ST. LOUIS, Mo. (AP) Roman Penn scored a career-high 26 points, including 12 straight to start a game-breaking 18-0 run midway through the second half, and eighth-seeded Drake shocked Missouri Valley Conference champion Northern Iowa 77-56 in a quarterfinal game on Friday.

The Bulldogs shot 59% and led by as many as 16 before settling for a 43-33 halftime lead. The top-seeded Panthers battled back and three times Austin Phyfe pulled them within two, the last time at 50-48 with 12:36 to play.

Shortly after that, Penn went to work. It started with a pair of free throws at the 10:50 mark. He followed up with a couple of layups and a pair of 3-pointers. After teammate Liam Robbins scored inside, Penn hit another jumper and Garrett Sturtz capped the 18-0 run with a pair of free throws for a 67-48 lead with 2:28 to play.
