2023 Positional Power Rankings: Summary

Over the past week and a half, we’ve published our annual season preview, ranking the league’s players by position and team based on a blend of our projections (a 50/50 split between ZiPS and Steamer) and our manually maintained playing time estimates courtesy of Jason Martinez. If you happen to have missed any of those installments, you can use the navigation widget above to catch up.
Today, I’m going to summarize the results. We’ll look at some tables and pick out a few interesting tidbits in a moment, but first, it’s important to remember that this exercise captures a snapshot of how we project teams to perform right now. Teams aren’t static. Since we began publishing our rankings, prospects Anthony Volpe, Jordan Walker, and Brice Turang all made their respective clubs’ Opening Day rosters, and Grayson Rodriguez and Brett Baty learned they will have to wait a little while longer. The Brewers designated Keston Hiura for assignment (he has since cleared waivers and been outrighted to the Brewers’ Triple-A team) and signed non-roster invitee Luke Voit to a one-year big league deal. Rhys Hoskins tore his ACL and will likely miss the season; Triston McKenzie injured his shoulder and could miss up to eight weeks.
This being baseball, players will tweak elbows and hamstrings, lose playing time to underperformance, and get traded. That’s why we maintain a Team WAR Totals page, which lists projected positional WAR by team and updates regularly throughout the season as we learn more about who is likely to take the field every day and what shape they’ll be in when they do. It’s important to note that the WAR numbers you see on that page may differ from those you’ve seen on the positional power rankings, mostly because those figures are aware of the injuries and transactions that have altered our playing time estimates since the rankings went live; the Z-Scores I’ll include later also use the WAR figures that power the Team WAR Totals page.
