BOSTON -- Mariners manager Scott Servais said Edwin Diaz being the everyday closer again is "not set in stone," but acknowledged the 23-year-old is the best fit for the club in that role and will likely handle most of the ninth-inning duties after getting the save in Thursday's 4-2 win over the Nationals.
Diaz was shifted out of the closer spot after walking four batters in the ninth inning May 15 against the A's. He threw two scoreless innings in a setup role against the White Sox last Friday and a scoreless seventh with two walks in Wednesday's 5-1 loss to the Nationals before moving back to the ninth to pick up his eighth save in Thursday's victory in D.
