Kerr was optioned to Triple-A El Paso on Wednesday.
EDGE Analysis
Kerr was traded to the Padres during the offseason, and he allowed two runs on three hits and two walks while striking out five in three innings across three relief appearances during Cactus League play. The left-hander will begin the year in the minors but will likely be in the mix to make his major-league debut at some point this season.
