Mets360 - A look at home runs of Pete Alonso in the COVID-19 shortened 2020 season

 


By Chris Flanders January 4, 2021

About this time last year, we were still reveling in the remarkable season that Rookie-of-the-Year Pete Alonso had, led by a remarkable barrage of 53 HR, which set a rookie record and led the major leagues. I decided to analyze each at bat leading to all 53 of Alonso’s home runs. Much to my surprise, he covered a lot of the plate, in particular the outer half, and from low to up in the zone. What looked like a hole was the inner part of the plate, although perhaps this was him being pitched away more than his inability to cover the inner half. Although the 2020 season classifies as “unusual” relative to any major-league season any of us can recall, it was still worth the effort to review the 16 home runs Alonso had in 2020.

Like last year, I watched each home run pitch multiple times in order to see the entire context of the pitch he hit out. In 2020, SNY displayed a K-zone box (much to my viewing unhappiness, but great for this work), making charting the location a lot easier. Like with my previous analysis, this article will feature a five-zone map to locate pitches (inner upper, inner lower, outer upper, outer lower, and middle middle) instead of the conventional 3×3 matrix. Factors looked at include the pitcher throwing arm, count, home v. away, NL v. AL, and inning the HR occurred. Unlike last year, pitches leading up to the home run were not considered. Part of the goal is to see what, if anything, changed from 2019 to 2020 seasons.

Comparing these two seasons is of course difficult for obvious reasons, but also because the numbers are quite imbalanced. Everyone could see the outward frustration with Alonso’s at-bats in 2020, with a tendency to chase outside, even way outside, to the point he looked like a minor leaguer. Interestingly, Alonso was on pace to have 30 or so fewer strike outs in a projected 2020 full season relative to 2019. So many of the at bats looked like he was totally lost, which magnified the agony to watch, but a strike out is a strike out. Other things were really similar, too, on an adjusted basis including games played and at bat totals.
