TAYLORSVILLE -- Box Elder became the first team to score against the state 4-A runner-up Skyhawks in seven games.
But the two-time defending Region 5 champion Bees couldn't finish off Salem Hills in the round of four undefeated teams Tuesday at the wind-swept Valley Complex.
Deadlocked 2-all after seven innings, Box Elder played the percentages in the eighth and it backfired.
Loading the bases with no outs to get a force-out anywhere, the Skyhawks' Kirtlyn Bohling answered with a walk-off grand slam over the center-field fence in a 6-2 victory.
Salem Hills extended its winning streak to 13, while allowing just four runs over that span.
"This is disappointing. We were looking for ground balls to the left side and outs at the plate," said Box Elder coach Mandy Hodgson. "We were playing the percentages to try and get a force-out.
"We need to be able to step up at the big dance with the big crowds," she said. "We're in a comfort zone at home, and we need to play like that in a different environment."
Molly Horne, a Salt Lake Community College commit who missed Thursday's shutout victory over Olympus with a strained muscle in her lower back and hasn't practiced, went 3-for-3 with two doubles.
Horne's two-out RBI double over the left fielder's head tied the score 2-2 in the sixth inning.
"I think we tighten up for some reason when we play here," Hodgson said. "The girls need to play in the same comfort zone we have on our home field and just relax."
The Bees (24-2 overall), who have dropped their last two against Salem Hills, face Region 5 rival Roy High in an elimination game today. Box Elder has beaten the Royals six consecutive times over the last two seasons.
"We can do it and stay in this thing," Hodgson said. "We have great pitching and a great defense. They have to understand hard work got them here.
"It's not how hard you get hit, it's how hard you get up and fight," she said. "We have to do what we've done all year. But we need to do a better job of team hitting, including getting our bunts down."
Bees senior right-hander Baylee Reeves, who has signed with BYU-Hawaii, allowed two runs on two hits in four innings. She walked one and fanned two, with Box Elder committing two errors in the Skyhawks' two-run fourth.
Reeves had a second-inning RBI single after Horne's one-out double.
