Reached ITF Junior World No. 19.Consistently performed at a high level but wasn’t dominant — likely due to his impatience with structure and training.

He preferred flair over form.

Coaches noted his “feel for the ball” and creative instincts, especially in doubles and improvised situations.

Even as a junior and Challenger player, Bublik was clocking first serves well over 130 mph with consistency.He led the ATP in aces per match multiple seasons — even ahead of Isner and Karlović.

His motion was loose and unpredictable, but deceptively effective — a natural weapon that needed only refinement.

2017 Wimbledon Qualifying: Bublik hit 45 aces in three matches to reach the main draw as a 19-year-old.

Coaching him is like holding onto a kite in shifting winds.

Some days, he’s all focus, absorbing advice and executing like a pro; other days, he’s improvising shots that look like trick-serves from a street-court exhibition.

The key is not to cage him, but to channel that unpredictability just enough so it works in his favor.

When things get tense, his sarcasm comes out like a well-timed drop volley — light, but with bite.

He’ll crack a joke about his own double fault, make a mock-serious comment about how “clearly the umpire’s chair is tilted,” or deadpan that his last miss was “part of the plan.”

It’s half defense mechanism, half entertainment, and fully part of his game.

Bublik made an immediate impression by qualifying for the 2016 St. Petersburg Open and beating Roberto Bautista Agut (ATP No. 16 at the time).

That win signaled he wasn’t just a trick-shot artist — he could hang with Top 20 players.

"He’s unpredictable in a good way." – Bautista Agut, post-match interview.

Behind the underarm serves and on-court sarcasm was a smart, tactical player.

He often used pace variation, drop shots, and unexpected angles — especially against higher-ranked opponents — to pull off upsets.

2020 Roland Garros: Pushed Gaël Monfils to five sets using nontraditional shotmaking — tweener lobs, sliced second serves, even reverse forehands.

A teenage Bublik doesn’t just play the game — he toys with it. His tactics swing between moments of laser-sharp calculation and “why not?” chaos. One point he’s grinding out an extended rally, the next he’s drop-shotting from three meters behind the baseline. Opponents quickly learn that “predictable” isn’t in his vocabulary, and that’s exactly the way he likes it.
