When the Miami Marlins flipped Yunel Escobar to the Tampa Bay Rays for Derek Dietrich following the infamous 2012 season, the consensus seemed to be that the Marlins had sold low on the erstwhile Blue Jays shortstop, who was a year removed from a 3.5 fWAR campaign.
Indeed, Escobar would put up 3.6 fWAR for the Rays in 2013, before checking in with a -0.1 fWAR contribution in 2014 and subsequently being shipped off to the Oakland Athletics. Derek Dietrich, he of the so-called low return nature, has been good for 4.
