That is when everything changed for Whakarewarewa.
The next kick-off was re-gathered by Sports as visiting halfback Akira Mako stood behind his opponent's posts in the bin. A penalty goal to Lewis Hancock came next, followed by more penalties and the further sin-binning of Whakarewarewa's John Ririnui upon Mako's return.
A late converted Hancock sideline try after a slick Sports backline move gave the hosts a 13-12 halftime lead.
A leg injury to Craft-Chemis - who had been in everything up until that point - took some of the steam out of the visitors as the wind picked up behind Sports in the second stanza.
A pair of penalties to the accurate Hancock made it 19-12 before a George Honey try looked to ice it after 72 minutes.
Whakarewarewa burst back into the match a minute later when the dangerous Chanse Perham barged over, but they ultimately ran out of time and patience with the officiating.
Hancock, who collected 19 points in a composed performance at the back, said the side had placed great importance on the home match against the former competition leaders after being tipped over by Te Puke Sports earlier in the weekend.
"That would have managed to put us way down the chain if we had managed to lose today," Hancock said. "I think there were a few sore bodies but we tried not to think about it. "
