MESA, Ariz. -- The Cubs trimmed the spring roster to 49 players on Friday, assigning top prospects Adbert Alzolay, Oscar De La Cruz and Duane Underwood Jr. to Double-A Tennessee.
The three pitchers ranked No. 1, 3 and 30, respectively, on MLB Pipeline's top 30 Cubs prospects list.
Thomas Hatch, the Cubs' top Draft pick in 2016 and ranked seventh on MLB Pipeline's list, also was assigned to Minor League camp. Neither he nor Alzolay appeared in any of the Cubs' Cactus League games but that was by design.
