 He can defend really well and loves defending. He can also attack. So it's kind of hard to formulate a game plan against him. And it kind of feels like one of those pivotal moments in tennis, like the way Serena Williams revolutionized the women's game with bringing so much more power than there was before, or the way the big three revolutionized it just by how long they were able to dominate. It feels like this is something new that we're seeing. That's sports reporter Ava Wallace of The Washington Post joining us from London. Thank you so much. Thanks.
