The Dodgers optioned Jackson to their minor-league camp Monday, Eric Stephen of SBNation.com reports.
Jackson will likely open the season at Double-A Tulsa. During his last minor-league season in 2019, he split time between High-A Rancho Cucamonga and Low-A Great Lakes, logging a 3.06 ERA and a 141:57 K:BB in 114.2 innings across the two stops.
