The Deasons combined for 48 points -- Kendal had 27 and Kent 21 -- in Kelly's 72-53 win over Scott City.
"They're senior leaders and we expect them to step up and be big," said Kelly coach Cory Johnson.
With the win, the Hawks look like a great fit for the Christmas Tournament's Cinderella slipper.
Coming in as a seventh seed, Kelly knocked off perennial tournament contender and No. 2-seed Charleston in the quarterfinals and now No. 3 Scott City in the semifinals.
"I told the guys the other night that every tournament's got to have a Cinderella and why can't it be us," said Johnson. The Hawks, who improved to 7-3 with their sixth straight win, got off to a sluggish start against Scott City but picked it up in the second quarter to erase a 14-7 deficit and surge to a 31-25 halftime lead.
"We came out prepared, but just not focused in the first quarter," said Johnson, "then we gained our composure and knew that seven points wasn't a deficit that we couldn't overcome, especially the way we've played the last four or five ballgames."
With sharpshooters Kendal and Kent Deason hitting big shot after big shot, Kelly controlled the tempo in the second half.
"We just move around, look for the open shot or dribble penetration when we've got it and try to score," said Kent Deason, who buried five 3-pointers. Kendal sank three. Equally instrumental in keeping the Rams at bay was the Hawks' relentless, hustle, which, seemingly, corralled every loose ball and grabbed every rebound, setting up many second-chance shot opportunities.
"We pride ourselves on outplaying people," stressed Johnson. "We're not tall, we're not a big team, but we can play physical. Getting to loose balls and rebounds gives you a lot of momentum and that puts the other team in a hole. It's tough to climb out of a hole when you have to foul."
Kelly led 45-40 as the third period ended, then extended the margin throughout the fourth quarter to win going away. The Deasons tallied 21 of Kelly's 27 fourth-quarter crunch-time points.
All-stater Mark Dannenmueller scored 27 points and teammate Mark Johnston added 16 for the Rams, who fell to 5-4. Scott City will play Cape Central, a 75-49 loser to Jackson, for third place at 6:30 tonight.
Kelly, in its first final appearance since 1997, meets Jackson for the championship at 8 p.m.
"We're definitely on Cloud Nine right now," said Kendal Deason, following the Hawks' impressive victory. "We've played hard and played together this whole tournament and that's what we look to do tomorrow."
Charleston jumped out to a 20-12 first-quarter lead and cruised to a 71-46 victory over Advance in a winners bracket consolation semifinal on Wednesday.
The win pits the Bluejays against Scott County Central, a 69-65 winner over Bell City for fifth place.
"We played much better tonight," said Charleston coach Danny Farmer. "That loss last night (65-60 to Kelly) really kind of woke the kids up and they came out and played a good defensive game tonight. We were also a lot more patient on offense. I was pleased with the effort."
The Bluejays had four players in double digits, led by sophomore point guard Shawn Sherrell's 29.
Sophomores Jamarcus Williams and Justin Clark scored 12 and 10, respectively, while senior post Ashton Farmer added 10, also.
Sherrell's performance on the offensive end, which included three 3-pointers, was especially pleasing to coach Farmer. "He (Sherrell) stepped it up," he said. "Sherrell and Clark are going to have to hit outside shots because Ashton (Farmer) will be triple teamed every night."
The Hornets never really got it going. They fell behind early and never closed within 10 points. Leading 42-32 in the third quarter, the Bluejays shut the door with an 11-0 run to close out the period.
Junior guard Daryl Wade paced the Hornets, who were eliminated with the loss, with 16 points.
