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 secured a perfect ten points from their first two European games with an eight-try hammering of Pretoria.
Ollie Sleightholme scored two tries and Pollock scored the fourth try before the hour mark as a dominant Northampton side cut loose in the second half.
The visitors 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 very costly and they did not score a point in the second half.
England fly-half Smith contributed 10 points from the tee as Northampton went top of their pool on superior points difference from defending champions Bordeaux with both sides on 10 points.
The manner of this win, following a 35-27 away win at Pau last week, means last season's runners-up Northampton could not have hoped for a better start as they aim to improve on that in this campaign.
Pretoria's number ten Kade Wolhuter failed with an early penalty before the hosts took the lead when Pollock broke before passing to Ollie Sleightholme who showed his pace to sprint away to the line.
But an mistake from the winger let the Bulls back in 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, Saints had their second as fast passing from Alex Mitchell at the base of a ruck and then Smith sent Hendy over in the corner to make it fourteen to five at the half-time whistle.
Northampton were dominant in possession and territory and were being aided from Bulls fly-half Kade Wolhuter who failed to find touch with clearing penalties to reinvite pressure onto the visitors.
That proved decisive after 48 minutes when Fin Smith was again the architect, stepping inside to wrong-foot the onrushing defense before sending a sweet left-footed kick over the line for Hendy to grab his second and Northampton's third score.
Bulls prop Tshakweni was then sin-binned for a tripping offense on Emmanuel Iyogun. The prop was adamant he had been reacting to a trip momentarily before by the Saints player but the contact from the Saints replacement prop was ruled unintentional when reviewed by the match officials.
Saints capitalized of having the numerical advantage to clinch the try bonus point through Henry Pollock before Coles and Ollie Sleightholme crossed as the home team notched three scores in five 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 dying moments.
The top two teams in the group will face off in a rematch of the previous season's final when the tournament resumes in the new year as Saints travel to Bordeaux-Bègles. Northampton then round off the pool stage with a fixture at home against the Scarlets on 18 January.
The Bulls, who have a single point from their opening two games, welcome Bristol next before an away trip Pau.
