The Angels released Rosenberg on Monday.
Rosenberg appeared in seven regular-season games (including one start) for the Angels in 2024 and posted a 6.00 ERA and 1.50 WHIP over 24 frames. He spent most of the year with Triple-A Salt Lake, and across 21 starts he posted a 9-7 record with a 4.21 ERA, 1.30 WHIP and 105:38 K:BB over 115.1 innings. The 29-year-old southpaw should receive interest from organizations looking to bolster its left-handed pitching options.

Angels' Kenny Rosenberg: Called up Monday
Rotowire
The Angels recalled Rosenberg from Triple-A Salt Lake on Monday.
Rosenberg will return to the major-league roster after being sent down to Salt Lake on Aug. 14. He posted a 3.73 ERA and 1.21 WHIP with 31 strikeouts over 31.1 innings in five starts since being optioned, but the southpaw could work out of the bullpen while he's back up with the Angels. The Angels optioned starter Caden Dana to Double-A Rocket City on Monday, but the club could roll with a five-man rotation over the final two weeks rather than having Rosenberg replace Dana as a sixth starter.

Angels' Kenny Rosenberg: Back in minors
Rotowire
The Angels optioned Rosenberg to Triple-A Salt Lake on Wednesday.
Rosenberg threw five innings of one-run ball during his long-relief appearance Tuesday. He'll now be sent back to Triple-A in favor of Brock Burke, who was claimed off waivers from Texas on Tuesday and will provide the Halos' bullpen with another fresh arm.

Angels' Kenny Rosenberg: Recalled from Salt Lake
Rotowire
The Angels recalled Rosenberg from Triple-A Salt Lake on Tuesday.
Since being optioned to the minors July 26, Rosenberg has allowed nine earned runs in just seven innings. Despite his poor performance, he'll now rejoin the Angels and presumably serve as a long-relief option. Davis Daniel was optioned to Triple-A in a corresponding move.

Angels' Kenny Rosenberg: Hit hard in first start
Rotowire
Rosenberg (0-1) took the loss against the Athletics on Thursday, allowing six runs on six hits and one walk over 3.1 innings while striking out one.
Rosenberg struggled out of the gate, giving up a leadoff double to Lawrence Butler to open the contest before then surrendering a solo homer to Brent Rooker just two batters later. The lefty would go on to allow three homers on the night. Rosenberg had gotten through at least four innings in each of his previous two appearances, which came in relief, but he's been tagged for multiple home runs in two of his three big-league outings this season.

Angels' Kenny Rosenberg: Covers six frames in season debut
Rotowire
Rosenberg pitched in long relief against Seattle on Thursday, allowing six runs on eight hits and three walks while striking out four batters over six innings.
Jack Kochanowicz was given the start in his MLB debut but lasted just three innings, giving up five runs (four earned). Rosenberg entered in the fourth and took on what amounted to a full starting workload, tossing 95 pitches (55 strikes). It was the southpaw's first big-league outing of the season, but he was ready to handle the hefty workload since he was a starter in all 14 of his appearances with Triple-A Salt Lake. Given his usage Thursday, it wouldn't be surprising if Rosenberg is sent back to the minors in short order, since he likely won't be available to take the mound again until after the All-Star break.

Angels' Kenny Rosenberg: Optioned to Triple-A
Rotowire
The Angels optioned Rosenberg to Triple-A Salt Lake on Thursday.
To close out the 2023 season, Rosenberg logged a 3.82 ERA despite a 1.48 WHIP and 29:14 K:BB across seven appearances (three starts). The pitcher entered 2024 hoping to compete for a starting role in spring training.

Angels' Kenny Rosenberg: Picks up second win
Rotowire
Rosenberg (2-2) earned the win Saturday, allowing five hits and two walks over five scoreless innings against the Twins while striking out five.
Rosenberg was able to keep the Twins at bay despite giving up two walks and a single in the opening frame. He allowed a single in all five innings in which he appeared but was able to escape each time without sustaining any damage. The lefty has now allowed three or fewer runs in three of his four outings this month, though he's also issued at least two walks in all but one appearance this season.

Angels' Kenny Rosenberg: Falters as primary pitcher
Rotowire
Rosenberg (1-2) allowed five runs on seven hits and two walks while striking out five over five innings to take the loss versus the Tigers on Sunday.
Jimmy Herget tossed a perfect inning as the opener, but Rosenberg quickly ran into trouble after entering in the second inning. Jake Rogers took Rosenberg deep twice between the second and third frames, accounting for all but one of the runs on the southpaw's line. Through five appearances spanning 23 innings, Rosenberg has a 5.48 ERA, 1.78 WHIP and 18:12 K:BB. If he remains part of the rotation, he'd be lined up to make his next appearance on the road in Minnesota.

Angels' Kenny Rosenberg: Solid in Sunday's win
Rotowire
Rosenberg (1-1) allowed one run on six hits and a walk while striking out four over five innings to earn the win over the Guardians on Sunday.
Rosenberg limited the damage to a Kole Calhoun solo shot in the second inning. Over his last two outings, both starts, Rosenberg has allowed four runs across 11 innings with an 8:3 K:BB. He's at a 4.50 ERA, 1.78 WHIP and 15:10 K:BB through 18 innings across four appearances overall. The 28-year-old southpaw is tentatively lined up for a home start versus the Tigers next weekend.

