Muk, Joyce, Camargo and Riley should be mixed and matched so everyone stays sharp and rested. I understand 2 of them have been getting most of the playing time. Muk because he is the established incumbent. And Riley because he got off to a blazing start. But those four are pretty much equivalent in terms of the value they are likely to provide going forward this season. As it turns out Camargo and Riley are better against lefties and Muk and Joyce better against righties. Platoons in left and right, not necessarily strict ones, might be the best way to go with those four. I'm not a believer in going with the hot hand based on small samples. We are seeing why with Riley and others.
