Left-hander Chris Sale and the Boston Red Sox are working toward a long-term contract extension, league sources confirmed to ESPN's Jeff Passan.
A deal is not done but is trending that way, and the expectation is that it will get finished.
A deal, if completed, is likely to be in the five-year, $150 million range, league sources told Passan.
The Boston Globe first reported that the sides are getting close to a deal.
Sale is entering the last year of his current contract. He will earn $15 million in the final season of the five-year contract he signed with the Chicago White Sox before the 2013 season.
