The White Sox have designated right-hander Tayron Guerrero for assignment, the team announced. The move makes room for outfielder Luis Robert, whom the White Sox signed to a long-term contract Thursday.
This ends a very short run with the White Sox for the 28-year-old Guerrero, whom the White Sox claimed off waivers from the Marlins on Dec. 6. Although Guerrero’s average fastball approaches 100 mph, he hasn’t been effective in the majors since he debuted in 2016 with the Padres. Through 106 innings, including 46 in 2019, Guerrero has only managed a 5.77 ERA/5.08 FIP with 9.42 K/9 and 5.69 BB/9.
