Joe Ortiz has a Minnie Mouse Backpack

Yu Darvish lost his perfect game (and no-hitter) on the last batter, but strangely this photo of Joe Ortiz wearing a Minnie Mouse backpack feels like a bigger story to us. Ortiz is a 22-year-old relief pitcher who made the Rangers bullpen out of Spring Training. We snapped this photo off the TV coverage after the game. Does anyone know what the hell is going on with the Minnie Mouse backpack? Rookie hazing perhaps?
