Baseball Prospectus News
Reintroducing PECOTA, the Depth Charts, PFM, and DraftAid
Pitchers and catchers have yet to report to spring training, and the Seahawks are still celebrating, but the PECOTA projections are here, earlier than usual.
(We interrupt this announcement to bring you the direct link to this year's PECOTA weighted-means spreadsheet.)
In order to access the PECOTA forecasts, you need to be a Premium (or soon-to-be-available Super-Premium) subscriber to Baseball Prospectus. Monthly subscribers will have access to certain PECOTA features but will not have access to downloads like the PECOTA spreadsheets. The best value we offer is a yearly subscription, which not only gives you access to the full PECOTA product offering, but also unrestricted access to our website's extensive baseball coverage.
In the 11 years since the first "Introducing PECOTA" article in Baseball Prospectus 2003, PECOTA has proven to be one of the best predictive systems in the industry. The current edition was the brainchild of Colin Wyers, who was hired by the Houston Astros as this winter's work took place. Colin's core concept of having the batter-pitcher matchup quantification center around batter TAv and pitcher Fair RA remained untouched, and the annual weights that Colin explained in detail back in 2012 remain intact. Without his work, PECOTA wouldn't have been possible this season, and Baseball Prospectus' loss is the Astros' gain.
This does not mean that innovation and improvement have stopped—several improvements took place, with the most visible example being that minor-league players will now appear in the comparables lists, though only if they subsequently went on to have major-league careers.
Our playing time estimates are based on the input of the Baseball Prospectus staff and coordinated by Tim Collins. Keep in mind that these aren't etched in stone: pitchers and catchers still haven’t reported to camp, and some key free agents still haven’t signed. We will be updating these playing time estimates frequently as teams make moves and we see how rosters shape up in advance of Opening Day.
One other note: players who aren't projected to play in 2014 have hypothetical projections that can be seen atop the player cards, with fictional playing time numbers. This fiction is based on actual playing time from past seasons (with MLB playing time much more highly weighted) or a minimum of 250 PA for hitters or about 33 IP or more for pitchers, depending on role. As an example, here's Matt Harvey, who had 59 and 178 MLB IP the past two seasons, respectively (and a lot more MiLB IP in 2012):
Of course, we don't think Harvey will actually pitch nearly 150 innings in 2014. We know he's hurt, which is why the Mets Depth Chart doesn't include him. This is a "what if" scenario that should give an idea of what he could have accomplished (in even more innings) if he'd been healthy.
Right now, we’re rolling out the following:
