Phelps was placed on the 10-day disabled list on Friday with right elbow posterior impingement.

EDGE Analysis

He could still technically return this season, but an elbow injury like this with a month left in the season makes it seem like a bit of a long shot. Nick Vincent, Emilio Pagan and James Pazos will be charged with getting the ball to Edwin Diaz in the ninth inning while Phelps is sidelined.
