Now that the 2022 MLB playoffs are underway, it's time for a postseason-flavored update to my in-season ace rankings.
This is a look at players on teams in this year's playoff and only those currently healthy or projected to be healthy very soon. Instead of projecting for the next season, a potential peak season or a full career, this ranking is based on value for this postseason alone, not considering how deep their teams might go. Here's last year's playoff list and this year's April list.
That means past postseason experience counts more than in a conventional ace ranking (and in many cases will act as a tiebreaker), while 2022 performance is more relevant than a multiseason track record, though having both is even better.
