The Baltimore Orioles defeated the Houston Astros 8-7 on Sunday, one of the biggest upsets in Major League Baseball over the past 15 years.

The Orioles were listed as high as +420 underdogs.

The Astros were one of the largest single-game favorites ever. They closed as -460 favorites at Caesars Sportsbook but could be found as high as -550 favorites at Station Casinos' sportsbooks in Nevada.

Station Casino sportsbook director Chuck Esposito said his shop took minimal straight bets on the Astros-Orioles game, but added that Houston was a popular pick on parlay bets.
