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 Northampton secured maximum points from their first two European games with an eight-try hammering of Pretoria.
Sleightholme scored two tries and Pollock scored the bonus point try before the hour mark as a dominant Northampton side ran riot in the latter period.
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 unnecessary trip proved decisive and they did not score a point in the second half.
International Fin Smith contributed 10 points from the tee as Saints went top of their pool on points difference from holders Bordeaux with both sides on 10 points.
The manner of this win, coming after a 35-27 victory on the road at Pau previously, means last year's losing finalists Northampton could not have hoped for a more ideal beginning as they look to go one better this season.
Pretoria's number ten Wolhuter missed an early penalty before Saints opened the scoring when Pollock broke before passing to Sleightholme who demonstrated his speed to sprint away to the line.
But an error from the winger let the Bulls back in as the ball slipped from his grasp in the tackle, allowing Bulls wing Jacobs to kick on and show blistering pace of his own to reply after 22 minutes.
Shortly after, Northampton had their second try as fast passing from Mitchell at the base of a ruck and then Fin Smith sent George Hendy over in the corner to make it fourteen to five at the break.
Saints were on top in possession and territory and were being given a helping hand from Bulls fly-half Wolhuter who failed to find touch with clearing penalties to reinvite pressure onto the visitors.
That proved decisive after 48 minutes when Smith was again the creator, stepping inside to deceive the onrushing defense before delivering a perfectly weighted left-footed kick over the line for Hendy to collect his second try and Northampton's third score.
Pretoria forward Alulutho Tshakweni was then sin-binned for a trip on Iyogun. Tshakweni was insistent 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 officials.
Northampton capitalized of having the extra man to clinch the bonus point through Henry Pollock before Alex Coles and Sleightholme crossed as the home team registered three scores in five minutes.
Hendy wrapped up his triple with twelve minutes left on the clock and Kemeny strolled in for the eighth and final try of an outstanding afternoon for Northampton in the dying moments.
The top two teams in the pool meet in a rematch of last year's final when the tournament resumes in the new year as Saints travel to Bordeaux-Bègles. Northampton then conclude the pool stage with a home game against the Scarlets on 18 January.
The Pretoria Bulls, who have one point from two matches, host Bristol in their next outing before traveling to face Pau.
