HALLSVILLE -- Senior setter Haley Boyett served 21 straight points points in Tuesday's 25-4, 25-18, 25-10 District 15-5A win against Sulphur Springs.

It was that kind of night for Hallsville, the Texas Girls Coaches Association's No. 2 team state-wide in Class 5A.

"Whenever I went back there, I just told them, 'OK guys, I'm going to 25," Boyett said. "I just stayed focused. They would give me zones, but I would just focus on getting it in and serving aggressive."

The setter's 21 straight serves broke with a 4-4 tie for a 25-4 decision. Sulphur Springs burned both of its timeouts in the frame and still could not phase Boyett.

She aced three serves, forced another three Sulphur Springs return errors, recorded five assists and scored on a kill in the run. Sulphur Springs committed another three net infractions during the spree as it got more desperate to break serve.

"Just her being able to stay focussed that long is impressive," Hallsville head coach Kayla Jackson joked in front of Boyett. "She served tough all of those points. She had to work against zones and we really worked on that.

"She has a tough serve. She does. She has a great floater that's a bullet right at you. They couldn't handle it. Then we were able to handle it when they put it in play."

Hallsville's win moved the team to 28-1 and 4-0 in league play.

Sulphur Springs didn't lay down though. The second set was tightly contested.

Hallsville faced a 12-11 deficit midway through the frame.

Laura Gray tied the second game with a kill on a Boyett assist. Savannah McAmis aced the ensuing serve and then Gray put down a great block for a 14-12 Hallsville lead.

Sulphur Springs called a timeout, but it lost six of the next eight points on mistakes. Hallsville only had one kill in the stretch.

That made the second set score 21-14. Sulphur Springs could not recover.

Hallsville opened the third set on a 16-3 run en route to an easy win.

Boyett recorded all of Hallsville's 34 assists in the match. She also finished her night with eight aces and two digs in addition to a second kill.

Allison Lawrence was Boyett's primary target. She scored 14 kills.

Erin McCallm added a team second-best nine kills.

Lexi Harvey and McAmis combined to save 17 points in the win on digs.

Hallsville will host Marshall on Friday. A win and a simultaneous loss for No. 1 Frisco Centennial (28-2) could be enough to launch the Ladycats into first place in next week's poll.

"We really have high expectations this year," Lawrence said. "We want to go to that state tournament. We're working our butts off in practice. I really think we can do it if we keep our minds set."

That goal was once abstract. A significant chunk of Hallsville's team has been playing on the varsity squad since 2012.

Hallsville now has a team capable of scoring 21 straight points.

You'd think the Ladycats would have relaxed at some point during Tuesday's big run.

"Not at all," Boyett said. "We're too competitive for that."
