I'm going to pick Berrios, but like Chief I don't do Twitter so you won't get my vote there. He's been the ace we've desperately needed, providing 112 innings with a sub 3.00 ERA, and his ability to get more innings than the other guys has saved the bullpen from throwing more innings. While Polanco has the higher WAR and on a individual player basis he should be the MVP, without Berrios our pitching staff as a whole would suffered tremendously. It was hard not picking Polanco, I do love this guy. He deserves to be the MVP and All-Star rep.
