Mike Trout EV Box by Pitch Type
This is a box plot to demonstrate how hard Mike Trout hits balls based on pitch type. Its easy to see the medians of each pitch type batted balls. Based on this chart, it looks like your best bet is to throw Mike a cutter. Again this only takes in consideration batted balls and its possible/likely that Mike whiffs higher at other pitches. But as far as getting the weakest contact- it looks like a cutter.
