An in-depth look at team defense throughout baseball history

8 Comments

Evaluating defense in baseball continues to be a work in progress. We’re way better off than we were even a few short years ago, but it remains a tricky and often subjective undertaking, with most people not being able to say much more about the topic apart from “that guy plays good defense” and “that guy is a liability.”

Against that backdrop, Baseball Crank spent an enormous — and I mean a really, really enormous — amount of time analyzing team defense between 1871 and the present, focusing primarily on Defensive Efficiency Rating. It’s in two parts: here’s part 1 and here’s part 2.  There are stats, but it’s not too hard core, and Crank does a good job of explaining what he’s talking about as he goes along.

Great stuff if it’s a topic that jazzes you.

The Tigers announced on Wednesday evening that the club and shortstop Jose Iglesias agreed on a contract for the 2018 season, avoiding arbitration. Anthony Fenech of the Detroit Free Press reports that it’s a one-year deal worth $6.275 million.

Iglesias, 28, was eligible for arbitration for the third and final time, which means he can become a free agent after the upcoming season. This past season, he hit a light .255/.288/.369 in 489 plate appearances. However, both defensive metrics and scouts paint him as an above-average defender at shortstop.

The rebuilding Tigers are still reportedly trying to trade Iglesias. The club already traded veteran second baseman Ian Kinsler this offseason. During last season, the Tigers moved J.D. Martinez, Alex Avila, Justin Upton, and Justin Verlander.
