This would be a great comeback, but for me the wildest comeback for a division lead is still the 2006 season. End of July 2006 the Twins were like 9 games back from 1st place Detroit, then they just went on a tear. They had an amazing August and September, and then it all came down to the KC sweeping the Tigers in the final series while the Twins watched the final out on the metrodome jumbotron. Twins ending up winning the division the final day of the season.
