SAN FRANCISCO -- It used to be a Madison Bumgarner start meant the San Francisco Giants almost assuredly would find the win column.
Now, still without a 2017 victory, MadBum just wants to get back in a groove and stop giving up costly home runs.
Jhoulys Chacin outpitched Bumgarner, Cory Spangenberg hit a go-ahead two-run homer in the seventh inning that chased the Giants ace lefty from his first home start in more than three months and the San Diego Padres beat San Francisco 5-2 on Thursday night.
