Dunn will throw a bullpen session in front of scouts Tuesday in Phoenix, Jon Heyman of the New York Post reports.
Dunn, 29, didn't pitch at all in 2024 and threw just 3.1 rehab innings in 2023 due to a right shoulder issue which eventually required surgery to repair a torn anterior capsule. He's evidently healthy now and will hope to convince a team he's worthy of another opportunity. The 2016 first-round pick has a career 4.44 ERA and 113:86 K:BB over 133.2 innings covering parts of four major-league seasons.
