Nick Kyrgios Silences His Critics With Mexican Open Win

Nick Kyrgios has won his fifth ATP title, taking out the Mexican Open against world number three Alexander Zverev in straight sets, 6-3 6-4.

Kyrgios, who is ranked 31st in the world, has had a big week against players ranked much, much higher than himself.

Rafael Nadal and John Isner -- ranked second and ninth in the world respectively-- were brushed aside, while Andres Seppi and three-time Grand Slam winner Stan Wawrinka also fell victim to the Australian.

But Kyrgios has not just had to contend with big-named opponents this week, but a decidedly hostile crowd as well.

After serving an underarm ball to Rafael Nadal in the second round, Kyrgios made himself Public Enemy Number One in Acapulco.

Nadal took a swipe at the Aussie and said the move showed a lack of respect to players and fans.

For his next matches, the crowd booed and jeered at Kygrios.

During his semi-final clash with the American Isner, Kyrgios seemed to win over the fans by taking part in a Mexican Wave that was going around the Mextenis Stadium.

It seemed a turning point for fans in the tournament, and Kyrgios enjoyed a more positive level of support on his way to the final against Zverev.

After pocketing the opening set in the final, and breaking Zverev in the first game of the second, Kyrgios briefly lost focus to gift the German a foothold in the match.

From 30-love up, Kyrgios berated himself for double-faulting on break point down as Zverev looked to be building momentum.

Zverev conjured two more break points with Kyrgios serving at 1-2 but, after surviving, Kyrgios continued to frustrate Zverev with a series of well-disguised drop shots.

In breaking Zverev from 40-love up, Kyrgios also broke the second seed's spirit as he forged ahead 4-2.

There was no way back as Kyrgios sealed victory in one hour and 30 minutes, ensuring a rankings rise from No.72 to 43rd on Monday, as well as a $US367,630 ($A519,000) pay day.
