One can only wonder if the Mets relief corps had their collective ears at the door Thursday morning as Sandy Alderson stood outside the clubhouse expressing his frustration at watching this so-far uplifting season at Citi Field suddenly being sabotaged by another leaky pen. Barely 12 hours earlier, Alderson had unceremoniously jettisoned D.J. Carrasco, minutes after the righty reliever surrendered a two-run homer to Cincinnati Reds third baseman Todd Frazier, and now the Mets GM was threatening more changes. "The bullpen has been a frustration," Alderson said. "We made a lot of changes to it in the offseason and, to this point, it hasn't worked out as we had hoped. The guys we have won't pitch like this the rest of the season. That's our expectations."
