Kariya, who missed all but 11 games a season ago after having surgery on both hips, played for the first time since Nov. 5, 2008. Johnson, the No. 1 pick of 2006, also saw his first action for the Blues since missing all of last season with a knee injury.
Unlike the Blues, Minnesota brought mostly minor league players.
Kariya got the Blues on the board 4:25 into the opening period, beating Wild goalie Anton Khudobin using defenseman Jamie Fraser as a screen. Porter scored 29 seconds later off an assist from Armstrong, who is in camp with the Blues on a pro tryout.
Chris Mason stopped all 10 shots he faced for the Blues before being replaced by St. Louis native Ben Bishop midway through the second period.
