Whitlock agreed to a four-year extension to remain in Boston through 2026 on Sunday, with two additional club options for 2027 and 2028.

EDGE Analysis

The base of the deal will cover each of the seasons for which Whitlock is arbitration eligible, and the club options cover his first two years of free agency. Whitlock is a valuable arm out of Boston's bullpen, as he is capable of working multiple innings or in high-leverage roles. He could also shift into the starting rotation at some point, though he has yet to do so at the big-league level.
