Free-agent reliever Kelvin Herrera and the Chicago White Sox agreed on a two-year, $18 million contract that includes a vesting option for a third season, league sources familiar with the deal told ESPN.
The two-time All-Star, who was part of the dominant Kansas City Royals bullpens that led them to back-to-back World Series, could serve as closer for the White Sox upon his return from surgery to repair a torn Lisfranc ligament in his left foot. The 28-year-old has 60 career saves, including three with the Washington Nationals, to whom he was traded in the middle of last season.
