Jorge Montanez breaks down the last week in saves and middle relievers on the rise in the latest closer report.

Yankees closer Luke Weaver has been placed on the 15-day injured list with a strained left hamstring sustained while warming up at Dodger Stadium last weekend, an injury that moves Devin Williams back into New York’s closer’s role.

It goes without saying, but losing Weaver to the IL is a significant blow to the back of the Yankees’ bullpen. The closer — who was moved back to the ninth inning after Devin Williams’ shaky start to the year — has a 1.05 ERA with eight saves over 25 2/3 innings this season.
