"Do Dramatic Wins Matter?"

From the Retrosheet research page, a study by Brian Connolly checks whether dramatic ninth inning victories translate into a psychological boost that means more wins in the future.

The answer: no.

But there was one anomaly: teams that came from one run behind today turned out to have won yesterday's game at a .580 rate (versus only .508 on the season). No idea why that would be the case.
