The White Sox owe James Shields, who posted a negative 0.2 fWAR this year, $11 million in 2018 with the Padres paying the balance of his $21 million salary and the $2 million buyout of the 2019 option.

The Red Sox owe Hanley Ramirez, who posted a negative 0.4 fWAR this year, $22 million in 2018.
However, Steamer projects 2018 WAR of 0.2 in 29 starts for Shields and 1.0 in 574 plate appearances for Ramirez.
Because that many plate appearances for Ramirez would vest the $22 million option for 2019, the Ramirez contract may well be worse.
