Unseeded Querrey upsets Nadal in final

Unseeded American Sam Querrey stunned second-seeded Rafael Nadal 6-3, 7-6 (7/3) on Saturday to win the ATP Mexico Open and end the Spaniard's run of perfection in Acapulco.

Querrey, ranked 40th in the world, fired 19 aces, backed up by powerful, precise groundstrokes, en route to his first career victory over Nadal in five meetings.

The Spaniard, the 2005 and 2013 champion, had never even lost a set in Acapulco.

"I'm ecstatic," Querrey said. "To do it against Rafa makes it even a little sweeter."

Querrey captured his ninth ATP title in an impressive week that saw him beat four top-10 players -- Belgian David Goffin, Austrian Dominic Thiem, Australian Nick Kyrgios and sixth-ranked Nadal.

He's projected to return to the top 30 in the world rankings on Monday.

"It's definitely a tournament that I'm going to remember for the rest of my life," Querrey said. "It's one of those weeks where I got in the zone and everything was working for me. I hope I can have more like this.

"After the match against Goffin, I knew I could go far here if I continued to play at that level," he added. "My forehand and backhand were great and my serve bailed me out of trouble when I needed it."

Nadal, playing his first tournament since falling to Roger Federer in five sets in the Australian Open final, was denied his first hard court title since Doha in 2014.

Querrey surrendered just four points on his serve in the opening set and he broke Nadal at love to seize a 5-3 advantage.

“He played very well, almost reaching perfection," Nadal said. "I played under a lot of pressure because of his serve and baseline game. He left me with very few options, and the few I had he also played good."
