The introduction of the ABS pitch challenge system in Major League Baseball has resulted in a significant increase in player height restrictions, with 225 of the 430 hitters listed on Opening Day rosters listed at shorter heights compared to the previous year's rankings. Six players saw their official heights drop by three inches, 48 by two inches, and 171 by one inch, while 45 hitters gained one inch and two hitters gained two inches in MLB's effort to ensure the most accurate strike zones possible. The players now listed at 5'11" lost an average of 0.82 inches of height during the changeover, the most of any height, according to Sam Blum of The Athletic. Several prominent MLB players, including Toronto Blue Jays first baseman Vladimir Guerrero Jr., Los Angeles Angels outfielder Mike Trout, Philadelphia Phillies first baseman Bryce Harper, Seattle Mariners catcher Cal Raleigh, and New York Mets outfielder Juan Soto and shortstop Francisco Lindor, saw their heights decrease.
