In the search for a right-handed bat to face those lefties, Bochy had to turn to Cain (.147 career wOBA) and Sanchez (.277 career wOBA, .282 rest-of-season projected ZiPs wOBA) in important moments. The Giants have the second-worst wRC+ against left-handers in the National League (56, the Pirates have a 55). The titular question seems fair: are the Giants too lefty-heavy?
