The Blues signed 26-year-old center Peter Mueller to a one-year, two-way contract yesterday. Mueller was selected eighth overall by the Arizona Coyotes in 2006 and scored 54 points in his rookie season. However a career plagued by injuries led to him playing for three different NHL teams in six seasons and most recently a season with the Swiss club, the Kloten Flyers. Mueller recorded 46 points in 49 games for the Flyers last season.
