# Tennis: Reigning champion Daniil Medvedev is through to the semifinals of the ATP Finals in Turin, Italy. The Russian defeated Alexander Zverev, 6-3, 6-7, 7-6, as he secured the top spot in the Red Group, after Italy’s Matteo Berrettini withdrew due to injury. Meanwhile, Italian Jannik Sinner, who replaced Berrettini, defeated Poland’s Hubert Hurkacz, 6-2, 6-2, on his debut at the ATP Finals, to keep his hopes of qualifying for the semi-finals. Sinner could reach the last four if he defeats Medvedev in their next match, or if Zverev loses to Hurkacz tomorrow.
