Rosenberg was designated for assignment by the Angels on Monday.
Rosenberg spent multiple brief stints in the majors during the first half of 2022, posting a 4.22 ERA and 1.41 WHIP through 10.2 innings. If he can recreate his Triple-A numbers from last season (3.16 ERA, 1.24 WHIP), there is a chance Rosenberg can find himself on the 40-man roster and in the majors next season at some point. For now, newly-signed Justin Garza will take his roster spot.
