Rolston dropped .26 seconds in her 500-yard freestyle event and took first-place overall with a time of 6 minutes, 13.14 seconds.
“She had an awesome night swimming personal bests in all her events,” said Spring Lake coach Kim Arnold.
“We have had a great week and a half of practice since our last meet and it showed last night. The whole team went into last night’s meet ready to swim and dive and it showed. I couldn’t be more proud of my girls and they all dropped time.”
Sophia Kleinheksel also had a big night for the Lakers, as she captured first-place in the 200 freestyle at 2:15.36, won the 50 freestyle in 28.12, and swam legs on Spring Lake’s victorious 200- and 400- freestyle relays.
Roxane Strobel also swam to victory in the 100 breaststroke (1:18.39).
In diving, the Lakers swept the top three spots, with Paige Rubleski taking first with an overall score of 171.05.
“In (finishing 1-2-3), they all picked up their first regional score,” said Lakers’ diving coach Barb Brackett. “It takes five to go to regionals.”
Makayla Boyink was in second with a score of 166.55, while Shelby Munch recorded a personal-best score of 153.55 and placed third.
“The girls have been working really hard on some new, harder dives and it has paid off,” Brackett said.
Spring Lake returns to action on Tuesday, as it travels to neighboring rival Grand Haven.
