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 the Bulls.
Ollie Sleightholme scored two tries and Henry Pollock secured the fourth try inside an hour as a commanding Northampton side ran riot in the latter period.
The Bulls were still in the game with the score fourteen-five at the break but a yellow card to forward Tshakweni in the 53rd minute for a unnecessary trip proved very costly and they did not score a point in the final forty minutes.
International Smith contributed 10 points with the boot as Saints 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 Pau last week, means last year's losing finalists Northampton could not have hoped for a better start as they look to improve on that this season.
Pretoria's number ten Kade Wolhuter failed with an early penalty before Saints opened the scoring when Pollock made a break before feeding Ollie Sleightholme who demonstrated his speed to race clear to the try line.
But an mistake from Sleightholme allowed the Bulls back into the game as the ball was knocked on in contact, allowing Pretoria winger Stravino Jacobs to kick on and show electric speed of his own to reply after 22 minutes.
Shortly after, Northampton had their second try as quick hands from Mitchell at the base of a ruck and then Fin Smith put George Hendy over in the corner to make it 14-5 at the break.
Northampton were dominant in possession and territory and were being aided from the opposition fly-half Wolhuter who twice missed touch with penalty kicks to bring the pressure back on the visitors.
That told after 48 minutes when Fin Smith was again the creator, darting inside to wrong-foot the advancing defence before sending a sweet grubber kick over the line for Hendy to collect his second and Saints' third score.
Bulls prop Tshakweni was then sin-binned for a trip on Emmanuel Iyogun. Tshakweni was adamant he had been responding to a trip just prior by Iyogun but the incident from the Saints replacement prop was ruled accidental when looked at by the match officials.
Northampton seized the opportunity of having the extra man to secure the try bonus point through Pollock before Coles and Ollie Sleightholme crossed as the hosts registered three tries in five frantic minutes.
George Hendy wrapped up his hat-trick with 12 minutes remaining and Josh Kemeny strolled in for the eighth try of an outstanding day for Northampton in the final minute.
The top two teams in the pool will face off in a rerun of last year's final when the Investec Champions Cup returns in January as Saints head to Bordeaux-Bègles. The Saints then round off the pool stage with a fixture at home against the Scarlets on 18 January.
The Pretoria Bulls, who have one point from two matches, host Bristol next before traveling to face Pau.
