Good knuckleballs always seem to give batters fits, but I can imagine it would be quite difficult to chase after a long afternoon of Bob Gibson fastballs. Schultz broke in with the Cardinals in the late 50s, spent a few years on the Cubs, and finished his career on the Cardinals in 1965. His best season came in 1964 when he posted an ERA of 1.64 and an ERA+ of 234. That's 234. Aroldis Chapman posted an ERA+ of 151 last year. Kimbrel was over 300. I was surprised that Schultz appeared in a certified autograph set, but happy to add the card.
