In an article from the Los Angeles Times, data suggests the Astros did not cheat to beat the Dodgers in the 2017 World Series. Or if they did, it didn't help them.
Here's a snippet:
"This won’t be a popular conclusion in Dodgertown, but new analyses of the Astros’ 2017 season by baseball’s corps of unofficial statisticians — “sabermetricians,” to the sport — indicate that the Astros didn’t gain anything from their cheating; in fact, it may have hurt them.
The most comprehensive analysis, and the most explicit finding, comes from Robert Arthur, who posts at the statistical websiteBaseball Prospectus.
Arthur is a data scientist who also has worked at the statistics site FiveThirtyEight.com, where he established that a change in the baseballs used in the major leaguescontributed to a jump in home run rates, a finding later confirmed byMajor League Baseball’s own investigation.
Arthur’s analysis resembles those of some other experts who have found eithera very modest gainfrom the cheating orone that’s virtually impossible to quantify in the real world."
