LUBBOCK, Texas — It was as risky a pass as Graham Harrell has ever thrown. Also the most important.

With the final seconds ticking off and Texas Tech trailing by a point, the Red Raiders' quarterback saw Michael Crabtree in double coverage and let it fly. The All-American wide receiver snagged it on the sideline, shook off a defender and ducked into the end zone with one second left.

With that stunning 28-yard touchdown, the No. 6 Red Raiders turned near-heartbreak into a wild victory, 39-33 over No. 1 Texas, last night.

Texas Tech showed it is tops in the Lone Star State — and maybe even the best team in the land.

"Play 60 minutes," Texas Tech coach Mike Leach said. "You may have a second to spare."

That's what it came down in a West Texas-style shootout that had the Longhorns (8-1, 4-1 Big 12) rally from a 19-0 deficit in the first half and from 29-13 in the third quarter to take a 33-32 lead with Vondrell McGee's 4-yard TD run with 1:29 to play.

The problem was, Texas left Harrell too much time.

Harrell drove the Red Raiders (9-0, 5-0) 62 yards to the touchdown in six plays, slinging the long pass to Crabtree, who broke the tackle of Curtis Brown, kept his balance, stayed in bounds and scooted the last few yards for a score.

Tech really just needed about 10 yards to set up a field goal for Donnie Carona, who had been benched earlier this season but kicked a 42-yarder in the fourth quarter. But Harrell took a big chance with the big throw.

If Crabtree had been tackled instead of getting in, Texas Tech might have had a hard time calling its last time out to set up a short field goal before time expired.

"On the sideline, I kind of dreamed that I would catch a pass and go in the end zone for a game-winning score. I do that, like every game, but it happened. It kind of shocked me," Crabtree said.

"All we needed was a field goal, but a touchdown's even sweeter," Harrell said. "If you're a quarterback and don't want to be in that situation, you should probably change positions."

Thousands of Texas Tech fans poured onto the field and had to be sent off while the play was under review to make sure Crabtree didn't step out of bounds. Once the fans were chased off the field and Tech kicked the extra point, the Red Raiders were penalized and forced to kick off from their own 7.

When Texas couldn't pull of a miracle kickoff return, the fans ran back on the field to celebrate the biggest win in Texas Tech history. The victory not only gave the Red Raiders command of the Big 12 South, it puts them smack in the chase for the national title, quite a leap for a program usually left behind by conference powers Texas and Oklahoma.

In fact, maybe Texas Tech shoots to the top of the rankings and the BCS standings? More likely, Alabama moves to No. 1. The question is whether the Red Raiders, on the strength of their first victory against a No. 1 team, can jump over the likes of Florida, Southern California and unbeaten Penn State today.

Just like Texas over the last month, the Red Raiders also face a daunting schedule the next three weeks. Texas Tech hosts No. 9 Oklahoma State next weekend, then has a bye week before traveling to No. 4 Oklahoma. The Red Raiders finish the regular season at home against Baylor.

"Now the biggest game in history is Oklahoma State," Leach said, "or the history of this year, anyway."

Harrell, who may have jumped ahead of Texas quarterback Colt McCoy in the Heisman Trophy race, finished with 474 yards passing and two touchdowns on 36 of 53 passing.

"Some of you guys maybe ought to add him to your Heisman list," Leach told reporters after the game. "I know how political it is."

McCoy has nothing to be ashamed of, throwing for 294 yards and two touchdowns and nearly leading his 10th career comeback in a game where he was sacked four times and had his face bloodied on a hard hit in the third quarter. He did have an interception returned for a touchdown in the third.

"They played harder than us," McCoy said. "The crowd was behind them the whole game. They never quit. They kept fighting.
