LUBBOCK, Texas – Texas Tech's Davide Morettiscored 20 points after going 12-for-12 at the free-throw line, Jarrett Culver recorded his third double-double of the season and Tariq Owens provided 16 points and six rebounds in an 84-80 overtime win by the No. 11 Red Raiders in a game that was tied at 71 after regulation on Wednesday at the United Supermarkets Arena.

The Red Raiders (22-5, 11-4 Big 12) extended their winning streak to six games with the victory, improved to 16-1 at home this season and are now tied with Kansas State (11-4 Big 12) atop the conference standings going into this weekend's game at TCU. Tech committed only seven turnovers and owned a 44-34 rebounding advantage, but the Cowboys (10-18, 3-12 Big 12) finished the game making 17 3-pointers including a last-second one by Lindy Waters to force overtime.

"I think we have shown a lot of balance and we have different guys stepping up," Texas Tech coach Chris Beardsaid. "We continue to be a good defensive team. Oklahoma State really stretched us with that 3-point shot. A lot of respect for Oklahoma State, a team that has zero quit in them. I've said consistently I think they're going to be a factor in the championship in Kansas City. Tonight, our guys found a way to play, and found a way to win when the other team was playing lights out."

Owens would lead the Red Raiders with five points in overtime with a dunk on the first possession, a layup of an offensive rebound for a two-point lead with 3:23 remaining and then a free throw for a three-point lead a minute later. Matt Mooney scored four of his six points in overtime, making his first overtime layup with 1:13 remaining and then his next with 34 seconds to play. Tech led by two after Mooney's layup before Moretti iced the game by making four straight free throws in the final 20 seconds to secure the game.

Moretti finished the game a career-high 12 free throws and is now shooting 78 of 84 (92.9 percent) at the line this season. He recorded a conference-high also despite only going 3-for-4 from the field including being 2-for-2 on 3-pointers. He hit his second 3-pointer with 2:26 left in regulation to give the Red Raiders a four-point lead and would also make four free throws in the final 20 seconds to give the team a 71-68 lead before Waters extended the game five minutes. Culver recorded his fifth career double-double by going for 19 points and 10 rebounds, while Odiase had eight rebounds and eight points in the win. Texas Tech finished the game shooting 41.8 percent from the field, but was only 3-for-19 on 3-pointers a game after matching a program-best with 16 in the win over Kansas last Saturday. Mooney also added six assists for the second straight game and sixth time this season. 

The Red Raiders had eight players score in the game, including getting seven from Deshawn Corprew who finished with seven points and three rebounds while Brandone Francis and Kyler Edwards both had four. 

Texas Tech led 37-27 at halftime with Culver leading the team with nine points after starting the game on a 5-0 scoring run of his own, while Owens had nine points and three rebounds. Odiase had six points and four rebounds and Corprew had four for the Red Raiders who were shooting 40 percent from the field. The Cowboys were down only 10 after knocking down seven 3-pointers to overcome a 24-14 rebounding advantage by the Red Raiders who were only 2-for-10 from beyond the arc.

Culver, who also had five rebounds in the first half, started the game on a 5-0 run with a jumper and 3-pointer. The Red Raiders would go on a 6-0 run to take a 13-7 lead on a Corprew layup and had another 8-0 run on a Culver jumper for a 33-22 lead with 3:36 remaining in the half. The lead was at 13 on an Owens putback where Culver had three offensive rebounds on his own misses before Owens grabbed the fourth offensive board of the possession and scored. The Red Raiders had only three turnovers in the half, was 7-for7 from the free-throw line and had eight assists on 14 field goals.

Texas Tech swept the season series against the Cowboys after also earning a 78-50 win on Feb. 13 in Stillwater. It was the first sweep of OSU since 2016 and only the third time in program history.

Texas Tech has matched a program-best with 11 conference wins in a season. 

The Red Raiders improved to 51-48 all-time in overtime games with the win, including going to 4-2 in OT under Beard. It was the first overtime game of the season and first since a 73-71 win over Texas last season. 

Texas Tech has led by double-digits at halftime for five straight game.

Texas Tech will return to action against TCU at 3 p.m. on Saturday in Fort Worth before hosting Texas at 8 p.m. on ESPN's Big Monday for the home finale at the United Supermarkets Arena.
