After trading breaks twice early on en route to 3-all, Begu took it to a whole new level, reeling off eight games in a row to build a seemingly insurmountable 6-3, 5-0 lead. Sasnovich held at love to stop the streak, but the No.1-seeded Begu then served it out for a 6-3, 6-1 championship victory.
"I think the key today was to stay calm and make my opponent run more, and I think I was successful in those. I was also hitting the balls deep and close to the lines," Begu described. "I also think I was better on the important points - I wasn't dominating every game, but I did better on the big points."
Begu now has two WTA titles to her name, having conquered Tashkent, Uzbekistan back in 2012.
"I'm so happy to win my first WTA title in three years - it's been a long time, and I've improved a lot, I think," Begu said. "I've learned a lot from many matches and many experiences, and most of all I think I've become much more consistent when I'm playing. I feel totally different from three years ago."
Begu was asked how important a win this was for Romania - and how big tennis is back home, too.
"I think it's important because tennis is really famous there right now," she said. "We have so many players in the Top 100, and there are so many fans of tennis back home. They support us so well."
The World No.29 is projected to rise to No.26 now, bettering her previous career-high of No.28.
It was still a fantastic week for Sasnovich too, though - the Belarusian WTA Rising Star battled her way through the qualifying draw and made it all the way to her first WTA final, having not even been to the quarterfinals of a WTA event before. She even took out two of the Top 3 seeds along the way, beating No.3 seed Sloane Stephens in the quarters and No.2 seed Anna Karolina Schmiedlova in the semis.
It was Arruabarrena and Klepac's first WTA doubles title together. Arruabarrena, one of Spain's top WTA Rising Stars, now has five WTA doubles titles to her name, Slovenian veteran Klepac four.
