Have you considered that maybe they're maximizing their skills? Someone like Edwin is likely doing what makes him the best version of himself given his skill set. He's not going to go from a 150 wRC+ guy to a 170 wRC+ guy by looking to flip singles into right field.
Well, now I'm in the awkward position of watching the Jays game, hoping for a Jays win while Trout rakes and Weaver shuts down Edwin, Tulo, Travis, and Pillar.
