Tennis star Jannik Sinner, ranked as number one in the world, is out of the ATP tournament in Halle after losing to Alexander Bublik from Kazakhstan in three sets 6–3, 3–6, 4–6.
The three-time Grand Slam champion took home the first set in comfortable style, but then it stopped for the Italian.
Bublik, known for his hard serve and unorthodox playing style, will next meet the Czech Tomas Machac in the quarterfinals.
