**The DHL Stormers and the Emirates Lions turned the PRO14 Rainbow Cup SA upside down on Saturday as the bottom two beat the top two.** John Dobson’s Stormers made it back-to-back away victories as they saw off the Sharks to go second while the Lions served up a first defeat of the campaign for the Vodacom Bulls. Here are five things we learned from the Saturday’s action in Round 4. **Swiel the match-winner again** Tim Swiel clinched a dramatic late victory for the Stormers at the Lions last weekend, settling a 10-try thriller 39-37 in his side’s favour. And he was at it again on Saturday when he came off the bench to clinch a huge victory for the Stormers at the Sharks with a 79th-minute penalty. The result lifted the Stormers above the Sharks into second in the table on points difference.
