Hilton Head High already has clinched the top girls seed from Region 7-AAA. Bluffton High School has locked down the league's second seed.
But there is a lot more on the line in tonight's regular-season finale than first meets the eye.
Only one game separates the rival schools, meaning the Bobcats can earn a share of the region title with a victory against the visiting Seahawks. Hilton Head High, meanwhile, will try to win the league outright when the teams tip off at 6 p.m. The boys game will follow.
Even if the Bobcats (16-7 overall, 7-2 region) win tonight, the Seahawks own the region tiebreaker and will still take a No. 1 seed into next week's Class 3-A playoffs. The region title -- or at least a share of it -- is just the third in school history for the Seahawks (21-2, 8-1).

The Seahawks won the first meeting, 30-20, on Jan. 25, a game in which they held Bluffton to 14 percent shooting from the field.
In the boys game, the Bobcats will try to round out a season-sweep of Hilton Head High while keeping their chances alive for a home playoff game. After a loss at Battery Creek on Tuesday, Bluffton (11-10, 5-4) dropped to third place in the region, with the top two seeds awarded home games for the first round of the postseason.
Battery Creek can clinch the No. 2 seed with a win tonight at region-leading Lake Marion, but if the Dolphins lose, Bluffton can take over the second spot with a win against Hilton Head High.
The Seahawks (8-15, 1-8) enter tonight's game on a five-game losing streak, and they have been eliminated from playoff consideration, but they can somewhat salvage their season by earning a victory against the Bobcats, who have lost three of four.
"This game is the trophy game or the bragging rights game -- they'll be ready for it, and we'll be ready for it," Bobcats coach Brett Macy said. "And it is important to play well going into the playoffs. ... It's good that we're playing Hilton Head (High), because it means we'll be ready to play."
