Hilton Head Christian Academy, behind freshman guard Macee Tamminen's double-double of 16 points and 11 rebounds, pulled away to a 46-34 victory over Laurence Manning in the SCISAA 3-A playoffs on Tuesday at Sumter County Civic Center.
Hilton Head advances to play in the semifinals on Friday.
The Eagles led 19-18 at halftime but outscored the Swampcats 14-7 in the third quarter to take a 33-25 lead. Tamminen scored 11 of her game-high 16 points in the quarter.
With the game tied at 19 early in the third, HHCA used an 8-0 spurt capped by one of Tamminen's two 3-point baskets in the quarter to take a 27-19 lead with 5:55 remaining in the third.
The Eagles' swarming defense forced eight of Laurence Manning's 24 turnovers in the third to help build an eight-point cushion.
Eagles coach Kenny Conroy said the strong shooting of Tamminen and pressure on the ball defensively were the main reasons why Hilton Head Christian was able to take control of the contest.
"Macee really stepped up and knocked down some big shots for us that helped turn the tide," Conroy said. "I also feel like our defensive pressure kind of wore on them a little bit. We actually switched after halftime from a 2-2-1 full-court press to a more matchup, trapping, full-court press.
"We knew if we put more pressure on their main ball handler (Maggie Eppley) and wore her down that would be tough for her making decisions down the stretch. Our defensive pressure made them go faster than they wanted to go."
The Lady Eagles built the biggest lead of the game of 39-25 in the final stanza on an uncontested layup by reserve junior guard Hannah Reynolds with 5:45 left to play. Laurence Manning cut the deficit to 39-31 with 3:18 remaining in the game, but it was as close as the Swampcats got.
Ziaira Doe added 12 for the Eagles, while Andy Anderson added nine.
