RACHEL MARTIN, HOST:
Good morning. I'm Rachel Martin. A famous tennis racket is up for sale, and it doesn't even work. It's Serena Williams' Wilson Blade, the one she smashed at the 2013 U.S. Open during a match she lost to Naomi Osaka. It was the crack heard round the world after a dramatic game where Williams got a charge for illegal coaching and got into it with the ref. Williams gave the busted racket to a ball boy. He sold it for $500 to a collectibles store to get some cash for college. Now the store's auctioning it off for a whole lot more. Transcript provided by NPR, Copyright NPR.
