The Nationals outrighted Barnes to Triple-A Rochester on Wednesday.
EDGE Analysis
Barnes looks as though he'll stick around in the Nationals organization after he went unclaimed off waivers upon being designated for assignment earlier this week. The right-hander was cast off the 40-man roster after turning in a 6.75 ERA and 1.50 WHIP across 13.1 innings out of the Washington bullpen this season.
