My son started 7 of our 9 league games his senior year in HS plus another 3 or 4 non-league games and then 2 tourney games....so 12 or 13 games as a starter at what I would average to be around 75 per game so around 1000 plus maybe a few more in relief. He probably pitched 6 or so games worth in the summer.....so total somewhere around 1500-1600. A college pitcher on a team with a 3 man weekend rotation would start 13 or 14 games per year. Assuming 85 or so on average would put him around 1200 per season.....plus whatever he throws in the summer.
