JEDDAH: As American teenager Learner Tien wrapped up a four-set victory over Arthur Fils on Friday to reach the semifinals of the Next Gen ATP Finals in Jeddah, his next opponent, Alex Michelsen, rose to his feet on the sidelines to applaud his good friend and point to a message printed on the back of his sweatshirt: “Victory Royale” — a nod to the hours he and Tien have spent playing the video game Fortnite together.

“We play a lot together. So it’s kind of a joke,” Tien told Arab News in Jeddah on Friday. “Our agent got us tracksuits that say it on the back. We both got different colors.”

Tien and Michelsen share more than just a love for video games and matching tracksuits. They have trained at the same academy in Irvine, California for the past four years under the tutelage of Jay Leavitt and Eric Diaz, and share the same agent, Mats Merkel of IMG.

Their friendship will briefly take a backseat when they square off in Jeddah on Saturday evening, as they vie for a spot in the final at the prestigious 20-and-under tournament.

“It’s really cool I think,” said Tien. “I’ve been telling him that we are going to play at this tournament for a while. We’ve played, obviously, before, but never at the professional level. I think he’s 2-1 on me in singles. He tries to count doubles and say it’s 4-1, but I only count singles; so he’s up one on me right now.”

Despite missing three months of action earlier this season due to a fractured rib, Tien has amassed a 62-13 win-loss record over 2024 across all levels, including a trio of titles on the Challenger Tour.

He started the season ranked 473 in the world and hit a career-high mark of 114 last month to position himself as one of the top Next Gen players on the men’s professional circuit.

When he returned from his injury layoff in May, he won a stunning 28 matches in a row across six different tournaments, setting the tone for a strong finish to the season here in Jeddah.

“I think a lot of things changed for him mentally when he got injured,” Diaz told Arab News on Friday. “He matured a lot, started working a lot harder, taking things a little bit more seriously — not that he didn’t prior, but you could see the maturity level change. He diligently worked, diligently analyzed what he needed to get better at and he really went after it.”

This isn’t the first time Tien has benefitted from taking a break from tennis. When the pandemic shut down the tour in 2020, it came at a time where Tien needed some time away from the sport to be a regular young teenager, although ‘regular’ might not necessarily be the right word, since during that hiatus, Tien managed to graduate from high school at the age of 15.

At 16, he won his first of two USTA U18 National Championships and at 17 he attended the University of Southern California for a semester before deciding to turn pro.

Asked if starting high school when he was just 11 years old helped him make such big leaps in professional tennis as a teenager, Tien said: “I honestly did all that early just because my mom was a teacher, so she started me in school early. I really didn’t want to, but I’m glad she did it now. Obviously, it’s great to have all that stuff out of the way so I can just focus on tennis, like I’ve wanted to for a while. Having school, there was an incentive for me to play tennis instead. I’m truly grateful that she started me young, but I definitely didn’t enjoy it.”

Although Tien always knew he was good at tennis — a sport he was introduced to by his parents — he admitted he “didn’t love it” early on.

“(But) I thought I’d put so much time into it already, it would be kind of a waste just to stop. I thought that when I was 10 or 11. Thought that even more when I was 13 or 14, like, ‘Oh, I’ve played even longer now, it will be a bigger waste if I stop now,’” he reflected. “Then, I eventually found that love for it and it’s taken me to where I am today.”

He says the breaks he took during the COVID pandemic and his injury this year have helped him “reset” and made him appreciate the sport even more.

“Obviously taking time away from tennis, you end up missing it a little bit, so when you come back, you’re a little bit more motivated and it’s kind of easier to go out there day in, day out, just because you’ve been away for a while,” he said. “I think that really helped — especially this year. Coming back, I was a lot more motivated to practice harder and work on a lot of things that needed some work and it inevitably ended up helping me a lot.”

This is the first time Tien has competed in a tournament outside the US at the professional level and he’s excited to continue that trend when he heads to Hong Kong for the official start of his 2025 season, before flying to Melbourne for the Australian Open.

Previous Next Gen ATP Finals participants and champions have gone on to achieve great things on the tour, with the likes of Carlos Alcaraz and Jannik Sinner both claiming Grand Slam titles and topping the world rankings not long after their participation.

“I think it’s cool to know that you’re following in their footsteps, going down a similar path to people that have had so much success — even recent winners having a lot of success,” said Tien.

“It’s definitely cool to feel like you’re doing the right thing and you’re taking the right steps to get to that level someday. But I don’t think there’s any pressure that comes with it.”

As he looks to enjoy his first full season at the ATP level in 2025, Tien is bracing himself for change, knowing he’ll be facing new challenges. Not only will the competition level get higher, he’ll also have to learn to adjust to a different calendar that features multiple surface changes, and a great deal of international travel.

His coach Diaz believes stepping up physically will be key for this next chapter of Tien’s tennis journey.

“The jump from the Futures to the Challengers, the difference is the physicality. And then the jump from the Challengers to the main tour is obviously physicality. Learner definitely has the footspeed, the hand speed… but continuing to develop and to become a man, he’s going to have to get stronger,” said Diaz.

Michelsen, who is a year older than Tien, has already made that leap to the ATP Tour and is ranked a career-high 41 in the world.

Diaz is aware both Tien and Michelsen will likely be facing off at tournaments more often moving forward, which will be an interesting dynamic given they share the same team.

“It’s really cool. Both Jay and I, it’s honestly something we never really thought would happen years ago when we started all of it. It’s a surreal moment,” said Diaz, looking ahead to the semifinal in Jeddah.  

“Both of those boys have worked incredibly hard. They’ve pushed each other to get better and to improve. So to be on a stage like this now — and to have a guarantee one of them is in the final — is a pretty cool moment.

“Hopefully it does continue to happen, because I think that means they’re both continuing to push each other to get better. It would be an interesting thing. I’m not sure that either one of them would be there if it wasn’t for the other one. We’re big (believers that) iron sharpens iron. So it’s gone well.”
