The Lady Pirates hit several 3-point shots in the first half to keep pace with Sallisaw, which led 24-23 at halftime.
After the break, the Lady Diamonds turned up their defensive intensity and held Poteau without a field goal for the entire third quarter while allowing just one free throw during the eight-minute span.
Sallisaw took advantage of the Poteau drought to build a 33-24 lead entering the fourth quarter and held on to run its record to 15-3 overall and 8-0 in the league. That clinched the NOAA title with two games left to play.
Junior Caitlyn Hall scored a team-best 13 points to lead the Lady Diamonds, while Ashley Covington and Sarah Snider both hit double figures with 10 each. Meghan Smith chipped in seven points, Lyndsey Daggs three and Mayra Salazar two.
Poteau was led by 14 points from Cheyenne McConnell, but couldn't overcome an early Sallisaw run that saw the visitors grab a quick 7-0 lead.
Sallisaw never trailed in the game.
