It’s a fairly quick turnaround for the 28-year-old Morin, who was designated for assignment on Tuesday after the Twins returned first baseman Eddie Rosario and outfielder C.J. Cron to the active roster. In 23 appearances for Minnesota, the righty registered a 3.18 ERA, 0.8 BB/9, and 4.4 SO/9 through 22 2/3 innings, a brief but promising improvement over the rough patch he weathered with the Mariners in 2018.
As the Phillies intend to move Morin to the 40-man roster this weekend, they’ll transfer fellow right-hander Seranthony Domínguez to the 60-day injured list in order to clear a spot for the new reliever. Domínguez, 24, suffered a UCL tear in his right elbow last month and is still working his way back to the mound — though there’s speculation that he may undergo Tommy John surgery at some point in the near future.