Angels' Kenny Rosenberg: Picks up another start
Rotowire
Rosenberg is scheduled to start Sunday's game against the Guardians at Angel Stadium.
Rosenberg will receive a second turn through the Angels' six-man rotation after he delivered a quality start against the Orioles his last time out Monday. The 28-year-old southpaw could have a clear path to a rotation spot for the remainder of the season with two-way superstar Shohei Ohtani (elbow/oblique) having been shut down from pitching and with Lucas Giolito having recently been waived.

Angels' Kenny Rosenberg: Records quality start
Rotowire
Rosenberg (0-1) took the loss against Baltimore on Monday, allowing three runs on seven hits and two walks while striking out four batters over six innings.
Rosenberg got his first start of the season and fared pretty well, yielding just three runs -- all in the third inning -- to finish with the first quality start of his brief big-league career. The Angels' offense was unable to reward him for it, however, and the southpaw also ended up with his first major-league loss. The Angels are short on starting pitching depth with Shohei Ohtani's elbow injury keeping him from pitching again this season, Chase Silseth on the concussion IL and Lucas Giolito recently claimed off waivers by Cleveland, so Rosenberg could stick as a starter for a bit, especially if Los Angeles continues to deploy a six-man rotation.

Angels' Kenny Rosenberg: Starting Monday vs. Orioles
Rotowire
Rosenberg is starting Monday's game at home against the Orioles, Jeff Fletcher of The Orange County Register reports.
The Angels are still hoping to avoid using their starters on four days' rest, per Fletcher, and they don't have an off day until Sept. 14; therefore, Rosenberg may get a few more starts beyond Monday. He has given up five earned runs with seven walks and seven strikeouts over seven frames in two big-league appearances this season and had a 7.20 ERA, 1.80 WHIP and 33 strikeouts over 25 innings in his five most recent Pacific Coast League starts.

Angels' Kenny Rosenberg: Recalled from Triple-A
Rotowire
The Angels recalled Rosenberg from Triple-A Salt Lake on Tuesday.
Chase Silseth is going on the 7-day concussion injured list in a corresponding move after taking a throw to the head Saturday against the Mets. Rosenberg has allowed five earned runs in seven major-league innings this season and figures to operate in a low-leverage relief role.

Angels' Kenny Rosenberg: Returns to Triple-A
Rotowire
The Angels optioned Rosenberg to Triple-A Salt Lake on Thursday.
Rosenberg was returned to Triple-A one day after he was called up and appointed as the Angels' 27th man for a doubleheader with the Reds. He covered two innings out of the bullpen in the Angels' 9-4 loss in the first game of the twin bill, giving up one earned run on two hits and two walks while striking out three.

Angels' Kenny Rosenberg: Reassigned to minor-league camp
Rotowire
Rosenberg was reassigned to minor-league camp by the Angels on Tuesday.
Rosenberg cracked the majors for the first time in his career last season, allowing five earned runs over 10.2 innings while striking out eight batters. He performed well in Triple-A last season (3.16 ERA, 1.24 WHIP) and is having a very good spring, so there is a chance Rosenberg can work his way back into the Angels' bullpen if he maintains his current pace.

Angels' Kenny Rosenberg: Clears waivers
Rotowire
The Angels outrighted Rosenberg to Triple-A Salt Lake on Monday.
He'll remain in the organization after going unclaimed off waivers when the Angels removed him from the 40-man roster last week to clear a spot for the newly signed Justin Garza. Rosenberg made three appearances (one start) for the Angels in 2022 but otherwise spent the majority of the season as a member of Salt Lake's rotation. In 62.2 innings for the Triple-A club, Rosenberg submitted a 3.16 ERA, 1.24 WHIP and 62:27 K:BB.

Angels' Kenny Rosenberg: DFA'd by Halos
Rotowire
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.

Angels' Kenny Rosenberg: Sent to Salt Lake
Rotowire
Rosenberg was optioned to Triple-A Salt Lake on Monday.
Rosenberg was called up for a spot start Sunday against Seattle and wound up throwing 4.2 scoreless innings, though his 1:3 K:BB was hardly impressive. He'll return to the minors as the Angels call up Janson Junk for added relief depth.

Angels' Kenny Rosenberg: One out short of win
Rotowire
Rosenberg allowed two hits and three walks with one strikeout over 4.2 scoreless innings in a no-decision versus the Mariners on Sunday.
Rosenberg threw 71 pitches (43 strikes) in his first big-league start. He performed well but fell one out shy of qualifying for the win. He'd given up five runs in six innings across two relief appearances earlier in the season, though he's pitched well as a starter in the minors, logging a 2.34 ERA, 0.96 WHIP and 36:12 K:BB in 34.2 innings with Triple-A Salt Lake. The southpaw appears to be in contention with Jose Suarez for the role of sixth starter in the Angels' rotation. The Angels are off each of the next two Thursdays, so it's unclear if they will turn to either Rosenberg or Suarez in a starting role in the immediate future.
