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 scored a hat-trick as Northampton secured maximum points from their first two European games with an eight-try thrashing of Pretoria.
Ollie Sleightholme scored two tries and Henry Pollock scored the bonus point try inside an hour as a commanding Saints team ran riot in the second half.
The Bulls were still in the game with the score 14-5 at the break but a sin-binning to forward Alulutho Tshakweni in the 53rd minute for a needless trip proved very costly and they did not score a point in the second half.
International Smith contributed 10 points from the tee as Saints moved to the summit of Pool Four on superior points difference from holders Bordeaux with both sides on 10 points.
The nature of this victory, following a 35-27 away win 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 in this campaign.
Pretoria's number ten Wolhuter failed with an early penalty before Saints opened the scoring when Pollock broke before feeding Ollie Sleightholme who showed his pace to sprint away to the line.
But an mistake from the winger allowed the Bulls back into the game as the ball was knocked on in the tackle, allowing Bulls wing Stravino Jacobs to kick on and show electric speed of his own to reply after 22 minutes.
Ten minutes later, Northampton had their second as quick hands from 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 on top in both ball and field position and were being given a helping hand 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 Smith was again the creator, darting inside to deceive the advancing defence before sending a perfectly weighted grubber kick over the line for Hendy to grab his second try and Northampton's third score.
Bulls prop Tshakweni was then sin-binned for a trip on Iyogun. Tshakweni was insistent he had been reacting to a trip just prior by Iyogun but the incident from the Northampton substitute was ruled unintentional when reviewed by the officials.
Saints capitalized of having the extra man to secure the bonus point through Pollock before Coles and Sleightholme crossed as the home team registered three tries in five frantic minutes.
Hendy completed his triple with twelve minutes left on the clock and Kemeny strolled in for the eighth try of an outstanding afternoon for Northampton in the dying moments.
The top two teams in the group meet in a rerun of the previous season's final when the Investec Champions Cup returns in January as Saints head to Bordeaux. Northampton then round off the pool stage with a home game against Scarlets on January 18th.
The Pretoria Bulls, who have one point from two matches, host Bristol next before an away trip Pau.
