OAKLAND -- Brandon Moss is back, and with him comes a lefty reliever to an A's club that was in dire need of one.
Dealing from an area of surplus, the A's sent right-handers Jesse Hahn and Heath Fillmyer to the Royals on Monday evening to acquire Moss and southpaw Ryan Buchter, thus completing their offseason to-do list.
Buchter gives Oakland a second lefty in the bullpen next to Daniel Coulombe, becoming the third reliever to join the team this winter. The A's added right-handers Emilio Pagan and Yusmeiro Petit earlier in the offseason as part of efforts to bolster their relief corps.
