You might be familiar with the Korda family. There's Petr Korda, who won the 1988 Australian Open and peaked at No. 2 in the world. His daughters Nelly and Jessica are both title-winning LPGA golfers, and his son, Sebastian, is a rising ATP star who won the 2018 junior Australian Open.

Sebastian Korda is also extremely talented at keeping a ball bouncing in the air. Even before the coronavirus pandemic put a halt to normal activities and all sporting events, the 19-year-old was showing off his precise talent, which included foot touches.

During the quarantine era of 2020, Korda has stepped his bounce game up. First by winning the Toilet Paper Challenge with a strong 28 count.

And more recently, by knocking off 600 hits with a ball.

Korda was ranked No. 224 after reaching the fourth round of the Indian Wells Oracle Challenger, which was the last event before the tours suspended all play until June.
