9. Celebration Change-Up: Medvedev's video game move accompanies Grand Slam win
Players react in different ways when they win a Grand Slam. Some lift up their arms and roar. Others pump their fists. Some fall to the ground. Daniil Medvedev did none of these things when he won this year's US Open. Instead, the Russian flopped to his side and slumped on the ground before getting up and shaking hands.
It left most of those watching confused, but the gamers knew what he was doing—the FIFA video game goal celebration often performed by soccer players on screen. "Only legends will understand what I did," he said in his winner's speech.
