The Stormers were not too convicting last weekend against the Cheetahs but that could be put down to them coming back from a bye.
The Waratahs were also not too convincing as they lost 24-27 to the Bulls. In all fairness the Waratahs match last week was a lot like their season so far with many ups and downs.
The Waratahs have beefed up their forwards for this match as the Stormers are a little thin the loose forwards department.
The Bookies have given the Waratahs a 10 point start for this match - with an offer of Bet 5 and Get 50 in Bets. The Stormers have not yet lost at home this year and it's unlikely the Waratahs will change that. The Stormers should win by 7.
