Jakub Mensik, a rising Czech talent, stunned Italy’s No. 2 seed Jannik Sinner in the quarterfinals of the Qatar ExxonMobil Open on Thursday in Doha. Mensik delivered an impressive performance, capturing the match 7-6 (3), 2-6, 6-3 by dominating the final set and serving 11 aces.
Strong Service Game Secures Victory for Mensik
