Hello there, you may not be familiar with my series preview breakdowns. I did these, in evolving formats, for years at Lookout Landing and I hope to continue doing them here. I’ll do so even if only for my own benefit since the above and below charts are informative for me and I like to get the periodic checks on how the composite units of the Mariners are doing.
Since this may be new to you, I’ll run through what each row means. Hitting is judged on each team’s park-adjusted wOBA to date. I’m using the wOBA from my site, StatCorner.com, so that answers any questions on why it might be slightly different than FanGraphs.com or whatever your preferred site shows.
xRA is laid out in a really long post here, but the simple take is that it’s xFIP meets tRA. That is, it’s xFIP plus batted ball types and whether or not the batted balls were pulled or hit the other way.
|INFIELD||3.4 (2nd)||5.3 (1st)||White Sox|
|OUTFIELD||-0.4 (15th)||-4.3 (26th)||Mariners|
|RBBIP||0.245 (8th)||0.263 (10th)||Mariners|
|OVERALL||3.0 (7th)||1.0 (9th)||MARINERS|
Fielding is judged by looking at how often each team allows a ball in play to result in a runner on base via either a hit or error. There’s more explanation available, but the 10,000-foot view is to take all the balls in play, adjust them for the park (yes, it has an effect), and then for each type (e.g. grounder, liner), figure out how often they should turn into outs and the cost (in run value) of not turning them into an out. Then add it all up. It can’t be used to judge individual defenders, but I’m not convinced of any metrics’ worth at doing that anyways.
Above, I split the fielding into infield and outfield units based on who I judge is responsible for fielding each batted ball type. Unremarkably, the Mariners are already showing a divergence between their infield defenders and their outfielders.
