Daniil Medvedev engaged in a bizarre act to cool himself down after beginning to feel the ill effects of the heat and humidity at the ongoing 2025 Cincinnati Open. While the act may have helped Medvedev cool down, it eventually turned out to be yet another forgettable outing for the former No. 1, as he crashed out of the ATP Masters 1000 event of the prestigious hardcourt tournament.As the No. 12 seed in the men's singles main draw in Cincinnati, Medvedev received a first-round bye and began his campaign with a second-round match against the unseeded Adam Walton from Australia. The Russian won the first set 7-6(0), but lost the second 4-6. In the third and decisive set, Daniil Medvedev was trailing the Australian 1-4 when a changeover took place. Here, the 20-time ATP Tour-level singles titlist bizarrely buried his head inside a courtside refrigerator in an attempt to cool down amid the hot and humid conditions in Cincinnati. Check out the picture of the moment below:The act was ultimately of little significance as Walton won the next two games to close out the match and oust Medvedev from the Cincinnati Open.
