I’m Clay Davenport, one of the founders of Baseball Prospectus. I still have a (looser than before) affiliation with BP, so don’t expect to see me using this site to dish dirt or run anybody into the ground. I’m old enough and stubborn enough to have my own way of doing things, and some of those things are contrary to the way BP wants to do things, which is why I wound up out here.
The main products for me – judging by the way I find myself accessing the site when away from home – are the DTs by Organization pages. DT stands for Davenport Translations, and they are a system I’ve developed over 20 years to translate statistics from one league into another. Given a player’s known performance in one league, they estimate what that performance would be worth in another league. The two main uses I’ve made of that are translating stats from past major league history to different eras – what Babe Ruth, for instance, might hit if he were playing today.
The DT pages now are more than just DTs. They are a linked set of over 2000 pages based on four permutations in the menus at the top of each page. You can choose from each of 30 major league organizations, switch between hitter and pitcher stats, choose between three levels of translation (real untranslated stats, normal translations, and peak translations, which extrapolates a player’s peak performance from his current stats). The fourth menu consists of a variety of split choices, so you can use these pages (in REAL form) as a source of minor league splits. Or you can see that, while a player’s overall stats don’t translate to major league value, his performance against LH players might.
The DTs by league are just the same as the DTs by organization, but arranged by league. Both the league and org DTs will eventually be available for years prior to 2011, and will have player pages.
The EQA page gives you a current look at the Equivalent Average and related stats for every player in major league history, with breakdowns by team and position. Links through the EQA page connect you to a stats page for every player in major league history, just as I’ve had on BP for years. One difference is that I have broken the player pages into sub-pages, for hitting, pitching, fielding, and – at least for the last 30 years – the full minor league DT that goes with them. So you can see what kind of player Derek Jeter was expected to be from his minor league numbers.
