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.
Free agent reliever Sean Burnett signed a minor-league pact with the Marlins on Saturday. Per MLB.com’s Joe Frisaro, the left-hander is slated to begin the season in extended spring training and will work toward a role in the majors.
Burnett, 35, has not appeared in full-time role in MLB since 2012. He last pitched for a big league team in 2016, surfacing for 5 2/3 innings with the Nationals before returning to the minors. Despite signing a minor-league deal with the Phillies last spring, he failed to make the Opening Day roster and was released prior to the start of the season.
Complicating Burnett’s return is a slew of chronic elbow issues. The left-hander has dealt with everything from bone spurs to a torn UCL over the last six years, and will need to take things slowly in the minors before the Marlins consider adding him to the bullpen this season.
