Tropeano returns for his second season with the Ducks and 14th in professional baseball. The righty has seven seasons of Major League experience, pitching with the Houston Astros (2014), Los Angeles Angels (2015-16, 2018-19), Pittsburgh Pirates (2020), San Francisco Giants (2021) and New York Mets (2021). In 54 games (39 starts), the West Islip, N.Y. native compiled a 14-14 record with a 4.22 ERA and 214 strikeouts to 94 walks over 241.0 innings. He earned the win in his MLB debut on September 10, 2014, tossing five innings of two-run ball in a 5-2 road victory over the Seattle Mariners.

The 34-year-old made 15 appearances (six starts) for the Flock in 2024, totaling a 4-2 record with a 5.48 ERA and 39 strikeouts to 23 walks over 46.0 innings of work. He allowed three earned runs or less in each of his first five starts with the team, earning four wins in that span, and posted a 4.50 ERA overall as a starter. Previously, the West Islip High School alum earned Baseball America Triple-A All-Star and Pacific Coast League All-Star honors in 2014 as well as South Atlantic League All-Star honors in 2012. Tropeano was originally selected by the Astros in the fifth round of the 2011 amateur draft from Stony Brook University.
