American John Isner was having a disastrous start to the 2018 season but then caught fire at Crandon Park and completely turned his year around. The 32-year-old defeated German Alexander Zverev in the Miami Masters final to claim his maiden Masters 1000 glory.

Isner entered the Miami event with just one win and six losses at the ATP level this season. Prior to Miami, the American's lone wins this year came against Radu Albot in the Delray Beach first round and Serb Dusan Lajovic in a Davis Cup rubber, respectively.

Isner, who now has 13 ATP titles in his collection, was previously 0-3 in his Masters 1000 finals. The big-serving American won six matches on his way to winning it all at Miami - - a run which included wins Juan Martin del Potro, Marin Cilic and rising Hyeon Chung.

Isner also rose to No. 9 in the world following his successful Miami run. The American is now just a step away from reaching his new career-high ranking. The 32-year-old climbed to the No. 9 spot for the first time in his career in 2012.

Isner has always been performing well at the Masters events - - but was constantly falling to win a Masters 1000 title - - before he captured one when he was least expected to do so. A-now-confident Isner will forget his bad start to the year as he will now be eager to continue his success and try to further improve his ranking, as well as try to put himself in the best possible position to land a Grand Slam glory at one of the remaining Major events in 2018.
