MLB.com's Corey Brock tells us, via Twitter, that the Padres have designated right-hander Edwin Moreno for assignment in order to make room on the 40-man roster for catcher Jose Lobaton.
The Padres were forced to create room for another catcher on the roster following injuries to both Nick Hundley and Henry Blanco.
Moreno, 28, was 1-3 for the Pads with a 4.84 ERA. He had notched 15 strikeouts through 22.1 innings to go along with 15 walks, while opposing hitters were batting .311 off of him.
Lobaton, 24, is hitting .248/.301/.360 with three home runs through 37 games at AAA this year.
