Orioles sign free agent RHP Stewart
Stewart pitched the past two seasons with the Minnesota Twins. He was 2-2 with a 6.39 ERA in nine games last season, starting twice and allowing five home runs in 25 1/3 innings.
Over this career, the 25-year-old Stewart is 4-3 with a 4.79 ERA in 17 appearances, including six starts.
To make room for Stewart on the 40-man roster, Baltimore designed right-hander Marcos Diplan for assignment.
