Penguins sign Bill Zonnon to ATO, prospect scores in AHL debut

Bill Zonnon did not wait long to make Wilkes-Barre/Scranton’s wager look worthwhile. Five days after signing an amateur tryout agreement, Pittsburgh’s 2025 first-round pick scored in his pro debut as the Penguins opened the Atlantic Division finals with a 2-0 win over Springfield at Mohegan Arena.

The goal mattered because this was never just a ceremonial late-season add. The ATO, signed May 7, was built to let Zonnon join Wilkes-Barre/Scranton for the Calder Cup Playoffs, and the timing gave Pittsburgh a first real look at one of its premium young pieces in a pro environment that rewards pace, decision-making and physical reliability. Zonnon was the 22nd overall pick last June, the second of the Penguins’ three first-round selections, and the organization has been trying to turn that deep draft class into faster on-ice development.

Zonnon’s junior numbers explain why the Penguins were willing to move quickly. The 19-year-old finished his 2025-26 regular season with Blainville-Boisbriand of the Quebec Maritimes Junior Hockey League at 14 goals and 32 assists for 46 points in just 35 games. His 32 assists tied for third on the Armada, even though he played only 35 of 64 regular-season games. In the playoffs, he pushed the offense again, leading Blainville-Boisbriand with 13 assists and finishing third on the club with 15 postseason points.

That production did not come from nowhere. The season before, with Rouyn-Noranda, Zonnon broke through for 83 points and 55 assists in 64 games. Taken together, the two years show a player who has already driven offense at a high junior level and has now been asked to translate it against AHL opponents with the season on the line.

The debut could not have been cleaner for Wilkes-Barre/Scranton. Sergei Murashov made 24 saves to backstop the shutout, and Zonnon supplied the offense in a game that gave the Penguins a 1-0 lead in the best-of-five series before Game 2 on Thursday. For a team still alive in the Calder Cup chase, the move offered both immediate help and a longer look at whether one of Pittsburgh’s top prospects can accelerate the climb. Kyle Dubas had already praised the way Zonnon worked to learn the system before arriving, and the first playoff game showed why that attention mattered.
