Michael King Has Assumed His Right Place as a Starting Pitcher

Where is the line that tells you whether a pitcher is a starter or reliever? It’s subjective, but there are a few benchmarks that baseball folks have used over time to determine a pitcher’s role. Do they have more than two pitches? Do they have extreme splits? Does their velocity hold as their pitch count increases? Depending on the answer to any of these questions (and more), you’ll have a decent idea of a pitcher’s fate as a starter or reliever.
Sometimes, though, pitchers get moved to the bullpen simply because the other five options at any given time seem more viable, and not necessarily because they didn’t possess the skills to dish out six quality innings. The latter firmly describes Michael King.
King was a starter throughout his entire minor league career and even started a few games during his debut season in 2020 before settling into a long relief role in 2021 thanks to a crowded Yankees rotation. But the version of King we saw in the minors and those two seasons is not what he is now. For that, we have to reference his 2022 season, when he fully embraced his ability to supinate and started throwing his sweeper as his only breaking ball, upping the usage to 30%; the year prior, he only threw it 10% of the time. Before suffering a season-ending elbow fracture, he posted a 2.29 ERA and 2.23 FIP in 51 innings, delivering several multi-inning outings out of the bullpen.
On top of his sinker and sweeper, King displayed his ability to mix in his four-seamer and changeup at the right times, both of which have been crucial to his success as a starter; more on that later. That gave him a four-pitch mix where each pitch was at least average and more than one that was plus. That’s the exact kind of arsenal you’d expect a rotation arm to have, but coming off elbow surgery and bullpen success and facing another full starting five, the expectation wasn’t that he’d get the chance to pitch in that role.
