**The opening round of PRO14 Rainbow Cup SA action threw up plenty of talking points, from Reniel Hugo’s stunning hat-trick to the DHL Stormers’ red-card double.** Those incidents contributed to an absorbing day of action on Saturday and set the tone for what should be a keenly-contested battle among the South African sides over the coming weeks. Here, we take a look at five things we learned from the opening round. **Hat-trick hero Hugo a handful** The Cell C Sharks’ comeback victory over the Stormers owed much to a remarkable six-minute hat-trick from second row Hugo. He only joined the Sharks from the Cheetahs in February but has wasted no time in making his mark. “It was a big turning point,” said Sharks coach Sean Everitt. “We were quite fortunate when the ball came off a Stormers player for one try but I think Reniel put in a really good performance generally all around the field. “His work rate was extremely high and that's why we brought him to the Sharks.”
