"Still, if you're going to watch a pair of zombies go at each other for eleventy-billion hours, far into the night, it might as well be these zombies. They were incredible, astonishing, indefatigable. They fell over frequently but they never stayed down. My hat goes off to these zombies. Possibly my head goes off to them too." Xan Brooks' live coverage of Isner-Mahut. Some great writing in there.
