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.

Hit hard in loss
PLos Angeles Angels
May 5, 2025
Kochanowicz (1-5) took the loss Sunday against the Tigers, allowing five runs on seven hits and two walks while striking out a batter in five innings.
ANALYSIS
Kochanowicz's troublesome innings came during the second and third when he let up all five of his runs. A pair of walks to begin the second was a recipe for disaster, as the Tigers took advantage and scored three runs. Colt Keith made it four straight starts with allowing a home run with a two-run blast in the third. It's been brutal for Kochanowicz thus far, as he ranks bottom five among qualifying pitchers in ERA (5.79), WHIP (1.50) and strikeout rate (12.3%) among other categories. He'll aim to rebound in a home start versus Baltimore over the weekend.
