Never miss a local story.
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.
