This is what Primates mean by a
LOOGY, a Left-handed One Out GuY. If you were looking for something else, please go here.
The term was coined (or at least popularized) by former STATS Inc. writer John Sickels.
The patron saint of the LOOGY is Jesse Orosco, though if it weren't for Tony LaRussa, many question whether LOOGYs would exist in the first place.
