11:05 AM PT -- TMZ Sports spoke with J.J. on Wednesday and he told us he actually called his shot ... saying he told teammates at halftime he was "pretty sure" he was going to get 100!!!
J.J. also told us his younger bro didn't believe that he was getting buckets at will ... but said the Timberwolves stud went CRAZY when he FaceTimed him after the game!!
Move over, Wilt ... there's a new member of the 100-point game club -- NBA star Jarrett Culver's older brother, J.J. Culver!!
The 6'5" senior out of Wayland Baptist scored the absurd figure in his NAIA game against Southwestern Adventist in Plainview, Texas on Tuesday ... logging 100 points in just 38 minutes.
The stat line is wild ... J.J. took 62 shots, including 33 3-pointers, and added 27 free throw attempts. He also had 5 steals, 2 blocks, nine rebounds and an assist!
The numbers were so crazy, his older brother -- who was the No. 6 overall pick of the Minnesota Timberwolves in last year's NBA draft -- said of the guard, "jj you a legend brother."
As for the game itself, J.J.'s squad obviously won ... beating the hell out of Southwestern Adventist, 124-60.
"Definitely a dream come true," J.J. said of the night. "I put in a lot of work for this. I love playing basketball and thanks everyone for the support."
J.J. -- who's just the second-ever NAIA player to hit the 100-point mark -- added, "Couldn’t have done it without my Coaches, Teammates, and Family."
Humble guy too!
