AI Summary grounded in real data · zero hallucination

Our model projects the Seattle Mariners as the pick with a 70% win probability. The primary drivers supporting this selection are '팀 평균자책(ERA)' and '팀 WHIP', which highlight Seattle's pitching advantage, while '최근 10경기 폼' and '피타고리안 기대승률' act as the main swing risks. The edge against the market is uncalculated, and we honestly acknowledge that our model does not beat the market over the long term.
