Alvarado secured his first save of the year and allowed a hit and a walk while striking out one in a scoreless ninth inning Friday against Houston.
Alvarado ultimately managed to slam the door, but he allowed two batters to reach base before doing so. The 23-year-old finished the 2018 campaign with eight saves (against four blown saves) but should have more opportunities this year, even though the Rays haven't officially designated him as the team's closer.
