Seattle Mariners Home Favorite Betting Trend

The Mariners' historically poor performance as home favorites stems from a fundamental disconnect between market perception and actual team strength during their extended playoff drought era. Seattle consistently found itself overvalued by oddsmakers when playing at T-Mobile Park, largely due to casual betting public's tendency to back the home team regardless of underlying metrics. The franchise's inability to develop consistent offensive production, particularly in clutch situations, meant they frequently failed to cover spreads that assumed competent run production against weaker opponents. Seattle's pitching staff, while occasionally solid, rarely dominated enough to compensate for offensive deficiencies when laying runs. The team's struggles were amplified in day games and weekend series when recreational betting volume peaked, inflating their lines beyond reasonable value. Their poor situational hitting with runners in scoring position became particularly costly when expected to win by multiple runs, turning close victories into failed covers. The psychological weight of being favored seemed to expose Seattle's lack of killer instinct, with players pressing in situations where they were expected to dominate. This trend becomes most dangerous for bettors when Seattle faces struggling pitchers or teams on lengthy road trips, as the market overadjusts for apparent mismatches that the Mariners historically failed to exploit.
