Christian County scored the first 13 points of the game and went on to crush Shelby Valley 83-40 Wednesday night in the first round of the KHSAA/PNC Boys Sweet Sixteeen.
The 43-point gap was the widest margin of victory since the 2002 quarterfinals when North Hardin beat Whitesburg 92-43.
The biggest margin of victory, 64 points, came in 1916 in the first-ever tournament game, when Henderson shellacked LaGrange 78-14.
Not until the final moments did it become clear Shelby Valley would finish with more points than turnovers. The Wildcats had 35 turnovers and 34 points until Mason Bowling hit a three-pointer with 1:14 left.
Shelby Valley, which lost all of its starters from last year's state championship team, finished with 37 turnovers.
Christian County (22-9) advances to Friday's quarterfinals to face Lexington Catholic, a winner over Dixie Heights.
"They came out with a tremendous energy and effort, especially on the defensive end," Colonels Coach Kerry Stovall said of his players. "Donovan (Kates) got us going with some early threes, and they took care of the basketball game early."
Kates, a 6-foot-5 senior, and Anthony Hickey each had 16 points in the first half, matching Shelby Valley's team total.
Kates, 3-for-8 from three-point range, played only four minutes in the second half and didn't add to his point total.
Kates had no problem adjusting to Rupp Arena.
"It's just all practice and routine," he said. "So I just try to bring how we practice, try to bring it up here."
Hickey, a 5-11 senior, finished with 20 points on 7-for-11 shooting from the field. He added five assists and 10 steals in 19 minutes of play.
Nick Riley, whom Stovall calls "the reboundingest 5-11 kid I've ever seen," led Christian with nine rebounds to go along with five points.
Shelby Valley (13-18) was the surprise winner of the 15th Region. With a freshman and an eighth-grader in the starting lineup, the Wildcats could be a factor in the future.
First-year coach Greg Newsome brought seniors Rusty Roberts, Brett Reynolds and Trey Roberts to a post-game news conference and said, "I'm so proud of these young men for leading these guys back to here. They took some very young players and some very inexperienced players and, by the end of the year, they end up playing their hearts out."
Christian County, winner of three consecutive 2nd Region titles, simply had too much for Valley to handle.
Stovall used all 13 players.
"To be able to get those (starters) out early in the third quarter and have a full fourth-quarter rest, and then have (Thursday) to get our legs under us again is big. Really big," Stovall said. "They don't like it when we pull the throttle back at all. But we're here to win basketball games. We're not trying to embarrass anybody."
Christian County, which had 22 steals and 15 turnovers, finished with a 37-6 bonus in points off errors.
Rusty Roberts led Shelby Valley with nine points. Cody Belter, a 6-10 freshman, had eight points, six rebounds and three blocks.
"We were happy that we were down here, but our goal ... was to win a game," said Trey Roberts, who had three points and five rebounds. "We knew that Christian County was a good team, and we (were trying) to not turn the ball over. But they're so quick and athletic that we did turn it over and, unfortunately, that cost us the game."
