Plural: Unknown; currently impossible to determine
This is a small gem, shaped like a ... well, a small gem. Or home plate. It's an emerald, which is nice, but considering the sport and all you're a little confused why it's not a diamond.
It commemorates the time you kept the Boston Stranglers from preventing opening day. Looks like you're batting a thousand against those Stranglers. Heh. Heh heh.
