It’s a truth universally acknowledged that relievers are going to reliever (hat tip to our old friend JT Morgan).
It’s very very rare to find a reliever who can be effective nearly every outing across a season (let alone multiple seasons!) So for a while Garrett Cleavinger is lights out, then he has a week of stinkitude, and then he finds his stride.
And now we have Shawn Armstrong, who has mostly been pretty reliably decent for the Rays...
