Brady Heslip made nine 3-pointers and finished with 27 points Saturday to lift Baylor to an 80-63 victory over Colorado in the South Regional.
Heslip, a transfer from Boston College who grew up in Canada, helped break open a tight game with a pair of 3-pointers that were part of a 14-0 run and gave the third-seeded Bears (29-7) a 75-60 lead.
Baylor made the regional finals for the second time in three years under coach Scott Drew. The Bears will play the winner of Sunday's game between Xavier and Lehigh.
Pierre Jackson had 13 points and 10 assists for Baylor.
Freshman Askia Booker had 15 points for 11th-seeded Colorado (24-12), which saw its winning streak in the Pac-12 and NCAA tournament end at five.
