Dishonorable Mentions
OF Jason Bay to San Diego Padres for P Jason Middlebrook and P Steven Reed (July, 2002)
Yep, Jason Bay made the list. And yes, the Mets had him both before he was good, and after. His impressive numbers with Pittsburgh and Boston make this trade a bad one: he was the National League Rookie of the Year in 2004 and was selected to three All-Star games.
P Collin McHugh to Colorado Rockies for OF Eric Young, Jr. (June, 2013)
Who would’ve thought Collin…McHugh…would turn into anything?
Apparently not the Mets decision makers, as McHugh was sent to Colorado in exchange for Eric Young Jr. And while EYJ had some success as a Met, McHugh’s emergence as a solid American League starter for the Astros makes this deal a bad one in retrospect.
