I would say you should replace Rios, Marrero and Crisp. You might want to maintain a flex spot, which could be used to pick up and drop hot players.
As for pitching, you're good on closers, but I would get rid of Jimenez. Sure he gets saves, but he kills your ERA and WHIP. Also, I think if you can unload Burnett on someone for a pitcher who's having a decent year, then do it. I think that pitchers struggle in the first year back from injury, and Burnett is no exception.
I never smile if I can help it.... Showing one's teeth is a submission signal in primates. When someone smiles at me, all I see is a chimpanzee begging for its life.
