12:33pm: The Reds have outrighted Allen to Triple-A Louisville, MLB.com’s Mark Sheldon tweets.
Allen never actually made a plate appearance for the Reds. They signed him to a minor-league deal in November and selected his contract on Friday, but he did not appear in a game. The 30-year-old played for the Mets’ Triple-A team in Las Vegas last season, batting .273/.350/.478. He last played in the big leagues in 2012, and he compiled a .203/.290/.375 line in parts of four seasons in the bigs.
