2025 Fantasy Outlook
For the second straight year, Kirby had the lowest walk rate among qualified starters at 3.0%. He got off to a rocky start with an eight-run blowup in his second outing of the year and a 4.33 ERA through his first 11 starts. However, Kirby then turned in nine consecutive quality starts from June 9 to July 26. Water usually finds its level, and Kirby's 3.53 ERA at the end of the year was pretty much right in line with the underlying skills (3.58 xFIP, 3.56 SIERA). He's now reached 190 innings in back-to-back seasons and is a huge piece of the best rotation in baseball. The only problem is that Kirby still has not shown any growth with his strikeout rate, which has hovered right around 23 percent in each of his three seasons in the majors so far. It's not out of the question that the right pitch-mix tweak could unlock another level with the punchouts, but that's purely conjecture. Expecting that at this point requires a leap of faith.
