Mbuyi scored twice and added an assist in OHL Owen Sound's 5-4 overtime win over Barrie on Sunday.
Mbuyi is up to 10 goals and nine assists over 14 appearances this season. The Penguins prospect is rolling with three multi-point efforts over his last five games, though this was his first three-point game of the year. He's also brought some toughness, adding 31 PIM this season despite being a fairly small player.
