The White Sox added another potential closer to their bullpen by signing former Royals reliever Kelvin Herrera to a two-year, $18 million deal.
Herrera has a 2.82 career ERA, including a 2.75 ERA with the Royals from 2011-18. He posted a 1.05 ERA in 27 outings in 2018 before being dealt to the Nationals in June. He struggled in 21 outings for the Nats and was lost for the final month after suffering a torn Lisfranc ligament in his left foot while fielding a grounder.
Before the foot injury Herrera was disabled by a shoulder injury, but the Sox consider him a low-risk signing.
