Bumgarner looks to extend dominance over D-backs

The Giants look to salvage a tough road trip while Arizona hopes to start its homestand on the right foot after losing a series to the Dodgers. Madison Bumgarner, who had the Giants' only win in their four-game Chicago set, has a 1.22 ERA in his last five starts against Arizona. D-backs rookie Braden Shipley will face the Giants for the first time in his eight-game career.
