Rivalry matchups to watch
Circle the Seattle Mariners vs Athletics dates first. Rivalry nights inside MLB carry a sustained 40-70% premium over a comparable regular-season game, and the secondary market for those tickets typically thins out 3-5 days before first pitch/puck-drop/tip-off. OnlineSeats posts rivalry-specific landing pages so you can price-shop each matchup independently.
Where to sit
Buying Seattle Mariners tickets on OnlineSeats? A few quick notes on T-Mobile Park: the lower bowl behind the dugouts tends to price below center-court/sideline seats for the same row height, and the upper-deck corners are reliably the best per-dollar views in the building. Sections near the home clubhouse hold their price late because they fill last — if you're flexible, those are your late-drop candidates.
