BROOKINGS – Mike Daum posted another 20-20 double-double and first-place South Dakota State used a 20-2 second-half spurt to pull away from North Dakota, winning 80-55 Saturday evening at Frost Arena.

The Jackrabbits (20-6, 10-1), winners of nine in a row, hold a 1 1/2-game lead over Omaha (14-9, 8-2) in the Summit League standings.

“I thought it was, obviously, a tough first half for us shooting the basketball – 0-for-15 from 3; the way we shoot it, it’s not going to happen too often,” said SDSU coach T.J. Otzelberger. “We talked a lot at halftime about how defense and guarding and getting deflections and steals was going go get us going on that other end.

“I thought that second half, defensively, was about as well as we’ve played in a half on that end of the floor. It allowed us to open up that game, so I’m proud of our guys for how they came out of the locker room at halftime. They had great energy and effort.”

The home team did, in fact, miss all 15 of its attempts from long range in the first 20 minutes. However, it still led 33-32.

“I just thought our shot selection wasn’t where it normally is in the first half,” noted Daum, who finished with 29 points on 10-of-19 shooting to go with 20 rebounds. “We really weren’t aggressive driving down hill and then getting those kickout open 3s like we normally get. I think we were just settling for passing the ball around, not really spacing correctly and I think that just kind of led to us not getting the shots we wanted.”

Daum quickly ended the 3-point drought with a trey 20 seconds into the second half.

Tied at 38 moments later, SDSU rattled off the big run to take control.

It started with Alex Arians’ traditional three-point play. Skyler Flatten’s steal led to a big slam on the other end. After Tevin King buried a jumper in the paint, Daum converted a pair of free throws to make it 47-38 with 15:26 remaining.

The Fighting Hawks’ lone points of the run came soon thereafter. Flatten had an and-one of his own and David Jenkins canned back-to-back 3s. Daum’s post bucket put SDSU up 58-40 with 13:06 showing on the clock.

SDSU shot 50 percent (30-of-60) for the game – 27-of-35 (77.1 percent) on 2-pointers and 3-of-25 (12 percent) on 3s.

South Dakota State plays at Omaha on Thursday at 7 p.m. and at North Dakota State on Saturday at 4 p.m.

Notes: Daum had 34 points and a career-high 21 rebounds during a 78-74 win in Grand Forks, N.D., on Jan. 16.
