After dealing with some elbow soreness in the Spring, Weiss started the 2016 season in Double-A after getting a look in big league camp. Through May, Weiss had still not made an appearance. Weiss was originally a sixth round pick by the Reds in the 2013 draft out of UCLA. Weiss has been used exclusively as a reliever by the Reds with very strong K/9 numbers to follow. He posted a 11.4 K/9 in 2014 and 12.7 between two levels in 2015. Weiss works with four pitches, including a low- to mid-90s fastball, a slider, a curve, and a changeup.
