STILLWATER, Oklahoma (Ticker) -- Andre Emmett scored 28 points and Kasib Powell added 19 as Texas Tech rallied from an 11-point halftime deficit to post a 62-57 victory over Big 12 Conference rival and 17th-ranked Oklahoma State.
Emmett collected 20 points in the second half as the Red Raiders (16-8, 6-7 Big 12) won for just the fifth time in 16 meetings with the Cowboys since the formation of the conference in 1996.
"I thought that Andre Emmett played the best all-around game of basketball that I have seen in the last two years," Red Raiders coach Bob Knight said. "In every phase, he was a factor."
Emmett also contributed nine rebounds, four assists and six steals.
Texas Tech improved to 2-5 in conference road play and recorded a much-needed quality road win in an attempt to bolster its case for an NCAA Tournament at-large berth.
Melvin Sanders led Oklahoma State with 17 points, but the Cowboys (20-6, 9-4) lost for the third time in four games.
"We softened up and we got stagnant (in the second half)," Cowboys coach Eddie Sutton said. "It is pretty hard to win when your top three scorers (Sanders, Tony Allen and Victor Williams) go 14-for-40."
The Red Raiders were trailing by 12 just over three minutes into the second half when they embarked on a 16-3 run.
Emmett forced a turnover and hit the ensuing jumper to ignite the surge, but Powell scored the next 14 points for Texas Tech.
Powell, the Red Raiders' second-leading scorer this season, hit a jumper and converted a pair of free throws to pull Texas Tech within 38-29.
The 6-7 senior converted a three-point play and made a jumper with 14:17 remaining to close the deficit to four.
"In the first half, I was thinking too much about things," Powell said. "In the second half, I just relaxed and went out there and played like I'm capable of playing."
After making 1-of-2 from the line, Powell hit consecutive jumpers to cap the outburst and give the Red Raiders a 39-38 advantage with 12:21 left. That marked their first lead since midway through the opening half.
"I think that this was a game, as was the game Saturday (against Texas A&M), where we made some plays that we had to make," Knight said.
Sanders made a layup with just over eight minutes to play to open a 50-47 cushion for Oklahoma State.
But Texas Tech put together a 9-2 run over the next five minutes. Emmett had six points during the span, sparking the burst with an assist on Will Chavis' layup and capping the scoring with a free throw to make it 56-52 with 3:08 remaining. The Red Raiders never trailed thereafter.
