SEATTLE — The Seattle Mariners enter October as the statistical favorite to win the 2025 World Series, but fans eager to watch the run from T-Mobile Park may need deep pockets.

Game 1 of the American League Division Series is set for Oct. 4 in Seattle. Tickets sold out within minutes, leaving resale markets as the only option. SeatGeek, the Mariners’ official fan-to-fan ticket partner, listed the cheapest seats Saturday at $379 before fees.

Only the first three ALDS home games are available on resale platforms. The team has not announced plans for ticket sales beyond that round. Some season-ticket holders told KING 5 they have been quoted as much as $250 for upper-level seats. The Mariners did not immediately respond to questions about enforcement of physical scalping near the ballpark.
