"The A's are continuing to pursue a deal for Rangers reliever Koji Uehara, according to multiple sources, and a trade might be completed as soon as today.
Uehara could fill Oakland's closer role, vacant since the team traded All-Star Andrew Bailey to Boston, allowing Brian Fuentes and Grant Balfour to remain in set-up roles.
Oakland has a surplus of outfielders, including former Stanford outfielder Michael Taylor and outfielders/first basemen Brandon Allen and Chris Carter."
