The specifics are unknown, though according to Saxon: "That Mozeliak quote makes it sound like it’s an incentive-laden deal." The 2019 season will mark his fifteenth season in the Majors, all of them being with the St. Louis Cardinals.

We will keep you posted as more information is released! As of now, Adam Wainwright will be a Cardinal in 2019.

UPDATE October 12: According to Derrick Goold of the St. Louis Post Dispatch, the contract with Waino is for one year at "an undisclosed low base salary, but two sources described how his new contract is rich in incentives". Goold also wrote that Wainwright will prepare for a starters role to start the 2019 season, but his contract is written to assure "he’ll be rewarded regardless of his role — which could be starter or reliever".
