Where Pinnacle's line opened, and where it closed

This game was listed before Pinnacle priced it, so the number below is Pinnacle's earliest price on it rather than the first number anyone posted. It was actually posted, it is stamped with its own time, and the market may already have moved before it existed.

About these closing odds

Every price on this page is a book's own last quote strictly before Seattle Mariners and Athletics started, taken from our scan archive. A book that stopped pricing the game early still shows the number it closed at, and a book that never priced it is not listed. 19 books priced this game. Prediction market prices include trading fees wherever a fee applies, so they are directly comparable to sportsbook lines. See how we calculate this.

This page is permanent. The closing prices above do not change again, and the page keeps them at this address after the game, the season and the rematch, so it stays a citable record of what this line actually closed at.

For today's games, open the MLB board or the Line Shop.
