From gurus to grainy video, new information age dawns for MLB sluggers

The number of tools to help players today really is amazing

While wary of oversimplifying what can be an extremely complex process, Tewksbary stresses three elements: Swing plane, depth of swing, and path of swing. A batter’s goal: A launch angle of 10 to 15 degrees, which he believes is ideal for making hard contact and elevating the ball.

With the advent of Statcast, major leaguers are able to easily track exit velocity and launch angle, providing immediate validation.

Some of Tewksbary’s concepts, however, run head-on into what many hitters are taught for years: To swing down at the ball, to stay short to the ball, and in some cases to leave untapped power on the table.

“It means that everything you think you know about hitting might not be true,” says Tewksbary. “It’s hard to be open minded.”

Cooperstown Confidential: The tale of Charley Lau – The Hardball Times

I believe Charlie Lau was the first coach to come out with a video. I bought it and must have watched it 50 times. You can check it out on youtube.com.

Optimizing the Swing, Part Deux: Paying Homage to Teddy Ballgame – The Hardball Times

So what’s a poor batter to do. It depends on what the batter is trying to do. If getting on base is the primary goal, then swinging level would appear to the best strategy. You’ll still hit a lot of home runs if the bat speed is high and the aim is good. Indeed that is exactly the approach advocated by Ted Williams, as written in his classic book The Science of Hitting. Someone who hit 521 career home run with a 0.482 lifetime on-base percentage must surely know whereof he speaks.

But to get the highest home run probability requires swinging with a larger attack angle, keeping in mind that you will fail often if the swing is mis-timed. A possible compromise is to pick some intermediate attack angle. For example, an attack angle of 120 reduces the home run probability by about 35 percent but also reduces the four-inch timing error to be about 0.4 inches. Moreover, such an attack angle is actually “level” for a typical curveball, which has a larger descent angle than a fastball.

There may well be other possible strategies, but my goal in this article is not to analyze these in detail. Rather, it is to set up a framework for doing such an analysis. While the development of the framework is still a work in progress, hopefully some useful initial steps have been taken.

It worked for Egghead Jr.
