I don't get this at all. Varvaro is a solid reliever. He's not a stud, but he posted a 3.21 FIP and 3.15 xFIP. Very solid. Need guys who can give you good performances when you need to rest someone or just don't want a game to get out of hand.
Maybe he's got some kind of knock, but I don't get cutting him, he's still got 1 year beofre he's arb eligible, so we save a few 100K? If we need to clear up 40 man spots I can list several others to cut, How about Costanza? How about one of Pastor or Gosselin? There were other opportunities than to cut our 4th best reliever. We'll have ditched 2 of our 4 best relievers, and added, well Jim Johnson.
Also why aren't we actively pushing Russell on the market, someone needs a quality reliever, no point keeping him around for no compensation.
