Dugger joined the major-league club as the 27th man for a doubleheader in mid-April, but he'll now rejoin the bullpen after left-hander Nick Margevicius (shoulder) was placed on the 10-day injured list Monday. Dugger made four appearances (one start) for Miami last year and posted a 12.66 ERA and 2.25 WHIP in 10.2 innings.
