Morton will pitch in a minor-league game on the back fields rather than starting Saturday's Grapefruit League matchup against the Yankees, Justin Toscano of The Atlanta Journal-Constitution reports.

Morton was scheduled to make his final Grapefruit League start Saturday, but he'll pitch in a different setting due to the threat of inclement weather. Saturday's throwing session should serve as the final tune-up before Morton starts Atlanta's second game of the regular season against Cincinnati on April 8.
