Mid-Season Evaluations for MLB Teams
As June arrives, we gain better insight into the identities of various teams and the changes they’ve undergone since last season.
For several franchises, the conclusion is straightforward: they are performing better, as indicated by their records.
However, the term “better” holds different meanings for each team. With a lengthy season still ahead, maintaining success over the next four months is not assured.
Given this context, let’s assess the seven teams that have shown the most significant improvements in winning percentage since last year, examining their key advancements and the challenges they still face as the season progresses.
1. Detroit Tigers: +.125
2024 record: 86-76 (.531)
2025 record: 40-21 (.656)
Notable Improvement: After a surprising late-season push to the postseason in 2024, the Tigers’ pitching has continued to excel in 2025. The team currently boasts the American League’s best record, potentially leading to a franchise-record 106 wins, largely due to improved offensive performance despite retaining much of last year’s roster.
Question Ahead: Can their unexpected batting success continue? Several returning players have significantly improved their performance compared to 2024, raising concerns about the sustainability of this growth.
