Nottingham's play was one of few bright spots for the Brewers during a 16-4 loss.
Seattle had claimed Nottingham off waivers from Milwaukee last week but then designated him for assignment. The Brewers announced Sunday that they acquired him for cash.
"We just needed to bring another catcher into the organization, and somebody with familiarity works out great," manager Craig Counsell said before Sunday's game.
Nottingham, 26, was playing in his first major league game this year. He hit .188 with four homers and 13 RBIs in 20 games last year and entered Sunday with a .203 batting average, .306 on-base percentage, five homers and 17 RBIs in 38 career games.
"He knows our group," president of baseball operations David Stearns said. "He knows our organization. It made sense to be able to bring him back and plug him right in there."
Mario Feliciano, who made his major league debut Saturday and scored the winning run in a 6-5, 11-inning victory over the Dodgers, was optioned to the Brewers' alternate training site in Appleton, Wisconsin.
