Wednesday night the Boston Red Sox hosted what may be their most popular promotion night ever: more than 10,000 fans (half of whom had never attended a game before) came out to Fenway Park for Fourth Wing Night, inspired by Rebecca Yarros's romantasy series. Ticket holders received a limited-edition Red Sox/Fourth Wing replica flight jacket, and VIP ticket holders also got a special edition of Fourth Wing (Entangled Publishing), featuring baseball stitching and the Red Sox logo. Fans enjoyed themed concessions, photo ops, cosplay, and more. Yarros threw out the first pitch, and the Cleveland Guardians went on to beat the Sox, 8-1. A portion of ticket proceeds went to the children's charity One October. (photo courtesy Boston Red Sox)
