As a die-hard Orioles fan, I can tell you that the Orioles provide maybe the best chance for Hart to return to the bigs. The O's have a soft spot for scrappy, light-hitting, borderline-AAAA types. Consider that the team's 25-man roster currently includes one Brandon Fahey and one Luis Hernandez -- and one Freddie Bynum is on the DL.
So Bo Hart fans, rejoice! Your boy is one Brandon-Fahey-pulled-hamstring-on-a-sacrifice-bunt-attempt away from another chance.
