Profile: Sean O'Sullivan is bad. His career 6.01 ERA and -1.8 WAR are the worst among pitchers who threw at least 300 innings since he debuted. You know the old adage: Give me average major leauge stuff and I guarantee I'd be a number-one starter. O'Sullivan, a former third-round draft pick, is the antithesis. He signed a contract with the Korean Baseball Organization's Nexen Heroes, so now he has the unique opportunity to be the worst pitcher of an era in multiple professional baseball leagues. That's a hell of an epitaph. (Alex Chamberlain)

The Quick Opinion: Sean O'Sullivan is historically bad. It's no wonder his initials (kinda) spell out S.O.S.
