Rookie catcher Adam Moore, who began the season sharing time with Rob Johnson behind the plate, has now replaced Johnson on the Seattle Mariners 25-man roster.
Moore was brought up from Tacoma today, and Johnson - batting .191 - was optioned to the Rainiers. Both will be in their respective uniforms today.
Moore, 26, played only 19 games and batted .193 before landing on the disabled list, then being assigned to Tacoma, where he's been playing regularly since June. In 36 AAA games, Moore batted .321.
Johnson, 28, has had a tough season after undergoing surgeries on each hip last winter, struggling at and behind the plate.
Moore will likely catch the majority of games the final two months of 2010, with veteran reserve Josh Bard spelling him. Though considered the Mariners catcher of the future, Moore has played just 25 major league games.
The team needs to learn what it has in Moore, and the audition begins today.
