Washington Nationals center fielder Denard Span forgot to bring his jersey on the team's road trip to Kissimmee, Florida to take on the Houston Astros in a spring training exhibition game. As a result, Span had to wear a number 91 jersey for the game instead of his usual number 2, probably because that's all that the Nationals equipment managers had left to give him.
