2025 Fantasy Outlook
It feels like Kochanowicz arrived in the major leagues about 40 years too late. Back in the 80s, a big, sturdy right-hander with good control, heavy ground ball tendencies and virtually zero swing and miss ability probably would have had a long career. In the modern game, his place is less certain, even after he managed to post a solid 3.99 ERA in 11 starts for the Angels in 2024 in spite of a microscopic 9.4 percent strikeout rate. Kochanowicz will be part of the rotation competition for the Angels in 2025 and might very well begin the season in the big leagues, but his profile gives him a very narrow path to fantasy viability.

Kochanowicz allowed four runs on six hits and two walks while striking out one batter over five innings in a no-decision against Boston on Monday.
ANALYSIS
Though Kochanowicz issued only two free passes, he threw just 49 of 84 pitches for strikes. The right-hander also tied a season low with one punchout, though he notched a solid 13 whiffs. This was far from Kochanowicz's best outing, but on the plus side he avoided giving up a homer for the first time in his past five starts. Kochanowicz has managed to hold onto a role at the back of the Angels' rotation despite posting a mediocre 5.49 ERA through 16 starts, and he's tentatively slated to face the Nationals the next time he takes the mound.

Latest Fantasy Rumors
Secure in rotation?
PLos Angeles Angels
June 12, 2025
Manager Ron Washington said Sunday that there's been no conversations about removing Kochanowicz from the starting rotation, reports Sam Blum of The Athletic.
ANALYSIS
That hardly means the right-hander's rotation spot is secure, but the Angels aren't entertaining a role change yet, at least publicly. Kochanowicz made his MLB debut last season and had a 3.99 ERA, 1.19 WHIP and 25:10 K:BB across 65.1 innings, but he's struggled to a 5.61 ERA and 1.63 WHIP through 13 starts in 2025. He's given up exactly four runs in each of his past four outings, and Kochanowicz may need to turn the corner soon in order to stick in the rotation.
