Luukkonen stopped 13 of 14 shots across 33:34 in relief during Monday's 5-3 win over Florida.
Luukkonen entered with the score tied 2-2 in relief of Colten Ellis and allowed just one power-play goal to Sam Reinhart before Buffalo reeled off three unanswered goals to close it out. The relief outing netted him the win, and he projects as the clear No. 1 in Buffalo's crease this season.
