The Giants might be unwilling guests at the Dodgers’ division-clinching celebration when they play four games in Los Angeles starting Sept. 12. Before tonight’s play, the Dodgers led second-place Arizona by 12 games. After that series, the Dodgers will have 13 to play; Arizona will have 14 to play. So if the Dodgers stay hot, and Arizona doesn’t rally, the Dodgers might have the pleasure of clinching the west and having an on-the field celebration while the Giants watch. It will be interesting to see what Giants manager Bruce Bochy does with his pitching staff and lineup for those four games. If it means spoiling or at least delaying a party until the Giants leave town, you would expect that Bochy won’t put a Scottsdale spring training lineup out there for the Dodgers to run over. The Giants have little to play for, so keeping the Dodgers’ champagne on ice might be the best incentive.
