TEMPE, Ariz. — People like Justin Bour. You might say he is a fungus. Still, the first days with a new team can be fraught. The former Marlins and Phillies slugger spent his first days at Angels spring training taking his physical, organizing his locker and introducing himself to his teammates. I’m Justin, he’ll say, or Call me J.B. He stops there. He does not reference the other term by which he is sometimes known, the phrase that has made it to the most official of sources (his Baseball-Reference page), perhaps the most magnificent moniker ever conferred upon an athlete: Bourtobello Crushroom.
