"Champ of my heart" - Daria Kasatkina's girlfriend Natalia Zabiiako sends her sweet message after Charleston Open final loss

Daria Kasatkina was close to winning her first title on the 2024 WTA Tour at the Charleston Open but came up short against Danielle Collins.

Kasatkina was seeded No. 4 at the WTA 500 tournament and faced reigning Miami Open champion Danielle Collins in the title contest on April 7. Collins, who is playing her last year on the WTA Tour, has been in red-hot form over the past couple of weeks and continued her dominance on the court as she defeated Kasatkina to win her fourth tour title.

Danielle Collins broke Daria Kasatkina two times in either set to win the match 6-2, 6-1 in an hour and 19 minutes. The American saved both breakpoints on her serve to triumph at two consecutive tournaments.

After Kasatkina lost to Collins in the title contest, her girlfriend Natalia Zabiiako sent a heartfelt message to her via Instagram. Zabiiako posted a picture of Kasatkina from the match and said she will always be her champion.

"Champ of my heart," Zabiiako wrote on Instagram.
