The star of the Little League World Series, Mo’Ne Davis, who already has a complete game shutout in her first pitching appearance, may became an even bigger star for one eBay seller. CrossingBoard got the scoop that one seller has put up a signed Davis ball for sale on eBay, and selling it for over $500. Darren Rovell tweeted that Davis‘ autograph was selling for under $200 just three days ago. Davis pitches tonight against Nevada.
