Bubba Wright won his 160-pound bout by major decision, 13-2. Riley Williams won a close 1-0 decision at 170 pounds, and Josh Latham pinned his opponent in the first period.
"Josh knew he could go out there and get the pin," Randle said. "We knew who their tougher kids were."
Sam Richardson was in control for a majority of his match at 195 pounds against Marcus Stewart, leading 6-3 after two periods. However, Stewart scored a near fall at the buzzer of the third period to force overtime.
In the overtime, Stewart scored a takedown with 37 seconds left in the period.
"Sam's not where he needs to be with his legs yet," Randle said. "He really kind of let up. He should've won the match, but one of the things I told him was that he couldn't get pinned. That was one of their good kids, also.
Chickasha forfeited at 220 pounds before Brown closed out the dual win with his fall victory.
"I knew that with Jacoby going at the end, and they didn't have a great heavyweight, that the outcome was going to be inevitable," Randle said.
After the match, Randle was pleased with a victory over Duncan, a team Chickasha has struggled with in the past.
"I'm always finding faults, but like I told them, it's an accomplishment and there is some pride to take in beating Duncan," Randle said. "We haven't beaten them in a while. We can take a little satisfaction in that, then we've got to get our minds on the Deer Creek tournament after that."
The Fightin' Chicks began competition at the Deer Creek Invitational on Friday, and will also wrestle all day Saturday.
