Purdue won its NCAA tournament opener for the 14th straight time. The Gaels were back in the tournament for the first time since their surprising run to the round of 16 in 2010.
Johnson had 21 points for the 10th-seeded Boilermakers (22-12). Jackson scored 15 of his 18 in the second half and Hummel and Anthony Johnson finished with 10 apiece.
Purdue turned back the Gaels repeatedly in the second half before the West Coast Conference champions made one last push.
Matthew Dellavedova’s three-point play got the Gaels within 66-58 with 4 minutes to play.
After Dellavedova took a charge from D.J. Byrd, he drove the length of the floor for a layup. Hummel missed at the other end, and Jones hit a jumper to make it a four-point game with 2:41 left.
Terone Johnson badly missed a free throw, and Jones hit a baseline jumper.
Jackson’s drive to the hoop put Purdue back up 68-64 with 1:37 left. Dellavedova made a couple of free throws to pull the Gaels within two. After Hummel missed a 3, Page took a pass from Dellavedova for his only 3 of the night and a 69-68 Saint Mary’s lead.
Hummel, back in the tournament after missing the past two Purdue appearances because of ACL tears in his right knee, didn’t seem to miss a beat on the big stage. He hit an early 3, swapped some skin with Ryne Smith on the way back to play defense, and later got a friendly bounce from the rim on a baseline jumper.
But Terone Johnson, starting his eighth straight game after beginning the season on the bench, carried the Boilermakers in the first half. He shot 6 of 8 and had 15 points, almost double his season average.
He scored seven points in an 8-0 Purdue run, finishing the spurt with a layup after Byrd rebounded Jackson’s missed free throw for a 27-16 lead.
Saint Mary’s struggled for the first 20 minutes, shooting just 31 percent and missing all but one of their 15 3-point attempts. The Gaels finished at 42 percent and went 4 of 25 on 3s.
The atmosphere at CenturyLink Center was subdued early, with the crowd drained from No. 15 seed Norfolk State’s 86-84 upset of Missouri in the previous game.
During the first media timeout a group of Norfolk State players walked into arena, some still in game jerseys, and got a big cheer as they lifted their hands to raise the roof.
