Colorado Rockies catching prospect Wilin Rosario fixed his struggles in the Arizona Fall League by instituting a toe-tap trigger mechanism in his swing, reports Jack Etkin of Inside the Rockies. The new swing helped Rosario, the Rockies #3 prospect according to Baseball America, turn his fall season around.
The 20-year old Dominican native batted .266/.297/.404 in High-A this season. He has shown the ability to hit for power in the past, but he must refine his plate discipline.
