It was a hard court tournament, Not grass. Querrey has been around defeating top 10 players once in a while but he's very unpredictable.
Yeah he entered the tournament as unseeded player and defeated 4 top 20 players to win the title , without any doubts he deserved the title . He placed 18 aces in the final which is just great serving and he saved all the break points .
Rafael Nadal never lost a set in Acapulco atp open before, but in this match, he have been broke twice by Sam Querrey. To be honest, Sam Querrey can be quite a class tennis player when he wanna to, just need some kind of inspiration. As for Nadal, I'm lucky I didn't bet on him because the odds are too low. He will be heartbroken, already lost 2 finals in 2017.
