Finding numbers like that isn't that hard. Alexander Smit as a 17 year old in rookie ball: 38 ip, 1.18era 40k. At 19, he struck out 140 in 95 innings between rookie and A ball. Gaby Hernandez put up similar numbers - 52ip, 1.03era, 64k at 18 in rookie and A ball. At 19, he dominated low A and was promoted to A+. Neither guy ever made the majors. And I wasn't hunting for them, I just randomly looked at GCL pitching leaders from 2003 and then 2004. Tons of guys have dominated that level. Did you read the link in my post? It's a good explanation for the different level of pitchers. And pitchers can play above their ranking. Radke was a #3 who had multiple ace level seasons. I really like Gonsalves, I'd rank him ahead of Kepler and think he's the Twins breakout guy this year. But his ceiling is a #3 and it's not crazy to like Kepler more. That's all I'm trying to say.
