TAYLORSVILLE -- Know your role.
With the Lakers' top three scorers failing to reach double digits, someone needed to fill the void.
Post players Abby Toller and Sam Filiaga combined for 22 points on 10-of-11 shooting in Bonneville's 50-31 state 4-A tournament runaway over the Golden Eagles at Salt Lake Community College.
The two-time defending Region 5 champion Lakers knew they had a size advantage over Maple Mountain for Tuesday's first-round game in Bruin Arena.
"They were undersized and we have tall posts," said Bonneville junior Abby Toller, who tossed in a team-high 12 points. She was 5 of 5 from the floor with four rebounds, one steal, a deflection, a block and only one turnover in 20 minutes and 10 seconds of playing time.
"Sam is strong and knows how to post up," the 17-year-old Toller said. "She beats me up in practice."
Filiaga, a 6-foot-1 freshman, had a career-high 10 points on 5-of-6 shooting with five boards and two blocks in 14 minutes.
"We took advantage of our opportunities inside when it was open," Toller said. "We were more post oriented in the second half than the first half."
The Lakers (22-0 overall), one of the state's three remaining undefeated high school girls basketball teams, tangle with Hillcrest in Thursday's quarterfinals.
"This was good preparation for us the rest of the week. We'll focus on the next game, whoever it is," Toller said. "We don't let the rankings bother us. We want to show people what kind of team we are."
Bonneville came in allowing a 4-A low 35.9 points per game.
"Our defense was pretty solid, but not our best effort," Toller said. "They do a lot of moving on offense and we did a good job with help defense.
"Offense is not my main thing," she said. "If I have an open shot, I'll take it. But if somebody has a better shot, I'll give it to them. My role is post defense -- I'm not a big, giant post -- and rebounding. I feel like I've played well when we keep them low scoring."
The Lakers shot 46.7 percent (21 of 45), were 17.6 percent (3 of 17) from 3-point range and outrebounded Maple Mountain 28-25.
"At the start of the season, we didn't say we wanted to be 21-0 going into the state tournament," Toller said. "We wanted to win region, get the top seed and then win state.
"Losing last year (a 31-25 quarterfinal-round setback to eventual state 4-A champion Timpanogos, where Bonneville shot a frosty 17.5 percent) is big motivation for us. We're not going to let that happen again," she said. "I feel like we have something to prove. We're playing angry because we want it so bad and not have an ending like last year."
Fresno State signee Emilie Volk went 4 of 11 from the floor for nine points with five rebounds, five assists, three steals, two deflections and two turnovers for the Lakers, who committed 11 turnovers with 17 assists, 10 steals, 10 deflections and four blocks.
Point guard Cortney Porter had three points on 1-of-7 shooting with two boards, seven assists, two steals, three deflections and one turnover.
"When somebody has an off-day, somebody else steps up," Porter said. "Our whole focus has been about defense. We could have played better defense in the second half. We just let them have some easy shots.
"It's always defense with us and getting better on defense," she said. "If we focus and keep playing our game, we can win three more games."
Aleksa Gappmayer scored a game-high 14 points for the Golden Eagles (14-8), who had their five-game winning streak snapped and were 9-4 in their last 13.
Maple Mountain -- limited to a season-low point total -- shot 23.5 percent (8 of 34), including 0.8 percent (1 of 13) from deep, with 22 turnovers.
* Clearfield 50, murray 40: In their first state tournament appearance in three years, the Falcons are also in the quarterfinal round for the first time since 2010.
Behind sophomore Bailey Douglas' career-high 23 points, Clearfield (12-10) clipped the Spartans to advance to Thursday's quarterfinals versus undefeated Springville (22-0), last year's 4-A runner-up.
No other player scored more than six points for the Falcons, who are 8-5 in their last 13 games.
