A powerhouse performance from American forward Samu Manoa helped Northamptonbeat Saracens 20-16 to secure a home LV= Cup semi-final on Saturday.
Manoa scored two tries and played his part in another for James Wilson as Northampton ensured they will have home advantage against Saracens when the two teams meet again in the final four.
Saracens had gone ahead with 15 minutes to go with Ben Spencer, who scored a first-half try, using his boot to take his personal tally to 16 points.
But it was not enough as Manoa had the final say with an unstoppable score in the corner.
Young Northampton fly-half Will Hooley kicked five crucial points on his debut to help ensure the victory.
