I don't know how Pittsburgh Pirates fans are going to react to the club trading closer Mark Melancon to the Washington Nationals with the Pirates just three games out of the second wild card, but I suspect not very well.
That's especially true when you consider that since 2013, Melancon has a 1.80 ERA and Aroldis Chapman has a 2.03 ERA and the Yankees got a high-upside shortstop prospect for Chapman, while the Pirates merely got reliever Felipe Rivero and his 4.53 ERA, plus minor league lefty Taylor Hearn.
