Tennis Star Aryna Sabalenka Smashes Racket After Losing Australian Open, on Video

Aryna Sabalenka won’t win her third Australian Open in a row … and, while she usually wins the break point, she reached her breaking point after the heartbreaking L — taking it out on her trusty racquet.

The Belarusian tennis standout was playing American Madison Keys in the final … and, ended up losing the third set 7-5, dropping two out of three after battling back down 1-0 to force a tiebreaker.

After a hard fought final point, Keys emerged victorious … walking up to Sabalenka to hug — which the superstar did politely, if a bit stony-faced.

While Keys celebrated her victory though, waving to the crowd, the real fireworks began near Sabalenka’s bench … where she repeatedly beat her racquet into the ground before spiking it away.

Watch the clip for yourself … even the commentators sound a bit taken aback.

Sabalenka talked to the press about the blow-up after … admitting it was caused by a bit of frustration — stemming from how close she got to the three-peat.

This is Keys’ first Grand Slam victory … she fell just short of winning the 2017 US Open — losing in the final to Sloane Stephens. Sabalenka — as we mentioned — has won two Australian Opens, and she won the US Open last year as well.
