VERMILLION, S.D. (AP) -- Trey Norris's free throw with 1 second left lifted South Dakota over Nebraska-Omaha 87-86 on Thursday.
Omaha was led by CJ Carter's 19, while Mike Rostampour added 18 points and 11 rebounds.
South Dakota led by 10 early in the first, but Omaha came right back and trailed by just three at intermission.
A 7-0 run put USD up nine with 6:31 left, but Steffensmeier's 3s inside 33 seconds evened things before Norris' winning free throw.
