If someone tries to get Dunn to raise his average, he's going to start swinging at pitches he shouldn't, and as a result, making more Outs. He just doesn't get enough pitches to hit where he's at in the lineup, so this strategy would be especially bad. He would be driving in those runs if he were actually higher up in the order. He just draws the BB where he's at because he doesn't get enough to hit. I'd rather him BB than record an Out.
