Not sure I understand your worst case. Where does Tony Sipp come into it? They could have signed him to a contract extension now, during the 2016 season, at a higher price than $6.5 (like I said, $10-12).. if he continued pitching well, if he wasn't willing to sign that, they could have traded him for prospects. They also have turned to a draft philosophy of picking multiple bullpen arms, so I would hope one of those would be ready to take the reigns in 2017. Unless I'm forgetting something, the next time Terry Ryan signs a vet to contract extension multiple years prior to that vet needing an extension and it works out great, will be the first.
