Spencer Dinwiddie turned in 24 points as the No. 19 Colorado Buffaloes survived a challenge from Texas Southern, 85-80, in double overtime in a non-conference battle.
Josh Scott added 18 points and 12 rebounds while Andre Roberson totaled 11 points and 12 boards for the Buffaloes (6-0), who have won the first six games in a season for the first time since 1989-90.
"To me the story of the night was Texas Southern, not the Colorado Buffaloes," Colorado head coach Tad Boyle said. "Their kids played their hearts out (and) we were fortunate to win."
Omar Strong's game-best 39 points -- aided by nine three-pointers -- wasn't enough for the Tigers (1-6), losers of four straight contests. Fred Sturdivant contributed 12 points, 11 rebounds and five blocks to a valiant, but losing effort.
"Our team put forth a lot of effort tonight and we came up short against a very talented team. I'm extremely proud of the way our guys fought out there. We have definitely given ourselves something to build on in the future," Tigers head coach Mike Davis said.
Scott rescued Colorado from a worse fate, notching this first five points of the second overtime period on a jumper and three-point play to make it 76-71. Texas Southern was forced to foul down the stretch, and the Buffs sank 5-of-6 from the line to seal the victory.
TSU was down by six with under five minutes to play in regulation, but Sturdivant's layup in the final minute forged a 59-59 deadlock and forced an extra session.
Once there, the Tigers were up 66-63 when Strong connected from long distance, but found themselves down by three after an Askia Booker triple. Lawrence- Johnson-Danner countered for the visitors and a second OT was necessary after Booker's desperation heave from long distance failed to hit the net.
Texas Southern jumped out to a 12-4 lead in the game's first five-plus minutes, and led 24-12 with under nine minutes to play in the first half on a Kyrie Sutton bucket.
Strong made two from the line and the edge ballooned to 39-26 before a Booker trey pulled Colorado within 10 at the break.
Sabatino Chen's 3-pointer capped an early second-half surge and provided a 45-42 edge for the Buffaloes, and the game seemed to be in hand after Dinwiddie's triple made it 56-50 with 6:46 to play.
Colorado has won all four meetings ... Booker ended with 15 points, six rebounds and four assists ... Dinwiddie shot 16-of-18 from the charity stripe ... Neither team was effective from the floor, with the Buffaloes and Tigers both connecting on under 40 percent of their shots.
