BLACKSBURG — For the first time since the 1980s, a Curry was king of the Cassell on Thursday night.

Seth Curry scored 22 points to help the Blue Devils cruise past the Hokies 88-56 at Cassell Coliseum.

The senior guard had struggled in his previous two games at Cassell, where his father, Dell, starred in basketball for Tech from 1982-86 and where his mother, Sonya, played volleyball for Tech. Dell Curry’s name, picture and retired number (30) hang from the Cassell rafters.

But this time, Seth Curry rose to the occasion.

In the first half, he scored 19 points and made five 3-pointers to help the sixth-ranked Blue Devils (23-3, 10-3 ACC) build a 48-28 halftime lead.

The last-place Hokies (11-15, 2-11), playing in a prime-time showcase on ESPN, lost their ninth straight game.

Curry’s parents looked on from the second row behind the Duke bench. Dell Curry, a former NBA standout who is the second-leading scorer in Tech history, wore Tech sneakers. Sonya Curry, a Radford High School graduate who was an All-Metro Conference volleyball player for the Hokies, wore a Duke sweatshirt.

In Duke’s loss at Tech two years ago, Curry was 0 of 2 from the field before fouling out. In Duke’s win at Tech last year, Curry had 11 points but was just 2 of 7 from the field.

On Thursday, Curry sank two 3-pointers in an 11-0 Duke run that gave the Blue Devils the lead for good at 11-4.

Duke entered the game leading the ACC in 3-pointers (7.6 made per game) and 3-point field-goal percentage (40.8 percent).

The Hokies had hoped to contain Duke’s 3-point shooters, but that didn’t happen. Duke made 10 of its first 12 3-point attempts and finished 12 of 17 (70.6 percent) from 3-point range. The 12 3-pointer tied Duke’s season high.

Duke made six of its first seven 3-point attempts for a 22-12 lead with 9:01 left in the first half. Curry, who made the All-ACC third team last season, had three of those 3-pointers.

Curry’s fourth 3-pointer, and Duke’s seventh overall, extended the lead to 37-17 with 4:04 left in the half. That bucket gave Curry 16 points.

Curry’s fifth and final 3-pointer extended the cushion to 46-26 with 1:01 to go in the half. But Curry was whistled for a technical foul for jawing with Jarell Eddie.

Duke shot 60 percent from the field in the half, including 8 of 9 from 3-point range. Tech shot 38.5 percent from the field in the half, including 0 of 7 from 3-point range.

The game featured two of the prime contenders for ACC player of the year — Virginia Tech point guard Erick Green, the nation’s scoring leader, and Duke forward Mason Plumlee.

Green scored 22 points. Plumlee had 13 points and 12 rebounds.

It was Tech’s most lopsided ACC loss of the season. It was Tech’s most lopsided loss to Duke since a 100-65 loss at Cameron Indoor Stadium in January 2005.

Duke shot 53.6 percent from the field. Tech shot 43.1 percent, including 1 of 16 from 3-point range.

It was the eight time this season Tech allowed at least 10 3-pointers in a game. Tech has lost seven of those games.

Curry finished 6 of 14 from the field in the game, including 5 of 6 from 3-point range.

Freshman Rasheed Sulaimon had 17 points for the Blue Devils, who beat Tech for the fifth straight time. Josh Hairston added 11 points.

C.J. Barksdale had 14 points for Tech, with Cadarian Raines adding 10 points.

The Blue Devils, in second place in the ACC standings, led 68-38 with 10:16 to go.

Hokies coach James Johnson tinkered with his lineup. Jarell Eddie, who had to watch walk-on Will Johnston start in his place the past two games, regained his starting job Thursday. Marquis Rankin started in place of struggling guard Robert Brown.

Eddie finished 2 of 9 from the field.
