Kenneth Rosenberg: Everything you need to know

Rosenberg agreed to a contract with the KBO's Kiwoom Heroes on Monday, Dan Kurtz of MyKBO.net reports. Rosenberg didn't find much success with the Angels during the 2024 campaign, posting a 6.00 ERA and 1.50 WHIP with a 17:8 K:BB across 24.0 innings. His KBO contract includes a $700,000 base salary with up to $100,000 in incentives, per Kurtz.

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.

Rosenberg was called up 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, posting a 3.73 ERA and 1.21 WHIP with 31 strikeouts over 31.1 innings in five starts since being optioned. The southpaw has produced a 6.87 ERA over 18.1 innings in four appearances, including a start, with the Angels this season. In a corresponding move, right-hander Caden Dana was optioned to Double-A Rocket City on Monday.
