Andrey Rublev jokingly challenged the chair umpire to a bet over a double bounce call during his second-round match against Matteo Arnaldi at the 2023 Vienna Open.Rublev downed Arnaldi on Thursday, October 26, to set up a quarterfinal clash with Germany's Alexander Zverev. He overcame the Italian in straight sets in their first-ever encounter.The opening set saw a tough fight as both opponents remained inseparable until the 12th game. Arnaldi saved a total of six break points during the set but his opponent eventually broke his serve to secure the set 7-5.Rublev gained control in the following set as he hit nine winners and remained unchallenged on his serve. He clinched a 7-5, 6-3 victory in 86 minutes to reach his 11th quarterfinal of the 2023 season.On a lighter note, the Russian contested the chair umpire at 40-30 in Arnaldi's favor in the fourth game of the second set. It happened when the Italian made Rublev chase a drop shot from the baseline.The World No. 5 believed he made the shot in time before the ball bounced twice but the official felt otherwise. Rublev quickly walked up to the chair and invited the official to gamble on the call."We can have a bet. Let’s do a bet," Rublev said.Luckily for the Russian, the umpire denied the invitation with a laugh, as replays showed the opposite of what Rublev claimed.The video of the conversation between him and the umpire can be watched below:Andrey Rublev trails Alexander Zverev 2-5 in head-to-head countAlexander Zverev and Andrey Rublev greet each other.Andrey Rublev and Alexander Zverev will now prepare to square off for the eighth time, with the German leading the head-to-head 5-2.Zverev is yet to drop a set in the Vienna Open campaign so far.
