After yet another lousy outing, Madison Bumgarner fumed his waythrough the Giants' weight room. Veteranreliever Jeremy Affeldt saw the pained expression on Bumgarner'sface and pulled him aside. His message: Don't worry, kid, we've all been there. "It can be frustrating, shocking, but it's part of the growingpains," Affeldt said after the Giants lost 4-1 to the AtlantaBraves on Friday night to keep Bumgarner winless in April. "It'snever happened to him before, but it's going to happen."
