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 scored a hat-trick as the Saints made it a perfect ten points from their opening two European games with an eight-try thrashing of the Bulls.
Ollie Sleightholme scored two tries and Pollock scored the fourth try before the hour mark as a dominant Saints team cut loose in the second half.
The visitors were within touching distance with the score fourteen-five at the interval but a sin-binning to forward Tshakweni in the 53rd minute for a unnecessary trip proved very costly and they failed to register a point in the final forty minutes.
International Smith added 10 points with the boot as Northampton moved to the summit of Pool Four on points difference from defending champions Bordeaux with the two teams on 10 points.
The manner of this victory, following a 35-27 victory on the road at Pau previously, means last season's runners-up Northampton could not have asked for a more ideal beginning as they aim to improve on that this season.
Pretoria's number ten Kade Wolhuter failed with an early shot at goal before Saints took the lead when Henry Pollock made a break before passing to Sleightholme who demonstrated his speed to race clear to the try line.
But an mistake from the winger allowed the Bulls back into the game as the ball was knocked on in the tackle, allowing Bulls wing Stravino Jacobs to kick on and show electric speed of his own to score after 22 minutes.
Shortly after, Saints had their second try as quick hands from Mitchell at the base of a ruck and then Fin Smith put George Hendy over to make it fourteen to five at the break.
Northampton were dominant in possession and territory and were being aided from Bulls fly-half Kade Wolhuter who failed to find touch with penalty kicks to bring the pressure back on the away side.
That told after 48 minutes when Fin Smith was again the creator, stepping inside to deceive the onrushing defense before sending a sweet left-footed kick over the line for George Hendy to collect his second and Saints' third score.
Bulls prop Tshakweni was then shown a yellow card for a tripping offense on Iyogun. The prop was adamant he had been reacting to a trip just prior by Iyogun but the incident from the Northampton substitute was ruled accidental when looked at by the match officials.
Saints capitalized of having the numerical advantage to clinch the bonus point through Henry Pollock before Coles and Ollie Sleightholme scored as the hosts notched three scores in five frantic minutes.
Hendy wrapped up his hat-trick with twelve minutes left on the clock and Kemeny walked over for the eighth try of an outstanding day for Northampton in the final minute.
The top two teams in the group meet in a rerun of the previous season's final when the Investec Champions Cup returns in the new year as Saints travel to Bordeaux. The Saints then conclude the group phase with a home game against the Scarlets on 18 January.
The Pretoria Bulls, who have one point from their opening two games, host Bristol Bears next before traveling to Pau.
