Rosario has yet to make it to full-season ball after four years as a pro, including three in the United States, but he'll get there in 2012 after making impressive strides last season. After his fastball worked at 90-93 mph in 2010, it jumped to 93-97 and exploded on hitters last year. One scout saw him throw five consecutive 97-mph heaters in one game. Rosario has good life to go with his velocity, and he also has improved his ability to command his fastball. He has a chance to develop a plus slider, though his is presently more notable for its mid-80s velocity than its bite. It lacks consistency and gets slurvy at times. His changeup is even more rudimentary, and some scouts wonder if he'll develop a deep enough repertoire to remain a starter in the long run. His lack of size also may not be conducive to the durability needed to stay in the rotation, though he generates his velocity with arm speed and not effort. Rosario has the ceiling of a No. 3 starter or a set-up man, but it will take a few more years before the Cubs know exactly what they have in him.
