At various points of the 2018 season, St. Louis’ Matt Carpenter was the best and worst hitter in all of Major League Baseball. In his first 35 games last season, Carpenter slashed .140/.286/.272, but the next 79 games were a complete switch. In those 79 games, spanning from mid-May to mid-August, Carpenter slashed .332/.433/.721 with 30 home runs. The veteran infielder played in 145 or more games for the fifth time in the past six years, and his 36 home runs and .257 batting average restored some faith after an underwhelming 2017 campaign. Well, compared to years past that is. While Carpenter maintained his plate discipline traits that has made him an on-base machine over the recent years, the spike in power production and slugging percentage is directly correlated to Carpenter’s quality of contact.

Carpenter’s barrel rate increased exponentially, as did his hard hit percentage. See for yourself in the images below, via Baseball Savant.

Much like previous years,...
