When a nine-year-old hockey player named Sebastian Korda traveled with his father Petr to the US Open in 2009, it was love at first sight. Until that point, Sebastian had played hockey five days a week, and would hit tennis balls possibly once on the weekend.

When the Kordas returned from that trip, Sebastian approached his father.

“He said he does not want to play hockey,” the former World No. 2 remembered. “He quit hockey overnight. He has not skated and he has not played hockey since. Not once.”

And now, more than seven years later, Sebastian is into the final of the Australian Open boys’ singles, 20 years after his father won his lone singles Grand Slam trophy on the same court inside Rod Laver Arena.

“It’s pretty awesome. It’s a great feeling,” Petr said from his home in Bradenton, Florida. “I’m very happy for him. He’s enjoying his experience in this special journey.”

Petr, who won 10 tour-level singles titles and 10 tour-level doubles titles, did not choose tennis for his kids. In fact, he has two daughters — Jessica, 24, and Nelly, 19, who play professional golf.

“I never wanted my kids to play tennis,” Korda said. “We’d love our kids to play other sports so they can set their own goals. If any one of our kids would follow our footsteps, the goals are already pre-set for them. It’s very difficult for the kids to get out of the shadow of that and obviously they’re trying to beat their parents.”

That is true especially for this tennis-rich family, as Petr’s wife, Regina, was also a professional tennis player, who ascended as high as World No. 26. But while Petr did not want his son, 17, pushed into a life of his father’s choosing, Sebastian made the choice for himself.

“We gave him one month to think about it and during the period he came up to me. I believe Jim Courier was on TV commentating and he came and asked me, ‘Dad, do you know who won the first US Open’?” recalled Korda, who was unsure. But Sebastian knew it was Arthur Ashe, and that proved plenty to Petr.

“That’s when he convinced me he really wanted to play, he was really interested about the history because I love the history of tennis, so he earned my vote to let him go on to be a tennis player.”

It wasn’t just that one nugget that Sebastian knew. Petr remembers Sebastian treating the annual ATP World Tour media guide like a textbook, reciting results whenever players he saw in the book played on television.

“That was like a bible to him,” Korda said. “He became very invested in tennis and that’s what I love and admire and it reminds me of when I was a kid. I could see the passion… That was his choice, his idea.”

From following his father to Flushing Meadows as he coached Czech veteran Radek Stepanek to meeting Roger Federer — who plays for a 20th Grand Slam title Sunday — on the same grounds at 14, Sebastian has lived a fan’s dream in the tennis world.

That passion has carried Sebastian to as high as No. 6 in the junior rankings. He arrived in Australia in December to play play two weeks of ATP Challenger Tour events (reaching the final round of qualifying at each) and an ITF Grade 1 Juniors event. In this week’s Australian Open junior semi-finals, the seventh seeded Korda defeated second seed Marko Miladinovic, whom he lost to less than two weeks ago despite holding two match points.

And now Korda has a chance against Taiwan’s Chun Hsin Tseng, the sixth seed, to become the third member of the family to win an Australian Open title — his oldest sister, Jessica, won golf’s version at age 18 in 2012. Petr coaches Sebastian, but he did not make the trip to Australia. The USTA’s Dean Goldfine and Korda’s former agent, Patricio Apey — who works with Alexander Zverev — are with Sebastian at Melbourne Park.

“I would love to be there, especially 20 years later, it’s very special for me,” Korda said. “But I decided to stay home to let him enjoy the Australian Open the way he needs to enjoy it. If I would be there, I believe I would be a distraction because that trip would not be about him, it would all be about dad’s 20th [anniversary].”

This is all about Sebastian, and Petr values his children’s success far more than his own.

“Lifting my trophy was a fantastic moment, it was a great feeling, but what my kids are doing is what makes me very proud,” Korda said. “Winning [the] Australian Open 1996 doubles and 1998 in singles is meaningless compared to what my kids are doing.

“I’m happy that he is doing his own footsteps, so hopefully he’s not going to be known as my son. Hopefully I’ll be known as only his dad. I think that’s something that I’m really looking forward to. That he’s not going to be reminded what his dad did, but I will be reminded what my son did. I’m really looking forward to that.”

Petr has spoken to Sebastian after each of his matches, but only texted him beforehand. His advice ahead of Saturday’s final will be simple.

“Just enjoy it. Just enjoy it. That’s a great experience. Whatever happens, happens, but enjoy the moment.”

From Florida, Sebastian will have at least one sleep-deprived fan following very closely in the middle of the night as he attempts to become the first American Australian Open boys’ singles champion since Donald Young in 2005.

