Metonymy / Synecdoche – Fox Sports Tweet

Screen Shot 2015-02-23 at 7.30.28 PMOne of those classics metondoches (should I add this to the portmanteaux list…?) that could go either way. As a metonymy, the bat of course suggests the power behind it, if not the batter himself. As a synecdoche, the bat is a part of the batter. If I were forced to choose, I would say that metonymy is the stronger interpretation, but either one works. What do you think?
