Harrison finally managed to break Isner early in the second for a 2-0 lead, only for his opponent to immediately break back.
Harrison then saved a championship point in game 12 before earning a set point two games later.
As in the first set, he responded with a big ace to deny his opponent.
Isner then sealed the match and the title in the second tiebreak with a forehand winner up the line.
