At the onset of the World Series, WhatIfSports.com's MLB simulation engine declared New York the favorite, predicting the Mets to win the title in six games. However, the Mets' odds spiraled downward following two losses in Kansas City. With the series heading to New York, we simulated the remainder of the World Series and found that Kansas City was the team to beat, with the Royals winning 71.5 percent of the time.

After their 9-3 victory in Game 3, the Mets have some positive momentum heading into tonight's Game 4 matchup. But how does the win impact each team's odds? We simulated the rest of the World Series -- from Game 4 onward -- to determine which team now has the upper hand. Check out the results:
