Lee Cummard scored 17 points, including eight in the final two minutes, to lead BYU to a 54-49 comeback victory over Air Force and a share of the Mountain West Conference championship.
Cummard made six free throws in the final 1:04 to give the Cougars (24-6, 12-4 Mountain West) the lead and send the Falcons to a school-record 17th straight loss.
Andrew Henke led Air Force (9-20, 0-16) with 14 points and freshman Trevor Noonan scored a career-high 11. The Falcons forced the Cougars into their worst scoring and shooting night of the season. BYU shot 34 percent from the field, including 3-for-22 behind the 3-point line.
A season-high 22 turnovers ruined the Falcons' bid for an upset.
BYU has now won three straight conference championships, the first time that's happened in 75 years. The Cougars won three consecutive Rocky Mountain Conference titles from 1932-34.
