Karen Khachanov advanced to the second round at ATP Doha with a 6-1, 3-6, 6-4 victory over Shintaro Mochizuki on February 17, 2026. The Russian controlled the match with a 76% first-serve win rate, overcoming his own error count of 28 unforced errors against Mochizuki’s 45 to claim the opening-round contest in just over two hours on the hard courts.
Khachanov seized control early, racing through the opening set with clinical precision and converting three of his seven break opportunities. Mochizuki regrouped in the second, hitting 24 winners overall and capitalizing on Khachanov’s dip in intensity to force a decider. The third set became a battle of nerves, with Khachanov converting two crucial break points and steadying his serve when it mattered most, winning 92 total points to Mochizuki’s 78.
The match turned on Mochizuki’s seven double faults and mounting unforced error count, which ultimately gave Khachanov the openings he needed. Despite serving seven aces and pushing the Russian on return games, the Japanese player couldn’t overcome his consistency issues when the match hung in the balance.
Key Takeaways
- Khachanov’s first serve was dominant at 76% points won, compared to Mochizuki’s 57%, providing the foundation for victory in a tight three-setter.
- Mochizuki’s 45 unforced errors—17 more than Khachanov’s 28—proved decisive, particularly as the Russian committed just two double faults to his opponent’s seven.
- Despite hitting four more winners than Khachanov (24 to 20), Mochizuki couldn’t maintain consistency when converting break opportunities, winning only 3 of 5 compared to Khachanov’s 5 of 13.
- The 14-point margin in total points won (92-78) understates how competitive the match felt, with Mochizuki storming back to win the second set 6-3 before faltering in the decider.
Player Analysis
Karen Khachanov
The Russian’s serve was the difference-maker, particularly his first delivery, which landed at a respectable 62% and yielded a remarkable 76% points won. Khachanov showed tactical discipline throughout, avoiding the wild swings in form that often plague him and keeping his unforced error count to 28 despite the three-set grind. His ability to convert 5 of 13 break point chances reflected smart court positioning and aggressive returning when opportunities arose.
While his second serve remained vulnerable at just 43% points won, Khachanov protected it when necessary and never let Mochizuki gain sustained momentum in the deciding set. The victory showcased a maturing approach—winning without dominating the winner count (20 to Mochizuki’s 24) but capitalizing ruthlessly on his opponent’s errors.
Shintaro Mochizuki
The Japanese player demonstrated flashes of genuine quality, particularly in the second set where he raced to a 6-3 victory and throughout the match with his 24 winners. Mochizuki’s six aces showed he possesses weapons, but his seven double faults and staggering 45 unforced errors revealed a player still finding consistency at ATP level. Getting only 53% of first serves in play put him under constant pressure, and his 57% first-serve points won left too many doors open for Khachanov.
Mochizuki’s aggressive shot-making kept him competitive—he actually hit more winners than his opponent—but the risk-reward calculation tilted against him as errors mounted in crucial moments. Converting 3 of 5 break points showed capability, yet generating only five chances across three sets against a player seeded higher reflects the challenge he faced on return.
