WACO, Texas — Terry Maston scored a career-high 23 points and Baylor ended a four-game losing streak with an 81-67 victory over Iowa State on Saturday night.

The lead changed hands eight times before the Bears went on a 15-0 run over a 2:12 span early in the second half. Baylor had three 3-point plays during the spurt, including one that resulted in a five-point trip after Iowa State coach Steve Prohm was hit with a technical foul.

“We wanted to come out and you want to get the crowd going, and we wanted to get some momentum,” Baylor coach Scott Drew said. “We were able to get some separation and get the crowd into the game. That really helps, especially with the zone and different things like that, because now they’re trying to score quicker and it’s harder to score quicker against (the zone).”

Baylor (13-10, 3-7 Big 12 Conference) led 51-38 at that point and the Cyclones never got closer than eight the rest of the way.

“When we went into halftime they told us to be very aggressive and take the ball to the basket,” said Maston, who was 9-of-11 shooting. “I know I was shooting a couple of fadeaway jumpers, and they told me to get in there and basically force my will into the paint and get easy buckets. So that’s what I did, and it ended up working out great.”

Manu Lecomte added 14 points for the Bears, who won despite shooting 2 for 14 from 3-point range. Baylor made up for that with a 43-35 edge in rebounds and 52-28 in points in the paint. The Bears shot 62 percent in the second half and 50 percent for the game.

Jo Lual-Acuil Jr. added 10 points and 14 rebounds for Baylor.

Donovan Jackson had 15 points to lead Iowa State (12-10, 3-7). Cameron Lard and Lindell Wigginton scored 14 points apiece. All of Wigginton’s came in the first half, and he led the Cyclones with eight assists.

“From the first play of the second half, they get a layup to start the second half on just a drive,” Prohm said. “It was drive, drive, drive, and then it was post feed, post feed, post feed. Then we got sped up on offense, but also, too, we got the ball at the middle of the paint, 10-12 feet at times. You’ve got to make those plays, and we collapsed defensively.”

Iowa State was 9 for 20 from 3-point range (45 percent), but shot 34 percent overall.

The Cyclones fell to 0-5 on the road in the Big 12, thanks in large part to inconsistency. Jackson only had two points in the first half before finding his shot in the second, while Wigginton was 0 for 7 after halftime.
