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.

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: Tosses five innings in long relief
Rotowire
Rosenberg allowed one run on two hits and two walks while striking out four batters over five innings in long relief against Toronto on Tuesday.
Angels starter Carson Fulmer was able to go just three innings, giving up five runs while tossing 75 pitches. Rosenberg -- who was recalled from Triple-A Salt Lake earlier in the day -- stepped in and logged what was essentially a starter's workload with 78 pitches of his own, and he was much more effective than Fulmer in yielding just one run across five frames. Due to the large workload, Rosenberg will presumably now be unavailable for several days, so he could move back to the minors in short order to allow Los Angeles to bring up a 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: Drawing start Thursday
Rotowire
Rosenberg will start Thursday's game versus the Athletics, Jeff Fletcher of The Orange County Register reports.
Rosenberg has made two appearances in long relief this month, allowing seven runs with a 7:4 K:BB over 10 innings. He had been starting at Triple-A Salt Lake prior to getting called up July 10 and threw 95 and 69 pitches in his two relief appearances with the big club. As such, Rosenberg should be able to handle a standard starter's workload against Oakland.

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.

The Angels recalled Rosenberg from Triple-A Salt Lake on Wednesday.
Rosenberg has spent all season in the minors, where he's posted a 3.74 ERA and 1.23 WHIP across 77 innings over 14 starts. Although he's served exclusively as a starter during his time in Salt Lake this year, he'll likely be moved to the bullpen upon joining the Angels.

Angels' Kenny Rosenberg: Back in action for Triple-A club
Rotowire
Triple-A Salt Lake reinstated Rosenberg (undisclosed) from the 7-day injured list Friday.
In his return from a three-week absence, Rosenberg stepped right back into the Salt Lake rotation, covering four innings while giving up one run on three hits and no walks while striking out five in the club's 12-11 loss to Albuquerque in 11 innings.

Angels' Kenny Rosenberg: Shut down at Triple-A
Rotowire
Triple-A Salt Lake placed Rosenberg on its 7-day injured list June 12 with an unspecified injury.
Salt Lake moved Rosenberg to the IL the same day it brought back another member of its rotation (Andrew Wantz) from the IL. Rosenberg made 10 appearances (four starts) with the Angels over the past two seasons and remains on the 40-man roster, but he had been pitching exclusively for Salt Lake in 2024 before landing on the shelf. Though 12 starts in the Pacific Coast League covering 68 innings, Rosenberg owns a 3.84 ERA, 1.31 WHIP and 56:24 K:BB.

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: Strong in bulk role
Rotowire
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.
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.

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.

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.

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.
