Nick Johnson kept Arizona's unblemished record going for another game, hitting a go-ahead 3-pointer with 51 seconds remaining and two free throws with 5.8 seconds left as Arizona survived for a 60-57 victory Wednesday night for its school-record 21st straight win.
Johnson finished with 16 points, five rebounds and four assists and T.J. McConnell added 11 points, eight rebounds and four assists for Arizona (21-0, 8-0 Pac-12), off to the program's best start in conference play in more than a decade.
Dwight Powell and Josh Huestis each scored 13 points for Stanford (13-7, 4-4), which outshot Arizona 38 percent to 36 percent.
