They took precautions, such as holding the finals at different times to limit crowd numbers.
Scorer Leesa Kingi said Scorpions were two runs down when Yuko Beattie stepped up to the plate in the seventh inning.
She had runners on the second and third bases and her hit got them home, as well as herself, for the winning run.
“It was so close all the way,” Kingi said.
An error by Scorpions gave Rovers the advantage and it looked like Rovers would hold on, but they couldn't quite do so.
Hinemoa Sidney went well at first base and Jana Hihi did well as pitcher, Kingi said.
Te Ratahi Campbell pitched well for Rovers, she said.
TWK Rams were up 7-1 in the men's final and looked to be cruising to victory.
But Spartans came right back into it, closing the gap to 7-6 and with time left to finish the job.
“The Rams had to hold off for two full innings,” Kingi said.
The final stages had plenty of tension.
“That game nearly gave me a heart attack,” said Kingi, who has family links with the Rams.
Xavier Kingi and Corey Boocock hit home runs and Rongo Rapaea brought runners home for the Rams.
Kingi said Shaquaid Hihi pitched well for Spartans.
