Well, I searched the UMDB, which has every Mets player, opponent, and minor leaguer since 1962, and Bruce is the only YI guy. Of course, that doesn't account for the decades before 1962. I think Rabbit Maranville's last name may have ended in YI but it was before my time, so I can't be sure. https://upload.wikimedia.org/wikipedia/commons/6/6e/Rabbit_Maranville_1914.jpg>
