The White Sox haven't revealed whether Slater suffered the injury while warming up before first pitch, or if his oblique had been bothering him during his prior four Cactus League games. Regardless, Slater is likely to be held out of action for at least a few days,

"We all know what each other goes through and what this job entails," pitcher Penn Murfee said. "It’s a group effort, pushing each other and having a good time doing it.”

Austin Slater became the latest Chicago White Sox outfielder slowed by an injury after he was scratched from Monday’s lineup because of a strained left oblique. Slater was originally penciled in to play left field Monday against the Athletics at Camelback Ranch.
