Notes

Comments

2/19/25

One of the day’s loudest rounds of BP came from Diego Herrera (Huntley, 2026). The right-handed hitter delivered a heavy barrel through the zone with intent to lift to his pull-side and up the middle, reaching up to 101 mph for his EV while averaging 93 mph, also working on the sweet spot 87.5% of the time per TrackMan. Herrera then showed well during defense, where he attacked the baseball and fielded in-stride off his front foot, showing some feel for the position.
