2016 college baseball season preview

Last year, I introduced my open-source college baseball database (which I’ve recently updated), and showed a few example applications. I looked at win probabilities, how the new flatter seams helped increase offense, the stolen base breakeven point, and the value of bunting (honest).

But this time, I want to use someone else’s data. Chris Long (now with the Detroit Tigers) has his own collection of useful college baseball tools on his GitHub. Let’s use them to generate a season preview.

Combining Technologies to Measure Swing Development

As hitters develop, their mechanics evolve over time into a swing that both shares many commonalities with other players and is unique to their own game. But tracking a player’s progress on that journey to a consistent swing has always been tricky. Scouting and video analysis can give players a sense of how repeatable their mechanics are, but these are expensive, time-consuming, and limited to players at the highest level, whom we would expect to already have the most consistent mechanics.

Enter technology. Technological developments, including inertial bat sensors and camera-based ball tracking systems, should make it possible to develop a quantitative measure of consistency readily available to a wider range of players, with a wider range of abilities. This will allow young hitters to better measure their progress while also giving scouts and coaches a tool to judge prospective players.

In this article, we look for a way to quantify that relationship between consistency and hitter quality. We measured over 1,500 individual swings from 25 hitters, ranging in age from Little Leaguers to NCAA Division 1 players. We also collected different kinds of swings from each hitter, having each player hit off a tee and a pitching machine, with the goal of hitting first for power and later for contact.
