Poppen was claimed off waivers from Arizona by the Padres on Friday.
Poppen recorded a 4.40 ERA and 1.36 WHIP through 28.2 innings in 2022 -- all career bests for the 28-year-old reliever. However, his improved ERA and WHIP was met by a career-low 6.91 K/9, which significantly hinders his fantasy value.
