The Atlanta Braves non-tendered Peter Moylan a couple months ago due to his increasing salary and his injuries. He has been a fan favorite for the Braves. (If you are not following him on Twitter, I would recommend it. He is very entertaining). The Braves had expressed interest in bringing him back, but they could not do so at the $2 million + he was set to make, because of budgetary constraints and his injuries.
He was recovering from shoulder surgery that sidelined him late last year. This came on the heals of a back injury that he battled early on.
The deal is a minor league deal worth $1 million on a prorated basis based on time served on the major league roster in 2012. It also has incentives built into the contract.
