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 a perfect ten points from their first two European games with an eight-try thrashing of Pretoria.
Sleightholme scored two tries and Henry Pollock scored the bonus point try before the hour mark as a commanding Saints team ran riot in the latter period.
The Bulls were still in the game with the score fourteen-five at the break but a sin-binning to forward Tshakweni in the 53rd minute for a needless trip proved decisive and they did not score a point in the final forty minutes.
International Fin Smith added 10 points from the tee as Northampton went top of Pool Four on superior points difference from holders Bordeaux with the two teams on 10 points.
The nature of this victory, following a 35-27 victory on the road at Section Paloise last week, means last season's runners-up Saints could not have hoped for a more ideal beginning as they look to go one better in this campaign.
Bulls fly-half Kade Wolhuter missed an early shot at goal before the hosts opened the scoring when Henry Pollock made a break before feeding Sleightholme who showed his pace to sprint away to the try line.
But an mistake from the winger let the Bulls back in as the ball was knocked on in the tackle, allowing Bulls wing Stravino Jacobs to hack the ball forward and show electric speed of his own to score after 22 minutes.
Shortly after, Northampton had their second try as fast passing from Alex Mitchell at the ruck base and then Smith put Hendy over to make it fourteen to five at the break.
Northampton were dominant in both ball and field position and were being aided from Bulls fly-half Kade Wolhuter who failed to find touch with clearing penalties to bring the pressure back on the visitors.
That proved decisive after 48 minutes when Smith was again the architect, stepping inside to deceive the onrushing defense before sending a sweet grubber kick over the line for Hendy to grab his second try and Saints' third score.
Pretoria forward Tshakweni was then shown a yellow card for a trip on Emmanuel Iyogun. The prop was insistent he had been reacting to a trip just prior by the Saints player but the contact from the Northampton substitute was ruled accidental when reviewed by the officials.
Saints seized the opportunity of having the numerical advantage to secure the bonus point through Henry Pollock before Alex Coles and Sleightholme scored as the home team notched three tries in five frantic minutes.
Hendy wrapped up his triple with 12 minutes remaining and Kemeny walked over for the eighth try of an excellent day for Northampton in the final minute.
The top two teams in the pool meet in a rerun of the previous season's final when the Investec Champions Cup resumes in the new year as Saints head to Bordeaux. Northampton then conclude the pool stage with a fixture at home against Scarlets on January 18th.
The Pretoria Bulls, who have one point from two matches, welcome Bristol next before traveling to face Pau.
