Fulmer was recalled from Triple-A Charlotte on Friday.
This move makes sense with rosters expanding, as Fulmer is on the 40-man roster. However, he has a 5.79 ERA, 1.56 WHIP and 96 strikeouts in 126 innings (25 starts) at Triple-A this year, so it's not as though Fulmer has earned a promotion. He figures to take on a bullpen role over the final month.
