Notes

Comments

2/19/25
INF Nathan Rosalez (Huntley, 2027) had a strong all-around day and looks to be an intriguing young infielder to follow for the Red Raiders moving forward. Throughout his round, the right-handed hitter showed loose, athletic hands that work to stay on top of the baseball and keep the ball on a line or on the ground. Rosalez also impressed the staff with his actions on the infield; playing low to the ground and showing range up the middle, paired with a steady glove.
6/19/24

Rosalez proved to be an infielder to follow going forward after his performance friday morning against Brew State Academy. Rosalez showed smooth actions at shortstops with range. At the plate Rosalez showcased an athletic stance with a swing that generated power. He led the game off for GRB Rays Illinois with a hard hit single, taking the ball where it was pitched. Later in the game he sent a deep double to center field to put his team on the board. Rosalez is a name to keep an eye on in the coming years.
