He was phenomenal. He wasn't known for pinpoint control, which made that unreal heater that much scarier.
The guy was called up to the major leagues at 17 years old! He was also the best pitcher in baseball by the time he was 21.
Its interesting you note 1946 was his best season. He had lost the previous three and half years serving in WWII. Its incredible he was able to return at such a high level after that much time away.
He's fun to listen to today, too. I love angry old timers.
