Zherenko signed a professional tryout agreement with Ottawa on Wednesday.
Zherenko spent the past four years in the minors with AHL Springfield. In 2025-26, he posted a 17-16-5 record and a .902 save percentage in 42 regular-season contests. With a crowded crease in front of him, including three netminders already under contract with the Senators, the best Zherenko can probably expect is to play to earn himself a two-way contract or a minor-league deal from AHL Belleville.
