I gather it's an MLB-wide issue, depressed outfielder offense (or, perhaps, a preference for defense?)
Bellinger has the third-highest OPS at .784, not what $27.6 million is supposed to buy you. Then it's Conforto, Hernandez, Tatis Jr. and Marsh.
I missed one guy above .800, Heliot Ramos (guess I should have voted for him).
Duvall and Rosario both awful. And Corbin Carroll's a bigger problem than Rojas still.
Better modest trade options on the AL side though the presumably not-modest Arozarena is at .591 OPS.
Matt Vierling has been having a good season.