“It’s very worth it,” Korda said. “But trust me, it’s nerve-wracking.”

Opportunity is knocking at Melbourne Park, and either the pair of Oliver Marach/Mate Pavic or Juan Sebastian Cabal/Robert Farah will seize that chance Saturday evening to claim their maiden Grand Slam title at the Australian Open.

Marach and Pavic, the No. 7 seeds, entered the tournament on fire and have kept the momentum going at the year’s first major. The Austrian-Croatian duo captured its second and third ATP World Tour titles as a team at the Qatar ExxonMobil Open (d. Murray/Soares) and the ASB Classic (d. Mirnyi/Oswald) in the first and second week of the season, respectively.

And the duo will be able to rely on experience in a Grand Slam final as well. Last year, they fell in an epic five-set marathon in the Wimbledon final against Lukasz Kubot and Marcelo Melo, losing 13-11 in the fifth set, making that the second-longest fifth set in a Wimbledon doubles final in the Open Era. John McEnroe and Michael Stich won the 1992 championship 19-17 in the decider against Jim Grabb and Richey Reneberg.

“Losing the Wimbledon final will help us a lot,” Pavic said. “We already have some experience from that. We’ve been there already once, so looking forward to the match.”

Marach and Pavic are battle-tested, too. Not only do they enter the final unbeaten in their past 20 matches dating back to last season, but they have won four three-setters at Melbourne Park, including two in third-set tie-breaks in the quarter-finals (d. Daniell/Inglot) and semi-finals (d. McLachlan/Struff). They have yet to face match point in the tournament.

“It’s exceptional what they’re doing this year. To win already two [ATP World Tour] 250 tournaments, to come out here and back it up with a [Grand Slam] final already,” Farah said. “We just have to focus on our tennis and hope for the best.”

On the other side of the net will be a Colombian team that has had no such difficulty advancing through the draw. Cabal and Farah have yet to lose a set at the year’s first major, and have not been broken since the event’s first round, when the 11th seeds lost serve twice against home favourites Marc Polmans and Andrew Whittington.

“It’s amazing. It’s great for Colombia,” Cabal said. “It’s been an amazing run. We’ve been playing better and better every time.”

Cabal and Farah, who have teamed since 2010, advanced to their first Grand Slam final when they defeated six-time former Australian Open champions Bob Bryan and Mike Bryan for the fourth consecutive time in their FedEx ATP Head2Head rivalry in the semi-finals.

“This team is very underrated,” Marach said. “They have beaten all the top teams, and just a little bit missing to get to the Top 10… will be a tough match, but we know we’re going to get chances.”

The winners will earn 2,000 ATP Doubles Rankings points and claim their share of $700,000, while the runner-ups will capture 1,200 points and split $350,000.

His fairy tale run Down Under ended in the pain of blisters on Rod Laver Arena on Friday night, but Hyeon Chung is taking nothing but positives out of his semi-final showing at the Australian Open.

With Roger Federer’s plaudits ringing in his ears as he left the court – “I think he’s going to achieve next level excellence – Top 10 [in the ATP Rankings] for sure.” – the 21-year-old South Korean said he is leaving Melbourne with a lot of confidence.

The Next Gen ATP Finals champion had toppled Novak Djokovic and Alexander Zverev en route to his maiden Grand Slam semi-final, but was unable to bring his best against Federer as blisters took their toll. In his post-match press conference, Chung’s agent, Stuart Duguid, explained, “It’s worse than regular blisters. Over the last few days, it was blister under blister under blister. He had it shaved off. Now it’s red raw.

“They tried injections to see if it numbed the pain. It didn’t work. Much worse than a regular blister. Because he has played so many matches in the row, I think that’s why it was a build-up. I think that’s how they started.”

“[I was] really honored to play with Roger in [the] semis [of a] Grand Slam,” said Chung. “I’m just learning a lot. He played really good today.

“I think [I took] a lot of confidence. I played a lot of good players in the last two weeks. I can play more comfortable on the court with the great players like Roger. I think I can play better next time,” added the South Korean, who has made history at home and garnered huge national interest with his run at Melbourne Park.

“I really didn’t know I’m going to make it in semis,” said Chung, who is projected to reach a career-high in the ATP Rankings of No. 29 on Monday. When asked if would have to re-evaluate his goals already for the 2018 season, the right-hander responded, “I think I already made a few goals, because I make highest ranking in Korea, highest result in Grand Slam. I made two goals. Next goal is I want to finish the season without injury. I have to recover well.

“I’m just trying to enjoy all the time. I’m just trying my best in the future.”
