Left-hander Enny Romero will be recalled prior to Saturday's game.
Given the fragile nature of the Rays pitching staff heading into Saturday's game, another pitcher was needed to bolster the bullpen, and perhaps the starting staff, depending on the diagnosis of Jake Odorizzi's left-side injury.
"I definitely don't want to take away from what Andrew did tonight," Cash said. "That definitely helped us win the ballgame. Probably the reason we won the ballgame. Save a lot of guys in the bullpen that didn't need to pitch. Needed the day off and he provided that."
Bellatti was credited with the win to move to 2-0 on the season, while lowering his ERA to 1.80 in four appearances during his two stints with the team this season.
