Something else the dunn"Haters" seem incapable of realizing is the following: Using deductive reasoning, why do you think Dunn's BA is lower when there are RISP? Does he all of a sudden become a different player?!!!
How often is Dunn given absolutely nothing to hit with a RISP in the hopes that he'll either get himself out or walk and allow the pitcher to raise the percentage of achieving a desired outcome SUBSTANTIALLY by facing a substantially weaker offensive player?!
Dunn can't control what pitchers are willing to give him. They know how deadly he is. When there are runners in scoring position, the pitches that he will see and what the opposing pitcher views as a "desirable outcome" changes SUBSTANTIALLY.
