Methodology
Every regular season meeting since 2016 comes from the Bet Legend game database with its final score, closing moneylines, closing 1.5 run line and closing total, and each game is checked against ESPN's official final score; postseason meetings are not included. Moneyline units risk 1 unit at the close: a win at -150 pays +0.67u, a win at +130 pays +1.30u. Over and under compare total runs with the closing total, and an exact match is a push. A "clear favorite" is a game where the two closing moneylines differ. These are market results, not BetLegend picks.
