WATCH: Victoria Azarenka joined by son Leo in adorable post-match interview after Charleston Open 2R win

After her second-round victory at the Charleston Open, Victoria Azarenka’s son Leo made a surprise appearance during her post-match interview.

The Belarusian joined the WTA 500 tournament after a strong performance in Miami, where she made it to the semifinals before ultimately falling in a three-set match against eventual runner-up Elena Rybakina.

After receiving a bye in the first round, Azarenka began her clay-court swing at the Charleston Open with a 6-1, 6-2 victory over Elisabetta Cocciaretto in the second round. Following the match, the two-time Grand Slam champion was joined by her son Leo during her post-match interview with Tennis Channel.

When questioned about her experience of having him accompany her on tour, Azarenka revealed that although she was initially anxious about his presence in the stands, she now thoroughly enjoys it.

“It’s really amazing for Leo first of all to come to come to my matches. I used to be really nervous for him to be out there, but now I feel like he’s watching me. Hopefully he gets a little bit inspired for his sports,”Azarenka told Tennis Channel.

She admitted that her son’s presence provides her with “additional motivation to put in more effort”.

“It gives also extra motivation to like for me to cheer, to try harded, not that I need it, but I do appreciate the ability that he’s able to watch me at work,”Azarenka continued.

In 2016, the Belarusian woman welcomed her son Leo into the world with her former boyfriend Billy McKeague. However, after Wimbledon in 2017, the couple ended their relationship and became involved in a custody dispute over Leo.

Serena Williams withdraws from Charleston Open due to illness, Azarenka and Townsend set to battle in 3rd round

Following her victory over Elisabetta Cocciaretto, twelfth seed Victoria Azarenka is scheduled to face off against hometown favorite Taylor Townsend in the third round of the Charleston Open.

The American began her campaign in Charleston with a 6-3, 6-3 victory over fellow countrywoman and doubles champion at the Miami Open, Sofia Kenin. She followed this up with a 7-5, 6-2 win against Ekaterina Alexandrova, who was seeded sixth, in the second round.

Azarenka and Townsend have not yet played against each other in a professional match, making their head-to-head record 0-0. Whoever emerges victorious in their upcoming match will move on to face either top seed Jessica Pegula or Magda Linette in the quarterfinals of the Charleston Open.
