In the 2025 chapter of Major League Baseball's (MLB's) inter-league rivalry, American League (AL) teams bested their National League (NL) rivals 373 wins to 362 (50.75%) after including the NL winning the World Series + All-Star match.
The AL East led the way with a 55.5% winning record. The AL champion Blue Jays led the way with a 60% record against the NL even after dropping 4 of 7 to Los Dodgers in the World Series. No AL East squad had a losing inter-league record. The AL West finished at 51%. The AL Central's 46% record against the NL held the AL back. I will predict a Blue Jay win in the World Series based on the AL's superior record this year. I was 2 outs away from being right.
After 14 consecutive AL triumphs from 2004 through 2017, the NL won the inter-league contest for 5 of 7 seasons starting with 2018 through 2024.
The "brain gap" between AL and NL team managements shrank over the years thanks to the brain drain of smarty-pants and smarty-skirt executives who started with AL squads before crossing over to manage NL teams.
The AL's remaining claim to superiority is winning 10 of the past 12 All-Star contests, 22 of the last 27 to reach a decision and 28 of 36.
Bettors at polymarket.com gave the Toronto Blue Jays only a 32% chance of winning the World Series before the series started. I was one of the happy few picking Toronto over Los Dodgers. After decades of AL superiority in the World Series, the NL has won 5 of the last 7 with Los Dodgers winning 3 of the last 5. Over the last 2 decades from 2006-2025, the NL is ahead 12-8. From 1983 through 2005, the AL won 15 of 22 World Series championships.
