Karen Khachanov

Karen Khachanov came out of Moscow — Armenian father, Russian mother — and started on a racket as a toddler before turning pro in 2013, the year he claimed the Under-18 European Championship. The climb was unglamorous: a first ATP Challenger title in 2015, a maiden tour title at the 2016 Chengdu Open, then a steady push into the elite that crested in 2018.

At 198 cm, the build dictates the game. Khachanov is a flat-hitting power baseliner whose serve is the engine and whose forehand is meant to end points in two or three swings. He generates pace without much margin, which makes him a brutal front-runner on hard courts and a streaky one when the first serve dips. Fans tune in for the sheer ball-striking — when the timing is on, few players hit through opponents more violently from the back of the court.

The defining run came at the 2018 Paris Masters, where he beat Novak Djokovic in the final for his first Masters 1000 title — still the headline line on his résumé. He has reached two Grand Slam quarterfinals and pushed deeper since, and his career-high of No. 8 confirmed he belonged among the tour's heavyweights. The other crown jewel is Olympic singles silver at Tokyo 2020, a medal that reframed how the tour read his ceiling. His long-standing Davis Cup and junior partnership with Andrey Rublev remains part of the story.

Now ranked 15, Khachanov is the seasoned veteran of a generation that has since been overtaken at the top by Jannik Sinner and Carlos Alcaraz. He remains a dangerous out for anyone in the early rounds of the Masters circuit — a measuring stick the younger wave still has to clear.
