Top 25 Baseball Stories of 2018 — No. 20: The baseballs have changed

1 Comment

We’re a few short days away from 2019 so it’s a good time to look back at the top 25 baseball stories of 2018. Some of them took place on the field, some of them off the field and some of them were more akin to tabloid drama. No matter where the story broke, however, these were the stories baseball fans were talking about most this past year.

Much has been written about the composition and performance of baseballs over the last couple of years. In 2017, Five Thirty Eight’s Rob Arthur pointed out that newer baseballs have a lower drag coefficient, which led to longer fly balls and which, in turn, likely led to the surge in home runs over the previous few seasons. In 2018 a new study emerged that, not only do the balls fly farther, but that they also can cause blisters.

Dr. Meredith Wills, an astrophysicist, took apart some baseballs and studied the composition in a study for The Athletic. She found that the seams in newer baseballs are nine percent thicker than seams used on 2014 baseballs. Wills pointed out that thicker laces make the baseball less likely to deform after contact with the bat, keeping spherical symmetry. That, Major League Baseball concluded in its own study, likely reduced the ball’s drag. Wills observes that the thicker laces could also lead to the increase in blisters on pitchers’ fingers. Many pitchers have suspected this for some time. The study shows they are right to suspect it.

Why are the balls different now? No one really knows or, at any rate, no one will admit it if they know. Major League Baseball has suggested it could be a simple manufacturing error.

Now that Major League Baseball owns Rawlings, I suppose it’s their responsibility going forward, eh?

Carlos Correa likely headed to injured list again

Per MLB.com’s Brian McTaggart, Astros manager A.J. Hinch said shortstop Carlos Correa will likely be placed on the 10-day injured list due to a back injury. Correa exited Monday’s game against the Tigers after two innings due to the back issue.

Correa, 24, missed two months between May 26 and July 26 due to a broken rib. Back issues aren’t anything new to him either, as he missed time last year with back issues as well. This season, the shortstop is batting .278/.358/.556 with 19 home runs and 56 RBI in 310 plate appearances.

Alex Bregman handled shortstop for a majority of the time Correa was out earlier this year, shifting over from third base. That could once again be the case going forward, with Yuli Gurriel taking over at the hot corner.
