From the Pioneer Press' Mike Berardino:
Former Twins pitchers Deolis Guerra and Hector Carrasco also underwent the procedure, which involves the partial removal of a rib to relieve nerve and circulation issues in the throwing shoulder area.
The hope -- expectation? -- is that this will solve Hughes' shoulder fatigue issues. He was already out with a leg fracture, but now he won't be back until spring training 2017.
Also from Berardino: Max Kepler got a fairly high-level rebuke last weekend from Reggie Jackson, who watched the rookie take aim at the right field seats during batting practice in Yankee Stadium and told him: "I'm 70 years old and I can do that. Let me see you go the other way."
I'll bet Kepler hears that from Tom Brunansky and Rudy Hernandez a lot. Hearing it from a 500-homer Hall of Famer apparently had some influence on the German.
Only one Twins prospect named to the Futures Game rosters Tuesday, J.T. Chargois. I'm mildly surprised at one; there are a handful of others I would have thought worthy, such as Tyler Jay or Stephen Gonsalves.
Nobody gets more than two on the initial rosters, and there are a few teams that only get one. It's possible that the Twins declined to send one of the lower level prospects across the country to San Diego.
