Zumaya had an MRI today that revealed he sustained a torn ulnar collateral ligament during his throwing session on Saturday. A torn UCL means he will need Tommy John Surgery and will miss this season. This is the worst possible news the Twins could have received. It looks like their gamble to sign Zumaya as their right handed set-up man has failed and they will need to look elsewhere to fill that role. Terry Ryan said today that they will stay in house for replacement. He is open to the right trade but no one specific in mind.
