Pirates closer Jason Grilli is off the disabled list after missing the past month with a strained oblique muscle.
Grilli saved 33 games last season and another four games this year before going on the disabled list, but it’s possible the Pirates will ease him back into the bullpen mix in a low-leverage role because of how well Mark Melancon has fared filling in at closer.
Melancon has eight saves with a 2.05 ERA and 15/5 K/BB ratio in 22 innings this season after making the All-Star team last year on the way to posting a 1.39 ERA in 71 innings.
A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.
Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.
Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
