsonga in three sets.
It was Nalbandian who made the brighter start to the match as he broke Tsonga in the opening game before consolidating to take a 2-0 lead.
But the Frenchman came rolling back to five of the next six games - and with it the set 6-3.
Tsonga served for the match at 5-4 in the second set. He double faulted on match point to let Nalbandian back into the game to level at 5-5.
And the Argentinean didn't let the opportunity pass him by as he took the next two games to level at a set a piece.
Nalbandian dominated on serve in the decider and come through 3-6 7-5 6-3.
