In the biggest upset of the tournament, 18-time Grand Slam victor Roger Federer lost 6-3 6-7 6-7 to world number 116 Evgeny Donskoy of Russian Federation in the second round of the Dubai Duty Free Tennis Championships on Wednesday.
Verdasco, the 2009 Australian Open semifinalist, beat sixth seed Roberto Bautista-Agut in an epic three set battle (6-4 3-6 7-5) that lasted two hours and 25 minutes.
Federer netted a forehand on Donskoy's one set point in the second set tiebreaker to extend the match to a third set.
The Scot booked his place in the quarter-finals with a crushing 6-2 6-0 win over Guillermo Garcia-Lopez and he will now take on Philipp Kohlschreiber. "I think whoever wins against Roger surprises himself", said Donskoy 26.
The initial excitement in the match occurred with Federer leading 6-3, 3-4 - when one set of the court floodlights went dark.
With that win against the talented but erratic Spaniard, Murray entered the quarterfinals keeping his hopes of a maiden Dubai title alive. I'm certainly playing better than I did at the start of the year.
Though starting off strongly, at times Federer hardly looked to be the player with 18 Grand Slam titles to his credit as the Russian took his chances with some impeccable shot-making to guarantee a quarter-final meeting with Frenchman Lucas Pouille.
Garcia-Lopez did put up a fight until the first three games of the first set before completely losing the plot. I felt exhausted all day.

GM, on the other hand, is happy to see Opel go after losing the company money for the last 16 consecutive years. Citing an unnamed source, Reuters says board members for PSA approved the deal today.
The top-ranked Briton needed only 72-minutes to bypass the 97th-ranked Garcia-Lopez, saving the one break point he faced on serve at 30-40 in the first game of the match.
"When I got the early break, pretty much was nearly 30 minutes in and we'd only played four games", Murray said.
"Mentally, that was important for me, you know, to be up at that stage".
"I played very well". The German was a 6-4 6-4 victor over Dannil Medvedev of Russian Federation.
"It was a great match", said Monfils. "He plays with a lot of spin".
Gael Monfils held off Britain's hard-charging Dan Evans with a gutsy 6-4, 3-6, 6-1 victory.
The Dutch caused a major upset on Wednesday by beating Tomas Berdych of the Czech Republic 6-3 3-6 4-6 in his second round match.
