Alvarado could see save chances in Tampa Bay after Alex Colome was traded to the Mariners on Friday.
The Rays have not yet named a replacement for Colome in the ninth inning, but Alvarado is the presumptive favorite to step in. He's the only other pitcher besides Colome to have recorded a save for the Rays this season, plus he throws hard and misses bats. Alvarado, a left-hander, has also been mostly split-neutral, holding opposite-handed hitters to a .167/.271/.225 batting line so far this year (with lefties batting .161/.257/.161).
