Dequesha McClanahan scored a season-high 28 points and Winthrop rolled to a 78-46 Big South Conference victory over Longwood Thursday night at the Winthrop Coliseum.

In a game that was delayed 16 minutes by a power failure in the second half, Winthrop (17-10, 12-4) won its second straight contest and remains tied for second place in the conference. The Eagles also avenged a Jan. 5 road loss to the Lancers (9-17, 6-9) who have lost eight in a row.

In one of its most dominating performances of the season, Winthrop came out firing on all cylinders in the first half to take a commanding 44-16 lead as the Eagles connected on 60 percent from the field (18-30). Winthrop’s hot shooting, combined with a frigid performance by the Lancers, led to the 28-point halftime lead.

The Eagles were without the services of Diana Choibekova, the league’s top 3-point shooter, who missed her second straight game with an ankle sprain. But it didn’t matter as Winthrop outscored Longwood 40-6 inside.

The Lancers missed their first 17 shots, and by the time Erin Neal made Longwood’s first field goal on a lay-up with 9:18 left in the period, Winthrop led 23-7. Longwood closed the half shooting just 16 percent on 5 of 31 field goals.

Winthrop’s first half onslaught was fueled by freshman guard Aliyah Kilpatrick and McClanahan. Kilpatrick scored 13 points in the opening period and finished the game with 14 while McClanahan had 12 of her 28 in the first half.

“What people don’t realize is that Dequesha most of the time was trying to beat two defenders,” said Winthrop coach Kevin Cook. “They put a lot of pressure on her and she handled it like a champion. She is just thinking the game so very well, and she was pressed to play the entire 40 minutes because we had no one else to put in.”

The only low moment for Winthrop in the first half came with 2:16 left when sophomore guard Samiya Wright fell hard to the floor after being fouled and had to leave the game with a wrist injury.

Winthrop hosts Radford at 1 p.m. Saturday.
