Let’s predict how each of the ‘next gen’ will do next year and come back at the end of the year to see how we did.
Medvedev- continues his crazy consistency but is still stopped by the big 3 more often than not. Wins a couple more masters and maybe, just maybe wins a slam. I think he has a huge chance everywhere but the French.
Tsitsipas- don’t think it’ll be a big year for him, now that he has been on tour for a bit players have started to figure out his game. He’s broken though, but now this year he’ll learn he still has holes to patch in his game. Predicted finish in the 8-12 range.
Zverev- he’ll get back on track this year, winning a Masters or two. Still don’t think this is the year he wins a slam, though. Big 3 are still very tough and his next gen rivals keep getting better. Will finish in the 4-7 range.
Khachanov- still not convinced he is top 5 material. I do think he’ll be more consistent next year though, could finish in the top 10. Probably not any Masters titles but who knows.
Berretini- has decently backed up his huge USO result which doesn’t happen often with next gen breaking through for the first time. His game is huge, I think he’ll win an M1000 next year and finish top 10.
FAA- think it’ll be another big year for him. He’s taken a beating in the second half of 2019 and knows he has work to do. Depending on how his game evolves, he could start becoming scary good. He’s barely 19, so I’m thinking he has nowhere to go but up. Possible top 10 finish.
Shapovolov- Shapo has posted great results in the final part of this season and takes a ton of momentum into next year. I’m still unsure he’ll be able to have this kind of consistency off of indoor hard, though. Predicting a top 25 finish.
Fritz-I think he’ll continue to rise after this career best year. He’s always had the tools to be great and he’s starting to figure out how to put them together. Top 20 at least
de Minaur- well on his way to becoming the next Ferrer. I’m not expecting him to win anything big but his consistency is fantastic for his age. Top 15 for sure, maybe top 10.
Rublev- he’s been on fire ever since knocking out Federer. I think he’ll get dangerously close to top 10 next year.
Coric- his career trajectory has always been puzzling to me. Some days he looks irredeemably average, and on other days he’s destroying big 4 members in straight sets. This past year was horrible for him. Very few impressive wins, the only reason he‘s still in the top 30 is because his seeding got him sone easy early rounds. Given that, I’m actually going to predict him to drop to the 30-40 range next year.
Tiafoe- another puzzling career trajectory. After reaching his first QF he was basically on a steady downward slope throughout the year. He’s been competitive in matches he just hasn’t been winning them. Terrible deciding set record. I’m going to predict him to finish in the 25-40 range again, though I hope I’m wrong as he has one of the more inspiring stories. Would love to see him win Washington
Hurkacz- HuHu is on the up and up. Top 20 finish next year.
Opelka- it’s crazy how seamlessly he is sliding into the John Isner role. The question is whether he can improve on John’s base level. Top 20 finish for sure, maybe more.
Overall, I think it will be another big 3 dominated year for the most part- each of them has basically perfected their late-career formula for winning.
Medvedev- continues his crazy consistency but is still stopped by the big 3 more often than not. Wins a couple more masters and maybe, just maybe wins a slam. I think he has a huge chance everywhere but the French.

Zverev's 2nd serve game has gone from great strength to tremendous liability. Makes him hard to predict.
