Jeff Keppinger hit a two-run double, Madison Bumgarner won for just the second time in six starts and the San Francisco Giants held off the Houston Astros 2-1 on Friday night. Bumgarner (8-12) hung tough as he waited for his team to finally give him some support, outpitching J.A. Happ (4-15), who lost his fourth straight start a day after being recalled from Triple-A.
