Alexander Zverev started his ATP Finals campaign in Turin with a commanding 6-4, 6-4 win over Andrey Rublev. The German, a two-time champion, secured a crucial break in each set and didn’t face a break point, continuing his strong season after a Paris Masters victory. Zverev now ranks second in the John Newcombe group.
Earlier, Casper Ruud upset a struggling Carlos Alcaraz 6-1, 7-5, marking his first win over the Spaniard in five meetings. Alcaraz cited fatigue and illness affecting his performance, while Ruud capitalized on errors to earn his 50th victory of the season.
