BASTAD, Sweden - Saturday proved twice as nice for Misaki Doi at the Swedish Open.
The Japanese left-hander not only won her second career WTA 125K series singles title over Danka Kovinic on the Swedish clay, but followed that up by winning the doubles title with Natalia Vikhlyantseva over Kovinic and Alexa Guarachi.
Doi defeated three seeded players en route to Saturday's final - beating No.4 seed Mona Barthel, No.7 seed Elena Rybakina and No.8 seed Aleksandra Krunic in the second through semifinal rounds - before she handled Kovinic in just over 80 minutes, 6-4, 6-4.
In their first-ever meeting, the World No.117 rallied from a break down in the first set against the Montenegrin No.1, who went 0-for-4 on break point opportunities in the games following her first break of the Japanese woman's serve.
Kovinic saw one chance slip by in the sixth game, but rued three straight missed chances in the eighth, where Doi held from 0-40 down to lead 5-3.
In the second set, both players were forced to defend break point opportunities on their serve, but late missed chanced for the World No.162 once again decided proceedings.
After saving a break point in the set's opening game, Kovinic stayed ahead for nearly the duration, and held two more break points on Doi's serve which would have seen her lead 5-3 if converted.
Returning to the court alongside Vikhlyantseva for the doubles final, Doi and her Russian partner came through a marathon championship match against the No.2 seeds, 7-5, 6-7(4), 10-7, to allow her to pull off the double.
The unseeded duo nearly let a 5-2 lead in the first set slip away, before they broke serve for a fourth time and held to love for a one-set lead.
Guarachi and Kovinic again battled back from a deficit to send the final to a match tiebreak, however, as they came from a break down and won the last five points of the ensuing tiebreak to extend the championship.
From there, however, the Japanese and Russian pair took an early lead and hardly let go, as they won the first three points on their seeded foes' serve in the tiebreak to ultimately come through with a victory.
The 28-year-old from Japan improved to 3-0 in WTA 125K doubles finals with the win, and won her first WTA 125 singles title in three years.
