Off-Season Bullpens

When throwing your bullpens this off-season, start with your 4seam fastball. Strt with locating down the middle, splitting the plate in half. Learn to attack the middle of the plate, down in the zone and don't be happy with less than 7/10 located where you want. After establishing that you can locate down the middle, down in the zone then move to glove side and do the same before eventually working on your off speed pitches. Get it done...
