Big left-hander Madison Bumgarner is staying put with the San Francisco Giants, who instead determined their bullpen depth provided them the best place to make trades before Wednesday's deadline. Milwaukee acquired left-hander Drew Pomeranz and righty Ray Black from San Francisco for infield prospect Mauricio Dubon. ''We are pleased to add a veteran presence in Drew Pomeranz and a high-velocity arm in Ray Black to the organization,'' Brewers president of baseball operations and general manager David Stearns said.
