This young man is Bronson Sardinha, a September callup by the Yankees and a native of Hawaii. You can tell he's from Hawaii, because he has the strangest middle name we've ever heard from a Major League Baseball player.
Sardinha's middle name? It's Kiheimahanaomauiakeo. We are heretofore demanding that he change his official player name to Bronson Kiheimahanaomauiakeo. Not only will it make his uniform incredibly entertaining to read — if he leaves the Yankees anyway — but it will make John Sterling's head spontaneously combust.
