Coming off a deflating loss to the NL West-leading Arizona Diamondbacks, San Francisco Giants manager Bruce Bochy wanted to see signs that the defending World Series champions hadn't packed it in. They haven't. Pablo Sandoval homered twice, lefty Madison Bumgarner struck out a career-high 13 in 8 1/3 innings and the Giants beat the last-place San Diego Padres 7-2 on Monday to remain seven games behind the Diamondbacks with 21 to play.
