The longest winning streak to open a season would be Howard College in 2009. The team won 57 consecutive games before losing in the playoffs. The team ended up winning the 2009 JUCO World Series with a record of 63-1. This is of course a JUCO team and this is beats any other record held by any other division (NCAA D1, D2, D3, NAIA)
