Plucky qualifier Miyu Kato produced an epic comeback to advance to her first WTA Tour final on Saturday night, beating Croatia's Jana Fett 4-6, 7-6 (7-1), 6-4 in the semifinals of the Japan Women's Open.

Kato, ranked No. 171 in the world, survived match point in the second set before going on to win the 2-hour, 53-minute match at Ariake Colosseum and will now play world No. 100 Zarina Diyas of Kazakhstan in Sunday's final of the $250,00 hardcourt event.

Diyas shocked defending champion Christina McHale of the United States in the first semi 6-4, 0-6, 6-3.
