Every team has one, right? The lefty specialist, I mean. The guy who comes on, faces one batter for an instant platoon advantage, and in the blink of an eye is back on the bench. The guy you can miss between commercials if you channel-surf. The guy whose day-to-day performance is defined by a handful of pitches.
The LOOGY (left-handed one inning guy) is not a position from which stars are born. One can certainly carve out a nice career in this role, but teams do not exactly shell out millions for a pitcher with this label. Even that name lacks intimidation; “lefty specialist” just sounds like the medical definition for the disease known as the LOOGY.
