WASHINGTON TERRACE -- Once the offense starts complementing the defense better, the Lakers can be a juggernaut.
"A win is a win," said Bonneville coach Mike Russell. "But our offensive output has been lacking all season. We need to transfer what we do in practice to game situations, and that might be mental.
"I think our offense is a mental thing, and I've been thinking of switching benches," he said. "It's not like we're a bad offensive team trying to find scoring. We have 6-7 girls who can score."
If not for Cortney Porter and Mountain Crest's dismal free-throw shooting, Bonneville would not have corralled the Mustangs 41-25 Thursday in its Region 5 opener.
Porter, a senior point guard who has signed with the U.S. Air Force Academy, scored a game-high 18 points on 8-of-15 shooting, including 1 of 2 from 3-point range.
She also had three rebounds, five assists, five steals and only two turnovers for the two-time defending league champion Lakers (8-2 overall, 1-0 league), who are undefeated at home this season.
Porter put in 11 of Bonneville's 14 third-quarter points.
"I got more aggressive and took it to the hole," she said.
The Lakers, on a three-game winning streak, led by 15 points after three quarters.
"We have to start with a better mentality," said the 18-year-old Porter. "We got off to a slow start and picked it up. The layoff had a little affect, but not a lot."
Bonneville was playing its first game since Dec. 28, 2013.
"We were really anxious to play. We had great defense; our defense stepped up," Porter said.
The Lakers limited Mountain Crest (5-4, 1-1) to a season-low point total and single-digit scoring in three of four quarters.
"Our defense got us some steals and our shots started to fall," Porter said. "We take a lot of pride in our defense. We played man-to-man and a 2-3 zone, so we can do both. It's whatever is needed to stop the other team.
"We knew we needed to pack it inside and guard their good perimeter shooters," she said.
The Mustangs shot 29.6 percent (8 of 27), including 12.5 percent (1 of 8) from beyond the arc, and got outrebounded 33-27.
Mountain Crest was 8 of 17 at the free-throw line with three assists, three steals and 23 turnovers.
"It's just the atmosphere of playing at home. We need to protect our homecourt, definitely," Porter said.
Bonneville's last home-court loss -- a 40-37 non-league overtime setback to Weber High -- was on Dec. 15, 2011.
"The girls know we have to win at home, but it's not something we overemphasize," Russell said. "Every game we come out, and offensively, we're like this. I don't know if we're too tight or too hyper.
"We have the capability of being great offensively," he said. "We're waiting for that breakout game offensively. We're really good defensively, and when our offense starts playing like we're capable of, we'll be tough to beat."
Lakers sophomore center Sam Filiaga rang up a double-double with 10 points and 11 rebounds. She was 5 of 7 from the floor with one block. Senior power forward Abby Toller struggled through an 0 of 11 shooting night, but had five boards, two assists and three steals.
Bonneville shot 34.0 percent (18 of 53) -- 22.2 percent (2 of 9) on 3-point attempts -- with nine assists, 13 steals and 12 turnovers.
"We have to take it one game at a time and work hard at practice," Porter said. "A league three-peat is one of our team goals."
* LOGAN 55, OGDEN 37: At Ogden, the Grizzlies brought a red-hot shooting attack to town and blitzed the Tigers.

Ogden was led by Allie Hyde, who had a game-high 15, while Katelyn Shaw added seven points.
Logan led 28-16 at the break.
In the other Region 5 contest, Sky View topped Box Elder 74-56 at home.
