As much as some people are quite right to decry the lack of success during nearly five decades of Seattle Mariners baseball, you can still point to them being one of the few consistent contenders in recent years. Dating back to and including 2021, they are one of only four teams to total 85-plus regular season wins each year, and this has to count for something.
Among the keys to this ongoing consistency has been the overall success of the bullpen, highlighted by ranking in the top 10 for lowest ERA between 2021-25. However, some cracks did begin to appear during this past season, with their rankings of 13th in WHIP and 16th in opposing team batting average being the poorest during the aforementioned time period.
