Fielding Effects

Through games of Thursday, 8 June 2023.
All results are from true, unadjusted data.

The Table shows two lines for each team. The first is their actual stats to date, from Games through Strikeouts; the stats FEbat and FErun—Fielding Efficiency on batters and Fielding Efficiency on runners—are explained on our page here about Team Fielding. The OR stat on this line is the TPP-projected Runs the team would be expected to have yielded to date (for an explanation of the TPP, see our page here about basic Baseball Analysis). The R stat is the TOP-projected team Runs scored to date. The Δ stats are immaterial for this line.

The second Table line for each team is their calculated stats if their defense were MLB-average. The FEbat and FErun values on this line are their MLB-average values (averaged over the three recent years 2017 - 2019). The OR stat on this line is the TPP-projected Runs the team would be expected to have yielded to date based on the average-fielding stat values. And on this line, the Δ stats show the differences in Wins that having an MLB-average defense would gain or lose (the ΔW stat is for the year to date, while the ΔWyr is for a full 162-game season.

Thus, this table shows us what a given team’s defense is doing to help or hurt it. As you see, the average difference is less than 3 wins a season, and that figure is heavily weighted by a very few very bad defenses. (Without the three exceptionally worst, the average difference is just 2 wins a year, and the widest swings from assuming an MLB-average defense are 6 lost by good-fielding teams and gained by poor-fielding teams, with 2/3 of the teams within a couple of wins of average-fielding results.

(Those interested in the tiresome details of the calculations can follow that link to a full explanation.)

We cannot easily disentangle pitching from fielding, because fielding affects pitching results. But, painting with a very broad brush, we can say that at the extremes the fielding-attributable difference in runs allowed is in the range of being equivalent to perhaps a quarter to a third of a run on the team ERA, with the more normal variations amounting to about an eighth of a run. Pretty clearly, on a team level, fielding runs a poor second to pitching in significance for runs allowed, and thus a very poor third to offense. (Recall that offense and defense are each 50% of the game, and defense is part pitching and part fielding.) Since the extremes of team ERA cover about 2.75 runs (in 2020, 3.02 to 5.75) while the extremes of fielding, even including all the outliers, equate to maybe 0.60 on an ERA, their ratio is—and again, this is very, very broad-brush thinking—around 9:2, making fielding perhaps at most around 20% of defense and thus pitching about 80%, meaning that offense is 50% of the game, pitching is 40%, and fielding is at most around 10%, and so of much less importance than either offense or pitching. (Quite as we said almost 40 years ago.)
