Plouffe went 1-for-4 with a sixth-inning solo homer in Wednesday's 4-2 loss to the Orioles.
By this point in his career, we pretty much know who Plouffe is as a hitter -- he's got the pop and the lineup slotting to hit 20 homers and clear 80 RBI (which he's done twice in his career already), but is a batting-average liability who won't add any speed. There's a place for those contributions in deeper formats, but if he's starting at third base for you in a 12-team league, that's less than ideal.
