Corbin Carroll holds a commanding lead in the 2026 MLB triples race with 17, well ahead of Jake McCarthy at 13 and the rest of the field at nine or fewer, according to season-long leaderboards updated through late September. The Arizona Diamondbacks outfielder’s speed, aggressive baserunning, and repeated opportunities in the top of the lineup have produced consistent three-baggers across spacious parks, building on his prior league-leading totals from 2023 through 2025. With the regular season nearing its conclusion, the remaining schedule offers minimal realistic chance for challengers to close the gap on the rarest extra-base hit. Official final regular-season statistics will determine the market outcome.
