I thought this was really cool: Baseball-Reference has added game logs and splits dating back to 1957. Awesomeness. So what sort of fun stuff do we find?
From 1957 to 1967, Whitey Ford pitched 2161.1 innings. He allowed 20 stolen bases. Twenty. In eleven seasons. Versus 32 caught stealings. And 32 pickoffs. That's nuts. He had four separate seasons ('58, '59, '61 & '64) of at least 200 IP and no stolen bases.
How insane is that? Nolan Ryan allowed at least 20 stolen bases every single season from 1971 to 1992.
As a percentage of runners on first base, 2.5% of baserunners attempted to steal off Ford. Compare that to 17.4% versus Ryan. Runners simply didn't challenge Ford.
