Barrett (shoulder) is scheduled to throw an inning Tuesday during a simulated game at expended spring training, the Associated Press reports.

EDGE Analysis

Barrett was placed on the 10-day disabled list to begin the season after complaining of shoulder inflammation early in spring training, which prevented him from pitching in Cactus League games. While the fact that he's now throwing in games is a positive step, Barrett will likely require several outings to build up his arm strength and make the Diamondbacks feel comfortable about activating him. He could be back with the big club by late April or early May if he incurs no setbacks with the shoulder along the way.
