2023 Fantasy Outlook
Rosenberg spent the early part of his professional career as a starter before transitioning to the bullpen with Triple-A Durham in 2021. He did well as a reliever, but after the Angels claimed him off waivers during the ensuing offseason, they chose to move him back to into a starting role. The left-hander pitched well enough (3.16 ERA, 1.24 WHIP) at Triple-A last year to get his first major-league call-up, and he ended up hurling 10.2 frames, allowing five earned runs and posting an 8:6 K:BB. Rosenberg's fastball sits in the low-90s, so he'll need to balance it with his other offerings -- primarily a changeup and a slider -- to be effective in the majors. The change is his best pitch of the bunch, but there's nothing that truly stands out in Rosenberg's arsenal, giving him a pretty low ceiling. He was designated for assignment in December, so it's unclear if he'll be back in Los Angeles next season. If he returns, there's a slim chance he could compete for the sixth-starter job, but he's more likly to begin the campaign back in the minors. Read Past Outlooks

Strong in bulk role
Rosenberg threw five innings of scoreless one-hit ball while striking out six and walking none in a no-decision versus the Athletics on Saturday.
ANALYSIS
Rosenberg took over in the third inning after opener Andrew Wantz allowed one run over the first two frames. Rosenberg left in line for the win, but Ben Joyce melted down in the eighth inning to squander the Angels' lead. Over 33 innings, Rosenberg logged a 3.82 ERA despite a 1.48 WHIP and 29:14 K:BB across seven appearances (three starts). The 28-year-old southpaw is too old to be considered much of a prospect, but he could have a chance to compete for a rotation spot in spring training.
