Part 7/9:
Shifting focus, Alejandro Rosario’s trajectory has also drawn attention. Known for his lackluster college performance at the University of Miami, Rosario has undergone a transformation since turning professional. Under the Rangers’ development umbrella, his control and secondary pitch usage have markedly improved, resulting in a staggering drop in his walk rate from 11.6% in college to just 3.7% in pro ball.
Rosario's growth is particularly compelling, as he was once a highly-touted high school prospect with arm talent that outshone his results in college. Now, with a 224 ERA over two levels of competition, he stands as a testament to the Rangers' ability to nurture and develop pitching talent.
