Apr. 21: The Angels announced that Moran has cleared waivers and was outrighted to Triple-A Salt Lake.
Apr. 18: The Angels announced this evening they’ve selected left-hander Kenny Rosenberg onto the major league roster. Fellow southpaw Brian Moran has been designated for assignment in a corresponding move.
It’s the first major league call for the 26-year-old Rosenberg. Selected by the Rays in the eighth round of the 2016 draft out of Cal State Northridge, he spent five seasons in the Tampa Bay farm system. The 6’1″ hurler pitched his way as high as Triple-A Durham, where he tossed 30 2/3 innings across 14 relief appearances last season. Rosenberg posted a 2.35 ERA with an excellent 35% strikeout rate against the minors’ top hitters, but the Rays didn’t give him a big league look.
Tampa Bay also declined to protect Rosenberg from the minor league phase of last winter’s Rule 5 draft. The Angels selected him with the eighth pick in that process, and he impressed the front office enough this spring to put himself on the radar for a quick big league call. He has made just one appearance with Triple-A Salt Lake this season, working four innings of one-run ball with five strikeouts and two walks.
Rosenberg worked as starting pitcher up through Double-A in 2019. He spent most of last season in the bullpen but started his aforementioned lone appearance with the Bees thus far in 2022. Presumably, he’ll step into a multi-inning relief role for manager Joe Maddon, pairing with offseason signee Aaron Loup as the left-handed options in the middle innings.
Moran occupied that second lefty relief spot last week, heading to the majors eight days ago when the Halos lost José Quijada to an oblique strain. The 33-year-old made just one appearance, though, allowing four of five Rangers’ hitters he faced to reach base on Thursday. That was his first MLB appearance since he came out of the bullpen seven times between the Marlins and Blue Jays in 2020. The Angels have a week to trade Moran or place him on waivers.
