Active Franchise Won-Loss Records by Date

The wonderful Red Sox blog “Over the Monster” noted early this past week that the Sox were somehow 0-13 in their last 13 games played on August 15.  They blamed it on uber-Sox fan Ben Affleck, as he celebrates a birthday on that day, and Boston’s 13-game “August 15” losing streak syncs up with the release of his movie “Good Will Hunting” back in 1997.

That got the VORG wondering if certain franchises have had better or worse performances on specific dates during each season.  After much parsing and manipulation of Retrosheet game logs from 1901-2011, some interesting factoids emerge:

  • Here are the best and worst winning percentages for each individual date of all seasons from 1901-2011.  If two teams are tied, and have different numbers of games played, the team with the higher number of games is listed:
