Cubs optioned RHPs Ethan Roberts and Gavin Hollowell to Triple-A Iowa.
Roberts, 28, did everything in his power to earn a spot in the Cubs’ bullpen this spring, posting a 1.50 ERA, 0.83 WHIP and a 4/2 K/BB ratio over six innings in six Cactus League appearances. He was simply facing an uphill battle against a crowded bullpen mix. He should be one of the first options at Triple-A Iowa that gets a shot with the big league club.
