On Tuesday, Moreno allowed a home run to Mike Moustakas in the 12th inning to take the loss as the Rays fell, 7-6. The 29-year-old pitched in four games over two stints with the Yankees in 2015. He was 0-0 with a 1.10 ERA in 11 appearances for the Bulls, including five saves in five opportunities. He had 17 strikeouts in 16 1/3 innings with just three walks.
"Diego's a guy who we really liked during Spring Training," Rays manager Kevin Cash said. "Showed some pitchability, obviously had a big fastball, and he's done a nice job since he got to Durham, so we're excited to have him up here."
Moreno will become the sixth non-roster invite to Spring Training to appear for the Rays this season, joining right-hander Tommy Hunter, Marks, outfielder Shane Peterson, catcher Jesus Sucre, and first baseman Rickie Weeks Jr.
"As far as Austin Pruitt goes, kind of a unique month," Cash said. "Did a lot of things to help us win some games and did some things that you could tell that he's still young and adapting to a new role.
"So I think it's more just to give him the opportunity to reset and get down there, get into a good rhythm, get to where he's feeling good about himself again. We know for us to be good, Austin Pruitt's got to play a factor or a pretty big factor in our bullpen."
Pruitt went 3-1 with a 7.52 ERA in 12 appearances including one start.
Cash said Pruitt will continue to be used in the role he served with the Rays.
"Longer relief, pitching in important innings, but giving him those two- and three-inning outings," Cash said.
Marks appeared in one game in relief for the Rays, allowing a run on two hits in 1 1/3 innings, with a walk and a strikeout. He had a 4.60 ERA in nine games with Durham this season. The Dodgers assigned Marks to Triple-A Oklahoma City.
