Narveson was outrighted to Triple-A New Orleans on Monday, Joe Frisaro of MLB.com reports.
EDGE Analysis
The move was procedural in order to open a spot on the 40-man roster. Narveson's debut with the Marlins was pushed back to August after suffering a left elbow sprain in spring training, but in 15 appearances, he managed a 4.45 ERA, 1.088 WHIP, and 32:9 K:BB in 30.1 innings.
