If Gibson makes the roster opening day, he will be Twins property from 2013-2018. He will have 3 years of serfdom making approximateliy 500k/yr and 3 years of arbitration. If Gibson gets promoted on May 1, he's Twins property from 2013-2019. he will also likely be a Super 2 meaking he has 3 years of serfdom and 4 years of arbitration. If Gibson gets promoted between June and July, he essentially ends up with 4 years of serfdom and 3 years of arb. You cannot say with a straight face that there isn't value in that... especially if he season is lost. The big downside, as I see it is some players know they are essentially being held back for that additional control. In the case of Gibson, he's not a lock to make the rotation, and for all intents and purposes, the season is lost (unless someone honestly thinks Gibson is the difference between playing in October or staying home). And while his peripherals prior to the injury were quite good, he wasn't exactly destroying AAA either. I agree that this is a much bigger deal if it's a Boras client who you know will leave, but it's still a big deal. This has nothing to do with Gibson being good enough or not. It has everything to do with getting an extra year of cost controlled player that will either make for a cheaper long term contract, give you more leverage in buying out some years, or make the player an attractive trade option.
