Pitcher Playing Time Changes: April 4, 2025

Welcome to the first Pitcher Playing Time Changes rundown of the regular season! As with position players, the methodology is a little different in the regular season.
For starting pitchers, instead of displaying raw games started projections like I did during Spring Training, I’m switching to percentage of a team’s remaining starts. When looking at this on a weekly basis, pitchers who are closer to coming back from injury will have their percentage go up, since they’re projected to miss less of the remaining season. Pitchers who were injured since the last update will, of course, have their percentage go down.
Relievers are going to be more streamlined, in that I’m not going to actually show projected innings pitched, because the way we project them internally always show as full-season innings, even if there’s only 50% of the season left. For example, a relief pitcher who started with 70 projected innings pitched and had his projections unchanged will still show as 70 innings pitched after 81 games. So, instead, I’ll just be showing percent change for notable relievers and we won’t be focusing on the actual innings they’re projected for when we’re only talking about a week of difference. That allows me to zero in on pitchers who’ve gotten injured or demoted.
Away we go:
