The White Sox took a calculated gamble when they signed the right-hander to a one-year, $1.75 million deal last winter with a $4 million option for next season. Paulino made $1.5 million in 2014 despite making just four starts with an 11.29 ERA.
Paulino was coming off elbow and shoulder procedures and had not pitched since 2012 when the White Sox brought him aboard as a starting pitcher candidate.
The club elected to buy out the rest of his deal for $250,000.
The White Sox’s 40-man roster is at 37 players.
