“Today it’s me, tomorrow it will be another ballplayer.” That was the message from Mariners shortstop Jean Segura, who recounted in an Instagram post Thursday how he was assaulted and robbed by cops in his native Dominican Republic. The post, written in Spanish, explains how the 27-year-old was stopped by armed officers, who hit him and threw him to the ground before taking his belongings and crashing into his vehicle.
