Sebastian Korda is coached by his dad Petr Korda, Dean Goldfine, and Theodor Devoty. While that sounds like a lot of coaches for an up-and-coming player, it’s not unusual for players to have multiple coaches.

Sebastian Korda’s dad, Petr, was his primary coach during his junior days and still leads the coaching team. Korda started working with Dean Goldfine in 2017. Goldfine helped Korda win the 2018 boy’s title and helped Korda transition from the juniors to the professional tour.

Korda also works with former Czech tennis player Theodor Devoty.  Korda trained with Steffi Graf and Andre Agassi prior to the 2021 season.

Goldfine is a veteran tennis coach. He coached Andy Roddick, Todd Martin (who reached the US Open final), Xavier Malisse, and Mary Joe Fernandez.

Both of Sebastian Korda’s parents are tennis players. His dad, Petr, won the 1998 Australian Open and his mom  Regina Rajchrtová is a former Top 30 player in the world. His two sisters – Jessica and Nelly – are both professional golfers on the LPGA tour.

Quietly, Tallon Griekspoor is putting together quite a season on the ATP Challenger tour. In 2021, he has won seven Challenger titles – a feat no player has achieved before. He is also on a 20-match winning streak.

He has moved up to world number 72 in the rankings. In 2022, he may not play on the Challenger tour as his ranking will be high enough to get a direct entry into most ATP tournaments. Looking forward to 2022, Griekspoor said,

I have had a good time on the Challenger Tour but I think it’s time for the next step, playing ATP Tour events. I am really looking forward to that and can’t wait to start.

He reached the second round at the 2021 US Open where he lost to Novak Djokovic. Though he lost that match in straight sets, his talent was evident.

Griekspoor’s twin brothers Scott and Kevin, who are five and a half years older than him, also played on the ATP tour. They reached a peak ranking of 205 and 655 in the world respectively. Both his brothers have retired from tennis.
