When Giants ace Madison Bumgarner takes the mound at Oracle Park on Wednesday, he won't be facing off against the Los Angeles Dodgers' Clayton Kershaw. While Bumgarner (1-4, 4.30 ERA) will be opposed by Dodgers starter Hyun-Jin Ryu (3-1, 2.96), it's a matchup between pitcher and batter that could be most critical to the outcome. When the Dodgers' Enrique Hernandez comes to the plate for the first time, he will bring with him an astounding track record against one of the best pitchers the Giants' franchise has ever known.
