Raleigh, N.C. ? Stephen Curry looked tired. His soft, feathery shot was clanging off the rim. The slender, baby-faced sophomore seemed to be just another in a long line of stars bottled up by Georgetown’s ferocious defense.

Davidson’s run was certainly over. A good season was coming to a fitting end against one of college basketball’s elite programs.

Then, as quick as Curry can get off a turnaround three-pointer, the Wildcats staged a comeback.

Curry scored 25 of his 30 points in the second half, and little Davidson rallied from a 17-point second-half deficit to stun No. 2 seed Georgetown, 74-70, on Sunday, sending the Wildcats to an improbable spot in the round of 16.

Davidson (28-6), which hadn’t won an NCAA Tournament game in 39 years before Friday, will face No. 3 seed Wisconsin in the Midwest Regional in Detroit.

“I’m numb right now,” coach Bob McKillop said.

So is Georgetown (28-6), which was shooting 71 percent from the field early in the second half, had forced Curry to miss 10 of his first 12 shots and was in total command in its quest to make the Final Four for the second straight year.

But despite 14 points from Jessie Sapp, 12 from Jonathan Wallace and 63 percent shooting, Georgetown was undone by 20 turnovers – and Curry’s brilliance.

The son of former NBA sharpshooter Dell Curry and the player the big schools didn’t want took over, fueled by a partisan crowd just 160 miles from campus.

Curry scored 30 of his 40 points in the second half of Davidson’s comeback victory over Gonzaga in the first round, and he put together a fitting encore against the Hoyas. Only this time he did it against the nation’s stingiest defense. Georgetown came in allowing only 57.6 points per game and 37 percent shooting.

Abrams gave Texas a 74-69 lead, but the Longhorns weren’t quite safe yet. Miami’s Raymond Hicks made a three-pointer, and D.J. Augustin then shot an air ball on his first of two free throws with 1.8 seconds to play. Augustin made the second, though, to preserve the victory.
