Asa begins his second season with the Ducks and third in professional baseball. The right-hander pitched in 44 games with the Ducks in 2025, third-most on the team behind only Brad Case (54) and Braydon Nelson (51). He compiled a 4-3 record with a 4.57 ERA, two saves and 45 strikeouts to 19 walks over 45.1 innings of work. The Oregon native was dominant against righty hitters, limiting them to a .183 batting average during the season. He also posted a sub-3.00 ERA in May, June and August.

The 28-year-old put together a stretch of six consecutive scoreless appearances (seven innings) from May 1-20 and went eight consecutive games (nine innings) without allowing an earned run between May 29 and June 14. The righty took part in the Ducks Open Player Tryout prior to the season and earned an invite to spring training before being signed to the active roster on April 24. Asa began his professional career in 2022 with the Idaho Falls Chukars of the Pioneer League, pitching in two games.
