Four unbelievable minutes. Two gargantuan free throws.

Freshman Kim English came off the bench to "pinch shoot" for injured J.T. Tiller and made two free throws with 5.5 seconds left Sunday to give Missouri the go-ahead points in an 83-79 victory over Marquette in the NCAA tournament.

It was quite an encore for English, who had an out-of-body 4 1/2-minute shooting spree in the first half, scoring 15 points and helping third-seeded Mizzou (30-6) turn a six-point deficit into a 16-point lead.

English was on the bench for most of the second half, watching sixth-seeded Marquette chip away at the lead and eventually go ahead.

But when Tiller fell hard and hurt his right wrist after being fouled with the score tied at 79, coach Mike Anderson took advantage of the college rule that allows teams to substitute for an injured free-throw shooter.

He chose English, who made both.

"I'm so happy that he had faith in me to get up there and knock them down," English said. "I think anybody on the bench would've knocked them down, actually."

After the English free throws, Marquette's Lazar Hayward stepped over the baseline on the ensuing inbounds pass, and the Golden Eagles (25-10) were forced to foul. Leo Lyons made two more free throws to ice the game and Missouri moved onto the West Regional semifinals to play Memphis.

It ruined a wonderful effort from Marquette senior Jerel McNeal, who matched his career high with 30 points, and Wesley Matthews, who scored 24.

It also brought lusty boos from the Marquette fans and others in the crowd, especially when they saw Tiller re-enter the game a second later to help the Tigers run out the clock.

What they may not have known is that Tiller was a 76 percent free-throw shooter coming into the tournament while English, icing on the bench for most of the second half, shot only 65 percent.

"I knew, right when I looked at him, if coach chose him he was going to knock 'em down," teammate Matt Lawrence said. "I've never seen a freshman with so much confidence."

He was equally impressive in the first half.

During six extremely well-spent minutes, English came one point short of his career high. He went 6-for-8 from the floor, including 3-for-4 from 3-point range, added a rebound.

Then he came back for 1 second _ literally _ and won the game.

He turned Boise _ just maybe _ into his own private Idaho and erased a terrible memory of this place for Missouri fans. Remember UCLA guard Tyus Edney's famous full-court dash and buzzer-beating layup _ the one that sparked the Bruins to the 1995 championship? That came against Missouri. Here in Boise.

"I guess it's a new day," English said.

Missouri's usual stars weren't bad, either.

DeMarre Carroll finished with 15 points and Lyons led the Tigers with 18, including a nifty spin under the basket for a three-point play that gave Missouri a 79-78 lead with 48.7 seconds left after they'd trailed by four.

McNeal came back to make one of two free throws to tie the game and set up the wacky finish.

Nearly lost in the commotion was the return of Marquette's Dominic James, who made an unexpected comeback less than a month after a broken foot was supposed to have shut down his season. Largely considered Marquette's best player, he got plenty of playing time but didn't make a difference.

He played 17 minutes but didn't take a shot and wasn't on the floor at the end.

The game certainly brought flashbacks for Marquette, which trailed by 17 to Villanova in the second round of the Big East tournament, came all the way back but ended up losing by one.

And for Missouri _ well, it must be good to know it has another reliable player to depend on now that it's one of the final 16.

Marquette fans, meanwhile, will have a bad taste in their mouths for a while.

Not everyone was convinced Hayward stepped over the line on the inbounds pass.

"I thought what we had designed would give us a fairly good chance," Marquette coach Buzz Williams said of the play after the Golden Eagles had fallen behind by two. "But they said Lazar stepped over the line. I didn't have the perspective."

There was also some confusion at the end, when the refs had to go to the replay to see if the clock had run out when the ball went out after Marquette's final desperation heave.

Tiller's quick return to the game also brought boos, though that was within the rules. He only had to come out until the next whistle.

"J.T. better knock down these free throws, then I see him" coming out, English said when asked what he was thinking. "But J.T. is one of the toughest guys on our team. He definitely would've taken those shots" if he could have.
