Edoardo Todaro scored a stunning first-half hat-trick to power Northampton Saints to a 43-28 victory over Scarlets. The 19-year-old Italian international's finishing secured a home Investec Champions Cup last-16 tie for Phil Dowson's side, who finished second in Pool 4 after Bordeaux's win over Bristol.

Scarlets needed a bonus-point win to advance but fell short despite tries from Elias, Hughes, Costelow, and Davies. Their United Rugby Championship struggles continued as they finished last in the pool, missing out on a Challenge Cup spot. The Welsh region has endured a difficult season, with narrow defeats to Pau and Bristol costing them.

Northampton now progresses to the knockout stages, aiming to go one further than last season's final appearance. The young Todaro, who made his professional debut this season, emerged as a key attacking weapon. For the Saints, attention turns to preparing for a home playoff tie in Europe's premier competition.
