Struggling Mets reliever Edwin Díaz has been activated from the injured list, and New York manager Carlos Mendoza reiterated that Díaz will return to the closer role. Díaz had been sidelined since May 29 with a right shoulder impingement. Before going on the IL, he blew three consecutive save chances and four out of five opportunities. He also squandered a four-run lead in the ninth inning on May 18 at Miami and was not charged with a blown save. After missing last season with a knee injury he sustained celebrating Puerto Rico’s victory in the World Baseball Classic, Díaz is 1-1 with a 5.40 ERA and five saves in 20 appearances.
