2021 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. The result is a document that rivals The Power Broker for length, though we’ve endeavored to make it more easily digestible. If you happen to have missed any of those installments, you can use the handy 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 now. Teams aren’t static. Since we’ve published our rankings, Eloy Jiménez ruptured his left pectoral tendon and underwent surgery; Luke Voit will miss time with a partial meniscus tear. The Angels reworked their bullpen on Monday. The Rangers announced that Rougned Odor won’t make the Opening Day roster and will be designated for assignment. Players will tweak elbows and hamstrings, lose playing time due 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. Don’t be alarmed: The WAR numbers you see there may vary from what you see 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 include later use the WAR from the Team WAR Totals page as well. It’s a valuable resource I recommend bookmarking. Read the rest of this entry »
