A ton of players have been cross training this offseason with boxing and soccer videos floating around everywhere, but Victoria Azarenka is the first to try baseball. 

It's a natural sport for tennis players given their stellar hand-eye coordination and comfort swinging at moving balls, so it was expected for the Belarusian to be pretty good instantly. Also notice how she went for the lefty swing, which would feel more like a backhand. 

The world No. 51 seems hooked on the age-old American sport, claiming she'll be picking up her own gear next. She's looking to get her 2019 season off to a good start after not really getting off the ground in 2018, finishing with a 17-12 record.
