BOSTON -- The bullpen day continues to evolve for the Rays, and one of the factors about slating a group of relievers to start a given day deals with monitoring the recovery of the pitchers.
After all, the group of relievers for the bullpen days are all former starters, save for Andrew Kittredge. They are familiar with making their start and not pitching again until they've had four days' rest.
"I think that's what we were trying to discover in Spring Training," Ryan Yarbrough said.
