Madison Bumgarner looks like his old self of late, turning back the clock with a dominating run of pitching for the Arizona Diamondbacks. His latest chance to show he's still an elite ace comes Monday when the Diamondbacks open a four-game series on the road against the veteran's old nemesis, theLos Angeles Dodgers. In 37 appearances (36 starts) against the Dodgers, mostly as a member of the San Francisco Giants, the 31-year-old is 15-14 with a 2.74 ERA in 230 1/3 innings.
