The victory helped Linton-Stockton remain atop the Southwestern Indiana Athletic Conference standings with an unblemished 5-0 mark, they are now 13-2 overall.
"I thought our kids were very good offensively," Linton-Stockton coach Joey Hart said. "We're just playing with more composure."
"The last two games we've played the sectional favorites (Linton-Stockton and Sullivan) so we see where we're at," EGHS coach Levi Carmichael said. "The boys have done a great job of executing what we've wanted them to, it's just that sometimes physical ability overshadows what we can do.
"That's what happened tonight, AK's a beast and he just took over and we had a hard time stopping him."
When the night was over the 6-8 senior finished his offensive showcase hitting 11 of 13 shots from the field, drained 10 of 11 charity tosses, made his only attempt from 3-point range and single-handedly out rebounded the Thunderbirds.
Linton-Stockton claimed a lopsided 30-12 edge on the glass.
Karazsia's overpowering performance was never more visible than in the second half where he helped his squad shake off a pesky Thunderbird team.
The Miner senior's efforts overshadowed his own teammates efforts defensively according to Hart.
"Those two do a great job of scoring, Austin and Dess (Fougerousse) are special players," Hart said. "Those other guys (Jackson) Bohnert, Ryan Woodward, Keith (Fulk) they sacrifice a ton for us to be successful as a team -- I think Dess and Austin would tell you that.
"They don't just jack up the first thing that smells like a shot. To me we're just playing so much more together and when we make mistakes we don't lose our minds like we used to, I'm just really proud of them."
They also negated the offensive explosion by Eastern Greene senior Tyler Brough in the first half -- more specifically the first quarter.
Brough who finished the night with an impressive 23 points to lead his team, scored all 13 of the Thunderbirds' markers in the opening eight minutes.
He missed only twice from the field while connecting on a pair of deuces and two more treys and a pair of free throws.
After another three and three more free tosses in the second quarter, the Linton-Stockton defense finally found a way to slow him down.
"We depended a lot on Brough tonight," Carmichael said. "And that's what senior does, he tries to carry us.
"I told them in the lockerroom there were a couple of layups that we've got to get to go in, there's a couple of shots that we've got to get to go in and tonight it just didn't at inopportune times."
Brough was held to just two more field goals the rest of the game and missed all three of his free throws in the second half.
"Brough came out and he was as good as advertised," Hart said. "We had a lot of trouble getting a handle on him."
Linton-Stockton's solid defensive efforts glared brightest in the middle two frames. That's when the Miners outscored their hosts 25-12.
"Linton was the favor and our kids wanted to defend the home court," Carmichael said. "They did the best they could and hopefully we'll get to see them in March."
After the early deadlock at 13-13, Linton-Stockton led 28-21 at the half before extending the lead to double-digits in the third quarter and led 38-25 at the final break.
"Let's face it, jump shots are harder to make when you're down 10 or 12," Hart said. "And our length really bothers other teams.
"And I thought Jackson Bohnert really stepped it up defensively, I was really pleased with all of them."
From there Karazsia was a one-man show in the final stanza. He didn't miss a shot from the field collecting four field goals and hitting all four free throws.
His only miss at the charity stripe came in the third quarter when the ball rolled around and fell off the front of the rim.
Fougerousse ended the night with 15 points and seven rebounds while Bohnert threw in six points and Bryant Jackson and Fulk added two each.
For the Thunderbirds it was seven from Kurtis Stille in support of Brough while Nathan Sparks came off the bench for six, Braydon Crowe added three and Logan Frye two.
"I thought our effort was great and I knew it would have to be," Hart said. "Levi is doing such a nice job with them.
"They made some adjustments to start the second half and you've got to give Eastern some credit, too."
Linton-Stockton captured the junior varsity contest with a 47-34 decision.
Drew Witty and Zach Johnson led the winners with 10 points each while Pierce Jackson added six and Beau Eaton added five points and the trio of Zach Riddell, Joe Dieball and Jacob Clothier finished with two each.
Cam Creager led Eastern Greene with 15 points while Camden Sego added five, Alex Brough four, Joe Smith and Devon Veatch three each and Cole Chitwood two.
The Miners return to action Saturday night when they travel to South Knox while the Thunderbirds visit Bedford North Lawrence.
