Tamara Zidansek rallied from a set and a break down, then saved four match points to outlast Nadia Podoroska of Argentina 4-6, 7-6 (3), 7-6 (3) in the quarterfinals of the Thailand Open in Hua Hin.

The Slovenian needed three hours and 41 minutes to complete the feat, making it the fourth-longest match of the season in a WTA main-draw event, Podoroska, up 5-4, 40-0 in the third set, had three match points, but Zidansek broke serve after winning an 18-shot rally. Serving for the match at 6-5, Podoroska couldn't cash in on the opportunity, with Zidansek hitting a return winner to fight off the match point.

In the semifinals, Zidansek -- who has fought injuries and illnesses over the past two seasons -- will face Rebecca Sramkova of Slovakia, who beat Croatian Jana Fett 4-6, 6-4, 6-1.

In the other semifinal, Germany's Laura Siegemund will play Arianne Hartono of the Netherlands. Siegemund ousted Rebeka Masarova of Spain 6-3, 6-4, while Hartono beat Mai Hontama of Japan 4-6, 6-2, 6-3.
