Simon - Why Does Bryce Harper Have -25 Defensive Runs Saved?

Sounded some warnings about Bryce Harper’s defense in April. Here’s a revisit as the season nears an end. He’s at -25 Defensive Runs Saved, among the worst totals in MLB this season.


Jordan @metsfansince02
Do you think a move to first base next season is possible? I heard he was taking a lot of grounders there this year.

Mark Simon @MarkASimonSays
I think the money is in the outfield. The move to 1B comes later.

Fangraphs: Jackie Bradley, Jr. and the Error Rule

To summarize:

1. The MLB rules state that the part of the error rule about ordinary effort is an objective standard.

2. The part of the error rule that says it’s all dependent on the judgment of the official scorer establishes a subjective standard.

3. Statcast is more 1. than 2.

IMO the standard of “ordinary effort” applies to any part of the fielding process, not the sum total. If a fielder gets an extraordinary jump, runs with extraordinary speed on an unusually efficient route, and then botches the catch, it doesn’t matter that ordinary effort wouldn’t have put him in position to make the catch. A fielder in position to make the catch will, in ordinary effort, make the catch. Failing to catch it, after getting into position, is an error. Failing to get into position to make the catch - through ordinary effort - is not an error.

Jeff Passan on Twitter: “1) I totally buy the idea that players can bring significant value via defense. 2) I have not seen every Cubs game this year, so maybe I’m missing something. 3) I stand by my years-old contention that publicly available defen

When you find a metric which surprises you, it’s best to dig into the data a little before you say something silly. Anway, and I know this is an outlier, the entire ?thread? is worth reading.
