The percentage of MLB players born outside the 50 U.S. states fell to 26.1% on opening day, the lowest since 2002. This represents a drop of 23 players from 2023's total of 270. Japan led the increase with 14 players, its highest since 2010. The Dominican Republic remained the top foreign-born nation with 93 players, down from 100 last year. Venezuela and Cuba also saw decreases, while Canada matched its highest total since 2013.

Team rosters showed variation in international representation. Atlanta and San Diego each had 15 foreign-born players, the highest among all teams. Houston, which led for five straight years, dropped to 15 players. The Braves' roster included players from eight different nations and territories. The commissioner's office reported totals of 780 active players, 162 on the injured list, and six on the restricted list.

This shift reflects changing international recruitment patterns, with fewer players from traditional markets like the Dominican Republic and Cuba, while Japan's presence grew significantly.
