Zion Williamson and Duke are advancing to the Sweet 16 by the skin of their teeth.
The freshman phenom and presumptive No. 1 overall pick in this year's NBA Draft scored 32 points and grabbed 13 rebounds to lead the No. 1 overall seed Blue Devils, who needed a comeback in the waning seconds of the game to escape with a 77-76 win over nine-seed UCF.
Fellow freshman R.J. Barrett -- also a consensus top five pick -- poured in 16 points. Tacko Fall, the 7-foot-6 big man for the Knights, went for 15 points and six rebounds.
