In his first season in Brazil, Day gained visibility and became known for being extremely dangerous from the three-point line. His great performances earned him a spot in the NBB All-Star Game, held in Franca, where he played for a team composed of foreign players, called NBB Mundo (NBB World), against a team composed entirely of Brazilian players. Day started the game on the bench, but when he entered the court, his story began to be written. With a rare performance from the three-point line, Day hit an unbelievable 12 three-pointers and scored an incredible 50 points. NBB World won the match 115–99 and Day was named the MVP of the game. During the season, Robert Day, assisted by Robby Collum and Valtinho, led the team to the quarterfinals of the championship, being eliminated by Brasília of Alex Garcia, Guilherme Giovannoni and Nezinho dos Santos.
