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
The young winger bagged a triple as the Saints made it a perfect ten points from their opening two Investec Champions Cup games with an eight-try hammering of the Bulls.
Ollie Sleightholme scored two tries and Pollock secured the bonus point try before the hour mark as a dominant Northampton side ran riot in the latter period.
The Bulls were within touching distance with the score fourteen-five at the interval but a yellow card to forward Tshakweni in the 53rd minute for a needless trip proved decisive and they failed to register a point in the second half.
International Smith added 10 points with the boot as Saints moved to the summit of Pool Four on points difference from holders Bordeaux with both sides on 10 points.
The manner of this win, following a 35-27 away win at Section Paloise previously, means last season's runners-up Northampton could not have hoped for a better start as they look to improve on that this season.
Pretoria's number ten Wolhuter failed with an early shot at goal before Saints took the lead when Henry Pollock made a break before feeding Ollie Sleightholme who showed his pace to race clear to the try line.
But an error from the winger allowed the Bulls back into the game as the ball slipped from his grasp in contact, allowing Bulls wing Jacobs to kick on and show electric speed of his own to score after 22 minutes.
Ten minutes later, Saints had their second try as quick hands from Mitchell at the ruck base and then Fin Smith sent George Hendy over in the corner to make it fourteen to five at the break.
Northampton were dominant in possession and territory and were being given a helping hand from the opposition fly-half Kade Wolhuter who failed to find touch with clearing penalties to bring the pressure back on the away side.
That told after 48 minutes when Fin Smith was again the architect, stepping inside to wrong-foot the advancing defence before delivering a sweet left-footed kick over the line for George Hendy to grab his second and Saints' third.
Bulls prop Tshakweni was then sin-binned for a tripping offense on Emmanuel Iyogun. Tshakweni was insistent he had been reacting to a trip just prior by the Saints player but the contact 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 clinch the bonus point through Henry Pollock before Alex Coles and Ollie Sleightholme crossed as the home team registered three tries in five frantic minutes.
Hendy wrapped up his triple with twelve minutes left on the clock and Kemeny walked over for the eighth and final try of an excellent day for Northampton in the dying moments.
The leading pair in the pool meet in a rematch of last year's final when the Investec Champions Cup returns in the new year as Saints travel to Bordeaux-Bègles. Northampton then conclude the pool stage with a home game against Scarlets on 18 January.
The Pretoria Bulls, who have one point from two matches, host Bristol Bears next before an away trip Pau.
