He’s had a bit of a bumpy start to his LA Angels career given his rough 2017 season (6.16 ERA in 57 IP) before a spring training injury to his back and kept him out all of 2018.
This is only speculation, but given Chris Rodriguez’s smooth 2016 debut in the Arizona League (1.59 ERA in 11.1 IP) and the pure power of his stuff you’d have to wonder how bad his back affected him through 2017. Regardless of this speculation the Angels excitement comes not from his performances, but his makeup and electric stuff.
Chris Rodriguez is a four pitch pitcher, sitting most comfortable with his fastball/sinking two-seamer combo while throwing in an electric slider and above-average change-up to round out his repertoire.
