Melvyn Jaminet enjoyed a 100 per cent success rate with the boot as he seized his chance in the absence of Thomas Ramos and Romain Ntamack to lead Toulouse to a 19-17 win over Top 14 champions Montpellier on Sunday.
Jaminet succeeded with all five of his kicks at goal as the 21-time champions of France went top of the table, moving a point ahead of European champions La Rochelle.
Jaminet took over kicking duties with French star Ramos starting on the bench and fellow international back Ntamack rested.
His personal 14-point haul was highlighted by a monster 60-metre penalty which secured the victory and allowed the 23-year-old fullback to keep up his perfect kicking record since moving to Toulouse from Perpignan in the summer.
Toulouse enjoyed a flying start to the game when centre Dimitri Delibes scored a try after sprinting away from the halfway line.
However, Montpellier edged ahead by the break thanks to tries from fullback Anthony Bouthier in the eighth minute and prop forward Enzo Forletta plunging over just before the half-hour mark.
The boot of Jaminet proved decisive in the second period although Toulouse's evening ended on a low note when replacement lock forward Emmanuel Meafou was red-carded.
