NHL 'PTO' tracker: Hurricanes sign Zach Aston-Reese to professional tryout

The NHL's free agent frenzy is long over, with teams now firmly setting their sights on training camps later this month.

But before camps begin, unsigned players have one last chance to try and crack a roster for the 2023-24 season. In the weeks leading up to camp every year, a number of veterans sign professional tryout agreements (also known as PTOs). These agreements often don't bear any fruit, but teams occasionally strike gold and end up landing a contributor.

Here are all the players who have committed to PTOs thus far:

Anaheim Ducks

Zack Kassian, Forward: Kassian has carved out a lengthy NHL career and will try to crack the Ducks' roster after being bought out by the Arizona Coyotes this offseason. He won't be expected to score 15 goals like he did twice with the Edmonton Oilers, but he'll add some grit to a young team.

Arizona Coyotes

Ryan Dzingel, Forward: Dzingel has over 400 games played at the NHL level, last appearing for the Coyotes and San Jose Sharks in 2021-22. The 31-year-old was in Carolina's camp last year on a two-way deal but didn't make the team.

Peter Diliberatore, Defense: Diliberatore split last season between the AHL and ECHL, playing for the affiliates of the Vegas Golden Knights and Pittsburgh Penguins. He was a sixth-round pick of the Golden Knights in 2018.
