• Reassigned to the Minor League camp were: right-handed pitchers Jonathon Crawford, Nick Howard, Nick Travieso and Stephenson; left-handed pitcher Ismael Guillon; infielder Neftali Soto; and outfielders Ryan LaMarre and Winker.
The moves leave 54 players in Reds big league camp.
Stephenson, the organization's top prospect according to MLBPipeline.com, pitched at Double-A Pensacola last season. He got a late start in camp because of some shoulder soreness, but he was able to throw live batting practice on Monday and felt fine.
Winker, the Reds' No. 2 prospect and in his first Major League camp, was 2-for-7 with two RBIs in four games this spring.
Duran, who split last season between Class A Advanced Bakersfield and Pensacola, hit a three-run walk-off homer to beat the Angels on Monday.
