I wish I had good news about the Phillies to kick off the Crash Bag with this week, but the team is bad. Well other than Aaron Altherr and Tommy Joseph who are #3 and #1 respectively in wRC+ for the month of May.
For now the best place to ask questions is on Twitter, either @ me (@Matt_Winkelman or @CrashburnAlley). But you can also reply in the comments here and I will will have some sort of better way for future mailbags.
@JPallo26: What are your go-to statistic/analytic/breakdown sites and what do each do particularly well in transferring good info?
This is a great question because it really made me think about what sites I use and why I use it.
- Baseball Reference – This is still the gold standard, especially after their re-skin. The Play Index continues to be the most powerful research and search tool. I love that on both the minor and major league level that you can highlight a set of games in the game log and get the stats over that time. Their splits pages are also much more robust than anything offered by another site.
- Fangraphs – This is my quick and easy stats site. They have BB%, K%, and batted ball data in a place that is very easy to grab. The percentage stats are just a lot more informative and intuitive to me than the per 9 stats that Baseball Reference uses. The new Splits Tool is very good, and I have not had as much time to really play with it as much as I would like to. They also just added minor league batted ball data.
- BrooksBaseball – I trust their velocity and zone measurements more than anyone on the internet. If I’m writing something major league pitching related, there is a high chance I opened up Brooksbaseball at some point (this includes hitters vs pitchers).
- Baseball Prospectus – I like their prospect stuff, but on the statistical side they are doing the most cutting edge research. DRA is the best ERA estimator we have, and it really allows you to think about all of the factors that go into a pitcher’s success. I am still trying to wrap my head around all of the value and long term implications of their framing and pitch tunneling data, but it is research no one else is doing.
- MLBFarm – This is Daren Willman’s essentially defunct minor league site, but it gives you minor league spray charts that you can customize over date ranges.
- MILB Stat Pages – They aren’t fancy, but they update faster than any other site and have basic splits. The MILB pages alse have the most accurate transaction logs.
- Baseball Savant – There is a lot of statcast data here that I don’t really trust and I don’t think is delivered in a way that makes it easy to do your own analysis on. However, their searches are good if you want to really dive into pitch location and usage.
- Baseball America – Not really statistical, but if you have a subscription there is a ton of archival information on players. Also it normally has the demographic information that you won’t always find everywhere else.
