MLB halfway grades: White Sox out front in the American League, while Mariners and Blue Jays stumble

Major League Baseball is roughly halfway through its 2026 regular season, with each club having played at least 81 games by the time the schedule approaches July and the All-Star break. In its midseason review of the American League, CBS Sports delivered team-by-team “halfway grades,” treating the first half as a barometer for who looks built to contend and who is still searching for answers.

The report’s top note in the AL goes to the White Sox, which CBS framed as leading “the pack” through the opening portion of the schedule. The context matters because midseason performance often sets the internal direction for the rest of the year: teams that separate themselves early typically gain flexibility at the trade deadline, while those that fall behind begin recalibrating expectations.

CBS’s review also pointed to high-profile disappointment stories for the Mariners and the Blue Jays. In both cases, the publication described them as failing through the first half, a blunt label that indicates more than just a rough stretch. In the AL, where playoff spots are frequently decided by small gaps, an underwhelming first half can force a team to chase outcomes it cannot simply “wait out.”

The point of a grading exercise is not the letter itself, but what it represents. A team can be competitive and still receive a mediocre grade if it has failed to convert leads, solve late-game problems, or show stability in the areas it must rely on for October. Conversely, a top grade often reflects consistency across multiple phases of the season, not just isolated success.

As the All-Star break nears, the practical takeaway for AL clubs is that the second half will be treated differently. Teams that earned stronger marks can focus on maintaining what worked, tightening execution against divisional opponents, and sustaining roster health. Teams that CBS characterized as disappointing likely face more pressure to identify fixes, whether that means changes in pitching usage, lineup regularity, or broader team strategy.

There are also reasons to treat any midseason “grade” as a snapshot rather than a verdict. Baseball seasons can swing when injuries resolve, when younger players seize opportunity, or when rotation and bullpen patterns normalize. Still, a first-half grade can help explain why certain organizations will feel urgency when the calendar turns to July.

The next watch item for American League fans is whether the teams most singled out by the review improve, stabilize, or continue to drift as the season reaches its decisive middle stretch. For Chicago, the question is whether the early momentum holds steady; for Seattle and Toronto, it is whether the problems that drove the “failing” labels are fixable before the standings tighten further.

Bottom line: CBS’s halfway report paints a clear contrast across the AL, with the White Sox positioned as the early standard and the Mariners and Blue Jays placed among the major concerns. The second half will show how much of that picture reflects durable team-building versus first-half variance.
