I saw an interview with Koufax and he said early in his career he was having trouble with his control. the advice he was given, and took, was to throw his fastball with about 85% effort, sort of like a second serve in tennis... he said after that it was night and day.. he had his control and dominated.
I do think you'd have a hard time convincing the hitters he dominated that he was throwing less than 100% .... but it was a very interesting interview.
I gotta be careful here because I don’t want to start a war, so please hear me out before ya’ll get too angry.
I’d heard that too, and had the opportunity to talk about it with a very very close personal friend of Koufax’s , who was also the Dodgers pitching coach for 12 years.
He said that although Koufax had retires before he took over the PC duties and couldn’t say for sure, what was said was probably slightly misunderstood, and he got me to understand this way.
Assuming that Koufax had his greatest success throwing his FB at 95mph, which is by all estimates on the low side, that would mean his “A” or 100% FB would have to be at least 112mph, and that’s flat out impossible. But, as he further explained, too often people think that the 85% effort translated straight across to an 85% reduction in velocity, but that wasn’t at all what was meant.
He went on to say that even in the late 30’s when he’d started his pro career, it was very common for coaches to tell pitchers to not to try too hard. What they were talking about was, when someone gets all amped up to give something “everything he’s got”, usually the result is, all the muscles get all tightened up, thus becoming less flexible, and that’s a bad thing. What ends up happening is, rather than throwing harder, many times they actually don’t throw as hard as they can.
So chances are, what was meant is, he just relaxed and didn’t try to throw the ball through the side of a battleship, and by doing that, he stayed “loose”, and was able to control the ball much better. Sure, he might have dropped from maybe 100 to 96 or 97, but that’s only a 3-4% loss which was more than made up for by what probably was a 15-20% improvement in command.
OK, now you can get mad at me!
