The Seattle Mariners have been something of a thorn in the side of the Detroit Tigers. The Mariners, of course, were the club that vanquished the Tigers in a heartbreaking winner-take-all 15-inning marathon, but their torment of the Tigers goes so much deeper.
Both clubs entered 2025 on the verge of becoming legitimate contenders, but they took divergent paths as the season progressed. Detroit saw its massive AL Central lead evaporate before its very eyes, while Seattle came roaring back to steal the AL West from the Houston Astros, ensuring the collapse of the perennial playoff powerhouse.
