Casey connected on nine of 15 shots during the first frame and collected six assists in the process.
"We shot the ball very well, especially from 3-point range," Casey coach Randy Salyers said. "That was the key to the game. We just shot it so well and moved the ball around and found the open shot.
"Defensively, our rotation on our zone was outstanding during the first half. We normally don't play zone, but we have had some illnesses and Tara (Weddle) had a sprained ankle, and we wanted to give them a bit of a rest."
Casey shot 45 percent (25-for-55) overall from the field and had 17 assists.
Weddle and Megan Pittman led the Lady Rebels with 12 points each.
From bad to worse
Things went from bad to worse for Garrard in the second quarter when the Lady Lions turned the ball over 10 more times and finished the first half with only 13 shot attempts.
Meanwhile, Casey continued to scorch the nets with 53 percent shooting and led 43-15 at halftime. The Lady Rebels hit 17 of 32 shots from the field - including six of 14 from 3-point range - and had 11 assists by halftime.
Garrard, however, picked up its defensive intensity during the second half and played much better.
"We did play better during the second half," Harris said. "But it's hard to come back when you are down that far. We work on our shooting everyday in practice, and it's hard to see that we are getting any benefit from it. Part of that is youth, and it is beginning to show."
Casey led by as many as 38 points during the second half, and Salyers went to his bench frequently, trying different lineup combinations.
"It's good to get back to playing again after being off for eight days," the Casey coach said. "It was a good win for us."
While Casey shot 45 percent from the field, Garrard was as cold as the weather outside at a frigid 21 percent (8-for-38). The Lady Lions hit 13 of 25 free throws, while Casey was 10-for-18 at the line.
Alexis Anderson was Garrard's high scorer with nine points.
Casey won the rebounding battle 43-30, led by Nicole Coffman with eight boards. Emiley Meadows had eight rebounds for Garrard, which had 24 turnovers compared to 16 for Casey.
