Left-hander Madison Bumgarner is scheduled to make the first home start since his infamous dirt bike accident when the San Francisco Giants open a four-game series against the San Diego Padres on Thursday night. Right-hander Jhoulys Chacin is slated to get the ball for the Padres to open a series of the bottom two teams in the National League West. The Padres won two of three against the Giants when they met last week in San Diego.
