Investec Champions Cup Pool Four
Northampton Saints (14) 50
Tries: Sleightholme 2, Hendy 3, Pollock, Coles, Kemeny Cons: Smith 5
Pretoria Bulls (5) 5
Tries: Jacobs
George Hendy bagged a triple as the Saints made it maximum points from their opening two European games with an eight-try thrashing of the Bulls.
Sleightholme crossed twice and Pollock scored the bonus point try before the hour mark as a dominant Saints team ran riot in the latter period.
The visitors were still in the game with the score 14-5 at the break but a yellow card to forward Tshakweni in the 53rd minute for a unnecessary trip proved decisive and they failed to register a point in the final forty minutes.
International Fin Smith added 10 points with the boot as Saints went top of their pool on superior points difference from defending champions Bordeaux with both sides on 10 points.
The nature of this win, coming after a 35-27 victory on the road at Section Paloise previously, means last year's losing finalists Saints could not have asked for a better start as they look to improve on that in this campaign.
Bulls fly-half Kade Wolhuter missed an early shot at goal before Saints took the lead when Pollock broke before feeding Sleightholme who showed his pace to sprint away to the try line.
But an error from Sleightholme allowed the Bulls back into the game as the ball slipped from his grasp in the tackle, allowing Pretoria winger Jacobs to hack the ball forward and show blistering pace of his own to reply after 22 minutes.
Shortly after, Northampton had their second as quick hands from Mitchell at the base of a ruck and then Fin Smith put George Hendy over to make it 14-5 at the half-time whistle.
Northampton were on top in possession and territory and were being aided from Bulls fly-half Wolhuter who twice missed touch with penalty kicks to bring the pressure back on the visitors.
That told after 48 minutes when Smith was again the architect, stepping inside to wrong-foot the onrushing defense before delivering a sweet left-footed kick over the line for Hendy to grab his second try and Saints' third score.
Bulls prop Tshakweni was then sin-binned for a tripping offense on Iyogun. Tshakweni was adamant he had been reacting to a trip momentarily before by the Saints player but the contact from the Northampton substitute was ruled accidental when looked at by the match officials.
Northampton capitalized of having the numerical advantage to secure the bonus point through Henry Pollock before Coles and Ollie Sleightholme scored as the hosts notched three scores in five minutes.
George Hendy wrapped up his triple with twelve minutes left on the clock and Josh Kemeny walked over for the eighth and final try of an outstanding afternoon for Saints in the final minute.
The top two teams in the group meet in a rematch of last year's final when the tournament resumes in the new year as Northampton travel to Bordeaux. Northampton then conclude the pool stage with a home game against Scarlets on 18 January.
The Bulls, who have a single point from their opening two games, host Bristol next before traveling to face Pau.
