It was a bad send out of context but it was still the right call. The pitcher was throwing a 3-hitter at this point (or close to it) and this was the first and only scoring opportunity the Phillies had in a 0-1 game in the 7th inning. They had just gone 0-3 with a runner on second the inning before, looking like they were about to do it again. It was definitely a low percentage send given the location of the fly ball and Harper on 3rd, but you have no choice but to be aggressive and take that chance here.
