Pitching strategy: Understanding balls and strikes

• Pitchers should regularly throw their fastball for strikes 60-70 percent of the time, curveballs for strikes 55-60 percent of the time, and changeups for strikes 55-60 percent of the time.
• Batters who walk with zero outs score anywhere from 40-60 percent of the time.
• A good pitcher’s strikeout-to-walk ratio should be 3-1 in college, 2-1 in high school.
