Schreiber earned the save Saturday, allowing one walk and striking out one batter over a scoreless 1.1 innings in a 5-1 win over the Rays.
Schreiber put the kibosh on a Tampa Bay rally in the eighth inning, coming on with two runners on base and the potential tying run on deck. It was his fifth save, four of which have been converted by getting more than three outs. The Red Sox may have found something in the 28-year-old right-handed reliever, who has a 2.24 ERA and 0.88 WHIP over 52.1 innings. He's not expected to take over the closer's role, but Schreiber's in the mix along with Garrett Whitlock, who will likely get most of the opportunities.
