Whitley failed to make his scheduled start Friday at Double-A Corpus Christi due to right lat discomfort, Jake Kaplan of The Athletic Houston reports.

EDGE Analysis

Whitley returned from the disabled list Aug. 15 after missing time with a mild oblique strain, so he's dealt with his share of injuries in 2018. It's uncertain if he'll require another trip to the disabled list, but he'll be considered day-to-day moving forward.
