Roby was scratched from his scheduled spring start Monday due to back tightness, Katie Woo of The Athletic reports.

Any spring injuries are concerning, but it doesn't appear to be a serious issue since Roby is still in consideration to start later in the week. The 22-year-old righty is one of the organization's top prospects and could make his big-league debut sometime in 2024 with a strong showing in the minors.
