"In my seven years as the coach, it's by far the most special win that I've been a part of," said Lone Peak coach Matthew Bezzant at Brent Brown Ballpark.
The Cavemen (21-8) threatened in the top of the seventh, loading the bases with three consecutive singles before a groundout at second base preserved the Knights' victory.
"I just said, 'Hey, you know what guys, right now we have the lead,' " Bezzant said regarding the message was to his players in the midst of the seventh inning. "We need to worry about the guy at second base, that's the tying run. Find a way to get outs you've done it all game."
Lone Peak (21-7) captured an early one-run advantage in the second before American Fork pitcher Trell Morse an RBI single in the the fourth to tie things at 1.
After a rare overturned call at first base in the top of the fifth, which reversed an original call of "safe" to an out, American Fork's bats awakened with three consecutive triples to grab its first lead of the game, 2-1.
"I had confidence in my defense. I knew if I threw strikes, my defense would make plays behind me," Lone Peak pitcher Payton Freeman said.
In the sixth, Lone Peak pulled even at 2 on a wild pitch, which forced American Fork to call to the bullpen and insert Mick Madsen, but consecutive RBIs from Freeman who pitched a complete game on the mound and Payton Barney put the Knights ahead for good.
"Intensity," Bezzant said regarding the difference between Thursday and the regular-season bouts. "Obviously they're our rival. We know they're good. During the season we didn't match up with them intensity-wise and that's why they beat us."
The championship game on Friday at 1:30 p.m. will be another rivalry matchup. For the Cavemen to capture this first title since 2011-12, they'll need to beat the Knights, gunning for their first championship since 2009-10, twice.
