The Mallorca Open has an absolute guarantee: Anastasija Sevastova will play the final. The Latvian completed the treble in Calvià today by reaching her third consecutive final in the tournament, fourth counting the last’s season doubles final.

The defending champion, runner-up in 2016 (lost to Caroline Garcia), won the Australian Samantha Stosur 7-6 (1) and 6-1 in hour and 16 minutes.

Sevastova is just one step away from defending successfully the Mallorca Open crown, which in its short history has had the Latvian as its main protagonist.

In the final, the No. 20 in the world will meet a debutant: Tatjana Maria. The 30-year-old German advanced today to her first WTA final after beating the young American Sofia Kenin in a tough match of almost two hours in which she finally imposed the experience (2-6, 6-2 and 6-4).

“I am very happy to reach my first WTA final. I could almost cry,” Maria said to WTA after the match. “I think it’s the grass, actually. I love to play on the grass. I was really prepared for this grass season to do something good, and I’m happy that I did it already.”
