Senzatela was optioned to Double-A Hartford on Friday.
Senzatela, one of the Rockies' most promising prospects, fared well in his lone outing in big league camp this spring, striking out four batters and facing seven batters in two innings of work. He'll head to minor league camp to get a bigger workload and stretch out into a starter. Senzatela figures to start the year in Hartford's rotation after spending last season at High-A.
