LOS ANGELES – Nolan Arenado absently waved a bat over his head while he talked, the sort of thing that happens when there are bats around all the time. He was talking about the Los Angeles Dodgers, who at the moment were a month of games ahead of his Colorado Rockies, a serious problem when there's not a month left in the season. Not a year ago his Rockies stood shoulder to shoulder with these Dodgers, and fell a few runs and about an hour short of being the better team.
