Not much was expected of Cruzeiro this year. It hadn't made any impact on the Brazilian league since 2010 and was ninth last year.
Coach Marcelo Oliveira was relatively unknown, and the most notable player was a defender, Dede, who has played for Brazil for two years.
But at the halfway point in the league, Cruzeiro took the lead, then built a comfortable advantage and has been cruising ever since.
On Sunday, the team from Belo Horizonte can cap the most dominating performance in the league since it went to its current format in 2003, with every team playing each other twice. That was the year Cruzeiro achieved the first domestic treble, which included its second and last national title. But that was won with two rounds left.
If the trophy comes on Sunday with five rounds left, Cruzeiro will beat the 2007 mark set by Sao Paulo, which clinched the title with four rounds to play.
