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 maximum points from their opening two European games with an eight-try hammering of the Bulls.
Ollie Sleightholme crossed twice and Henry Pollock scored the bonus point try inside an hour as a commanding Northampton side ran riot in the latter period.
The Bulls were within touching distance with the score 14-5 at the break but a yellow card to forward Tshakweni in the 53rd minute for a unnecessary trip proved decisive and they failed to register a point in the final forty minutes.
International Smith added 10 points from the tee as Saints went top of their pool on superior points difference from holders Bordeaux-Bègles with both sides on 10 points.
The nature of this win, following a 35-27 away win at Section Paloise last week, means last season's runners-up Saints could not have asked for a better start as they aim to go one better this season.
Pretoria's number ten Wolhuter failed with an early shot at goal before Saints opened the scoring when Pollock made a break before feeding Sleightholme who showed his pace to sprint away to the line.
But an mistake from Sleightholme let the Bulls back in as the ball was knocked on in contact, allowing Pretoria winger Stravino Jacobs to kick on and show blistering pace of his own to score after 22 minutes.
Shortly after, Saints had their second try as quick hands from Alex Mitchell at the base of a ruck and then Smith sent George Hendy over to make it 14-5 at the half-time whistle.
Northampton were dominant in possession and territory and were being aided from the opposition fly-half Kade Wolhuter who twice missed touch with penalty kicks to reinvite pressure onto the visitors.
That proved decisive after 48 minutes when Smith was again the creator, darting inside to wrong-foot the onrushing defense before sending a sweet grubber kick over the line for George Hendy to collect his second and Northampton's third score.
Pretoria forward Alulutho Tshakweni was then shown a yellow card for a tripping offense on Iyogun. The prop was adamant he had been reacting to a trip momentarily before by Iyogun but the incident from the Northampton substitute was ruled unintentional when reviewed by the match officials.
Northampton capitalized of having the numerical advantage to secure the try bonus point through Henry Pollock before Coles and Sleightholme crossed as the hosts registered three tries in five frantic minutes.
Hendy wrapped up his hat-trick with twelve minutes left on the clock and Kemeny walked over for the eighth and final try of an excellent afternoon for Northampton in the final minute.
The leading pair in the pool will face off in a rematch of the previous season's final when the tournament returns in the new year as Northampton head to Bordeaux-Bègles. The Saints then round off the pool stage with a home game against Scarlets on 18 January.
The Pretoria Bulls, who have one point from their opening two games, welcome Bristol Bears next before traveling to face Pau.
