In baseball, hitting mechanics studies the biomechanical motion that governs the swing of a baseball player. The goal of biomechanics in hitting during baseball training is to study and improve upon the physics involved in hitting. This includes optimizing a player's swing for either maximizing their "bat speed" or time for plate coverage.
PECOTA, an acronym for Player Empirical Comparison and Optimization Test Algorithm, [1] is a sabermetric system for forecasting Major League Baseball player performance. The word is a backronym based on the name of journeyman major league player Bill Pecota, who, with a lifetime batting average of .249, is perhaps representative of the typical PECOTA entry.

The reason for the difference in the effect of a cricket ball seam and a baseball seam are two-fold: 1) The baseball seam has a more complicated pattern that mostly prohibits not having a seam on one side of the ball and 2) The baseball seam is shaped more like a ramp than a series of small bumps, as in the case of a cricket ball.
Bill James, who coined the term "sabermetrics". Sabermetrics (originally SABRmetrics) is the original or blanket term for sports analytics in the US, the empirical analysis of baseball, especially the development of advanced metrics based on baseball statistics that measure in-game activity.
