The Oakland Athletics traded 2012 All-Star right-handed relief pitcher Ryan Cook to the Boston Red Sox for a player to be named later, reports Jon Heyman of CBS Sports and the Bay Area News Group's John Hickey. There is no word yet on the return. Cook, 28, got off to a terrible start and never returned to form to merit a return to the club despite Oakland's bullpen woes.
Oakland Clubhouse's Melissa Lockard has one guess as to who the player to be named later might be:
Total speculation based on nothing but my guess, but perhaps the PTBNL is Daniel Nava, currently on release waivers.
