Belinda Bencic wondered if she would ever be able to compete for titles on clay but will do exactly that on Sunday.

The Swiss reached her first ever WTA Tour final on the red dirt of the Charleston Open, beating semi-final opponent Ekaterina Alexandrova 6-4 6-3.

Although she has four WTA titles to her name, this was only Bencic's third last-four appearance on clay – losing the prior two, including a 2014 Charleston challenge as a 17-year-old.

But she finally has glory in her sights, and the omens are good for the final, facing Ons Jabeur having won their only prior meeting in 2021 at the Madrid Open, another clay-court event.

"I'm happy this moment came," Bencic said. "I didn't think it would, but I'm super happy with how I played today. I thought it was a great match in tough conditions."

Bencic needed only 78 minutes to complete the job, but Jabeur found life tougher, forced to rally from a set down to Amanda Anisimova.

The 20-year-old American had herself recovered to eliminate top seed Aryna Sabalenka earlier in the tournament but was now on the wrong side of such a comeback.

Jabeur, who lost in the final of the WTA 250 Charleston Open II last year, prevailed 2-6 6-1 6-4.

Meanwhile, at the Copa Colsanitas, there will be no repeat win for Camila Osorio after the defending champion and top seed lost to Laura Pigossi in straight sets in the semis.

Tatjana Maria is now Pigossi's opponent in the title match.
