Considering who is pitching and the conditions I support the call. It also puts the Cubs in a position to send Ramirez on a close play since there's already an out. Like I said, you don't want to bunt when you more than likely need two hits to score a run anyways given the speed of the baserunner. Even with the conditions, if there's a smaller chance of the runner on second scoring on a single, it's probably not worth it.
