Dallas Comegys' 21 points led De Paul to an 81-72 upset of sixth-ranked St. John's in Rosemont, Ill., yesterday, keeping alive De Paul's hopes for an NCAA tournament bid.

His three-point play starting the second half provided a 41-31 lead.

"I made the statement before the game: this team was capable of getting into the NCAAs and going all the way," the losing coach, Lou Carnesecca, said. "I've seen it before. Villanova last year, North Carolina State a couple of years ago. If De Paul gets in and plays the way they did today, they have the chance to go all the way. It would be real easy for me to come in here and say we didn't have a good game but I'm not going to do that . . . They are a sleeping giant."
