LUBBOCK, Texas - It's all falling apart on Oklahoma State.

Less than a month after back to back wins over No. 16 Baylor and No. 8 Kansas, OSU's season hit rock bottom on Saturday in Lubbock with a 63-62 loss to lowly Texas Tech.

The Cowboys have now lost four games in a row, including a loss at fellow bottomfeeder TCU.

Phil Forte was held scoreless for the first time all season and just the fourth time in his three-year career. OSU's sharpshooter missed all four of his shots and both of his 3-point attempts.

Le'Bryan Nash scored 19 points on 6-of-9 shooting to help pick up the slack. Nash also dished out five assists. Jeffrey Carroll also gave the Pokes a lift, although highly unexpected. The 6-foot-6 freshman drained four 3-pointers and finished a double-digit scoring total for just the fourth time all season. Carroll had played just eight total minutes in OSU's previous nine games.

Michael Cobbins recorded another double double for the Pokes with 10 points and 11 rebounds. Tyree Griffin added 10 points as he started in the place of Anthony Hickey. Hickey chipped in six points and six rebounds off the bench.

But thanks to some hot 3-point shooting, OSU's efforts were all for not. Toddrick Gotcher hit 4-of-5 from downtown while Robert Turner knocked in three of four. Tech shot a whopping 62.5 percent from deep.

OSU trailed 31-17 at the half but battled back late and even took the lead on a Carroll 3-pointer with 8:05 to go. It was back-and-forth from there as the two teams exchanged leads. Tech took a 60-56 lead with 1:06 to go, but OSU came right back. And then, with 18 seconds to play, Carroll knocked down yet another 3 and the Cowboys took a 62-60 lead.

But Devaughntah Williams answered back with his second 3-ball of the game to clinch the win and break the Cowboys' hearts.

The loss drops OSU to 17-11 overall and 7-9 in Big 12 play. The four-game skid has now dropped the Pokes into the dreaded bubble territory with the NCAA Tournament just a couple of weeks away.  Tech improves to 13-17 overall and 3-14 in the conference.

OSU can get back on track on Wednesday night against TCU.
