The Cubs are going to have yet another player make his MLB debut this season; there have already been three (Christopher Morel, Brandon Hughes and Ethan Roberts).
Swarmer, who has made nine appearances (five starts) for Triple-A Iowa with pretty good results (2.08 ERA, 0.949 WHIP), has been added to the 40-man roster and called up as the 27th man for today’s doubleheader. He’ll start Game 1 against another pitcher making his MLB debut, Ethan Small of the Brewers.
Nelson Velazquez, who was the Arizona Fall League MVP last year, has also been called up and will make his MLB debut.
