About These Closing Odds
Every price on this page is a book's own last quote strictly before Washington Nationals and St. Louis Cardinals 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. 20 books priced this game. The tables list the books you can bet; an offshore book shows when you turn it on in your books, and Pinnacle appears only as the reference on the chart. 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.
