"For a team that's shooting 29 percent for the year, that's huge," Mason said. "I think they've been thinking about their shot instead of just shooting it. Tonight they just shot."
They also defended well, as Garrard committed 30 turnovers and shot just 26.3 percent.
Garrard coach Jenny Teater was not available for comment after the game.
"We knew if we had a game where we were all on, nobody could stop us," said forward Ashley Chalk, who led Boyle with 16 points and eight rebounds. "Our practices have been better in the past week. It was just time for a win, and we all knew it."
It was the first win for Boyle since it beat Western Hills Dec. 21. In the 12 games that followed, the Rebels lost by an average of 16.7 points and failed to break 40 five times.
"It was looking like we were never going to win," Chalk said.
Mason even confessed to some private doubts.
"Maybe a little bit, because I haven't ever gone a month and a half without a win," she said. "But to them I had to be positive."
Mason said she saw the first sign that Boyle's fortunes might be taking a turn for the better when the Rebels scored 26 points in the third quarter Monday at Russell County.
"That's where we picked up and started playing," she said.
It happened again against Garrard, as Boyle scored 24 points in the third period - one more than it had in the first half - to take a 47-32 lead.
"I'm going to have to give my halftime speech before the game," Mason said. "It wasn't very pretty. I went in there with one clipboard, and I brought out three."
Rebels go on run at beginning of second half
Boyle brought out its best game at the start of the second half, outscoring Garrard 11-1 in the first three minutes to go up 34-25.
Chalk scored the first two baskets of the half, one after she stole the ball on Garrard's first possession and one after Tiffany Webb stole it on the next.
Chalk had two baskets in each quarter and was 8-for-13 from the field in what she called her best game of the season.
"I've got to have a standout player, and I haven't had one all year," Mason said. "Ashley's so athletic, I think she can be that player for us. I feel like she can take anybody off the dribble when she's in control."
Boyle took control in the third quarter only because the Lady Rebels picked up the pace after settling for a half-court game in the first half.
They led by five points twice in the second quarter after erasing Garrard's early 10-4 lead, but Mason said they didn't hit their stride until after halftime.
"We're not a half-court team," Mason said. "In the third quarter we played our game. I thought (point guard) Allie (Hafley) in the second half really took some leadership when she pushed the ball up the floor, and that was the difference."
Garrard committed nine turnovers in the third quarter and nine more in the fourth.
"I think we definitely played good defense tonight," Chalk said. "We were shooting the seams, getting on our toes, and that's what we needed to get to their passes."
Garrard got off just 38 shots - 17 fewer than Boyle - and hit only 10.
Boyle was 22-for-55 from the field, including 5-for-14 from 3-point range. Four of its 3s came in the third quarter, and Cierra Leffew, Amber Mills and Stephanie Elks produced three of them in less than two minutes to stretch the lead to 47-32.
The Lady Rebels committed 14 of their 26 turnovers in the fourth quarter, but many of those came as Mason began to rotate reserves into the game.
Andrea Adams led Garrard with 14 points. She and teammate Wendy Logan had seven rebounds each.
