There’s an assumption that parity represents the ultimate success for any sports league. Fans generally dislike seeing the same elite teams dominate annually. In the NFL, this belief is cited as a reason for its consistent high ratings, despite notable players like Patrick Mahomes and Tom Brady winning seven out of the last twelve Super Bowls. Fans who value parity should appreciate the 2026 American League standings.
An Unexpected Season in the American League
As September approaches, the 2026 regular MLB season is nearing its end, with most teams having 30-32 games left. This year’s American League (AL), especially the AL West, is on course to make an embarrassing historical record. In MLB’s history, no team with a losing record has reached the postseason during a full season. However, with just over a month of games left, only four teams in the AL have winning records. Alarmingly, three of these teams are in the same division.
The American League West’s State
Not a single team in the American League West holds a winning record. The Houston Astros and Texas Rangers are tied at 65-66. The Seattle Mariners, who both bought and sold players at the trade deadline, stand at 62-69, having been outscored by 61 runs this year. They are seven games under .500 and seemingly out of postseason contention. Surprisingly, they are just three games away from both first place in their division and the third wild card spot.
The Cleveland Guardians are tied with the Rangers and hold the third wild card spot with a 65-66 record. The Toronto Blue Jays, major contenders in 2025, are 1.5 games back at 64-68. Even the Detroit Tigers, now without ace Tarik Skubal, are 3.5 games behind despite a 61-69 record. The Kansas City Royals, having won eight in a row, are only 7.5 games from a wild card, sitting at 58-74.
Parity Across the League
The Tampa Bay Rays, at 77-53, have the best record in the AL. Despite their success, the gap in winning percentages between the fourth-best team, Chicago White Sox, and the twelfth, Detroit Tigers, is merely five percentage points. Nine AL teams are on track to finish with 77-83 wins. According to Fangraphs, 11 AL teams have at least a 12% chance of playoff qualification. The Mariners, with their 62-69 record, have a 35% playoff chance. Even with a losing record, the Astros have a 16% chance for a first-round bye.
National League Differences
Meanwhile, the National League exhibits a different trend. Ten out of fifteen teams have a positive run differential. The Cardinals trail narrowly with a -2.
This situation arises partly due to AL team owners prioritizing profits over strengthening rosters. Mid-to-small market teams in the NL have committed to higher salaries, enhancing talent levels, as seen with the Arizona Diamondbacks and San Diego Padres. Even committed organizations like the Blue Jays experience disappointing seasons when stars like Vladimir Guerrero Jr. underperform.
The result may see a shift from no teams entering the playoffs with losing records to several teams doing so in one season. Such parity underscores the narrowing gaps among teams today. Despite the Dodgers’ talent pool, they have struggled against others like the Red Sox, Cubs, and Brewers. Advances in pitching strategies and data analytics have lessened the disparity between top pitchers and others. Increased focus on maximizing effort per pitch and the abundance of skilled relievers have simplified run prevention. These elements have fostered remarkable parity, proving timely as league owners consider player lockouts over competitive balance concerns.
