Prince tennis ambassador John Isner says his win in the ATP Masters 1000 Miami Open was the “best moment of my career”. The 32-year old beat Alexander Zverev of Germany in a 2 ½ hour final to win his first major title – the biggest victory in his 14-year career.

The fact that #14 seeded Isner was the first American man to win the tournament since Andy Roddick in 2010, resulted in widespread media coverage. According to Prince, the online reports about the win resulted in 277-m impressions.

Following this win, Isner is back in the ATP Top 10, ranked #9. He is the highest-ranked American player on the ATP Tour.

Isner has been using Prince throughout his career and currently plays with the Prince TexTreme Warrior 100 racket, which was ranked #1 all-around frame by Tennis Magazine in 2016. During 2015 he assisted the Prince Research & Development team by play-testing several prototypes to develop the right combination of technology, fit and feel for him.

The tall (6’10”) player holds the record for the fastest serve ever in the Davis Cup, which was clocked at 157.2 mph. His best-remembered feat, however, is the 11-hour match in which he defeated Nicholas Mahut at the 2010 Wimbledon Championships – to date the longest match in professional tennis history.
