KANSAS CITY - The Giants opted to keep a second left-hander in the bullpen rather than a third catcher. When they activated Buster Posey from the seven-day concussion list Tuesday they designated catcher Tim Federowicz for assignment.
The Giants lack experienced catching depth and have to hope that Federowicz clears waivers and accepts an outright assignment to Triple-A Sacramento.
Federowicz, 29, spent six games with the Giants in Posey's absence. He started Thursday's 3-1 loss to Colorado and pinch-hit two nights earlier, going 0-for-2 with a walk combined.
Federowicz's partial week in the majors was costly.
