As promised, our prospect coverage takes a big step forward.

It’s been almost three months since a cryptic instant message from Kevin Goldstein appeared on my screen: “Just had a weird thing this afternoon.” That was my first indication that we might have some remodeling to do. Fortunately, we had a capable successor in place, and once we knew we had to make changes, Jason Parks’ presence made the transition smooth. Our first priority has been to keep the content you’re used to coming: Bradley Ankrom has adopted (and added to) the Minor League Update, Hudson Belinsky has covered The Call-Up, and Jason has coordinated a tag-team approach to the Monday Morning Ten Pack while beginning his preparations for the prospect rankings process.

Now that we’ve solidified the staples, we can expand and experiment. Over the past few weeks, Jason, Joe Hamrahi, and I have drawn upon our own experience and the input of others to put together a bigger prospect staff than we've had at any point in BP's past. The talented team we're introducing today will allow us to increase the volume of our prospect coverage without compromising its quality. We know you still want to see the same stuff we’ve been doing, and we’ll be bringing you even more of it. But we’ll also be branching out. The additional voices in the room will give us the freedom to try a whole host of new things, from frequent scout quote collections to roundtable discussions and prospect debates to information on levels of competition and aspects of the player development process that BP has barely delved into. We hope you’ll enjoy joining us on this journey, and we’ll welcome your feedback along the way.

Want to know not just what pitches a pitcher throws, but where, when, and in what order he throws them? Now you can.

At Brooks Baseball, we’ve built a repository where you can access almost any information about any pitcher’s pitches and be confident that the pitch types were identified correctly. For example, you can ask how many times batters swung and missed at a Stephen Strasburg changeup, how often batters hit Chris Sale’s slider for a groundball, or what the overall called-strike rate is for Felix Hernandez’s fastball.

But PITCHf/x databasing is still in its infancy. Pitching is not the sum of individual statistics about individual pitches any more than a piece of music is the sum of an individual set of notes. Pitching is a sequence of events—the previous pitch’s execution may be as germane to the outcome of the at-bat as the current pitch’s execution. We often hear about how a pitcher might go up in the zone with a high fastball to raise a batter’s eye level and then down in the zone with a curveball. None of that was captured in the maze of tables and charts already available.

BP's prospect coverage is about to take on a new look for 2013, and Jason is excited to be a big part of it.

We welcome change when it brings about good fortune, or new hope, or bad Scorpions songs, but the fear associated with the unknown aspects of change can paralyze your progress and limit your desire to accept a new reality. At Baseball Prospectus, we are walking into a new tomorrow without our most prominent and respected figure, a baseball mind of such merit that the major leagues finally purchased his contract and called him up to the active roster. In uncertain times, the drug of choice is certitude, and I’ve been bird-dogging the streets for dealers and distributors. How do you replace a seasoned veteran of national prominence over a weekend?

I haven’t been in the prospect game as long as Kevin, and I can’t stand next to his resume at this stage of my career and pretend we are equals. I was casually writing for a team-specific blog when Kevin and I became friends, and this is after I spent years reading his work and impersonating his pomp on various platforms. We were friends before we were co-workers, and we were co-workers only because we were friends and he thought I’d make a good podcast partner. Can you imagine the brain trust at Baseball Prospectus after that request was made? I didn’t have a footprint on Twitter. The “industry” didn’t know my name. I had developed solid contacts, but mostly on the [Texas] Rangers side of the coin, and even though I felt some degree of confidence in my scouting knowledge, my world was so small that any standing was significant. Kevin fished me out of a small pond and relocated me into the national waters of Baseball Prospectus. He’s my Robert Shaw.

Kevin takes on an exciting new challenge: working for a big-league front office.

This one isn't easy. I don't even know where to start. I remember some editor yelling at some writer in some movie about not burying the lead, so I'll do that. This is my final piece at Baseball Prospectus, as I've accepted a position as Pro Scouting Coordinator for the Houston Astros. That doesn't sound real to me yet either, but there it is. Needless to say, I'm extremely excited about this opportunity and the challenge ahead of us. I've been nothing but incredibly impressed with the entire staff in Houston, as well as their plans for the future, and I'm absolutely honored to suddenly be a small part of it.

Yes, it's a dream job, no question, but this wasn't an easy decision. I love this place. Honestly and truly. In my six-plus years here, I've grown personally and professionally and was never asked to be anything but myself. You really can't ask for anything more from a place of work. I've seen a lot of changes since I was brought in by Nate Silver, and I can't tell you how excited I am for the future under Joe Hamrahi. There are many fantastic things happening at Baseball Prospectus, and so many more things coming because of Joe's leadership. Knowing the ship has such a fantastic captain at the wheel made this decision much easier, as does the content published here that continues to blow me away on a daily basis. People like Ben Lindbergh, Sam Miller, Colin Wyers and Bradley Ankrom are going to be huge in this world, and I can't wait to see it happen. And prospect coverage won't be any less comprehensive here, either. You should expect some exciting announcements in that regard, and soon.

A few days after the rollout of the BP Hitter Profiles, we present their companion piece, the Pitcher Profiles.

Last weekend we posted “Hitter Profiles,” which let you look at PITCHf/x data for each hitter in MLB filtered by a bunch of different attributes. Today, we’re posting their companion piece, “Pitcher Profiles.” You can search for pitchers here. As we did for the Hitter Profiles, we’ll be adding a dropdown link to the search interface from the “Statistics” tab on the nav bar at the top of the page.

We think these profiles will revolutionize the way people look at PITCHf/x data. Location is perhaps the most important attribute of a pitch, and the Pitcher Profiles allow you to examine the results of pitches across multiple spatial locations. PITCHf/x data has been available for five years, but we haven’t been able to examine it this way, at least publicly. (There are scouting services that provide this kind of data.) It was the first thing that a scout I talked to asked for.

We roll out a new feature designed to help you dig deeper into how pitchers approach hitters and how hitters respond.

While reading message boards, sabermetric websites, or newspapers, you’ll often come across contentions like, “So and so is a good low-ball hitter.” While listening to the radio, you’ll be told that a player swings and misses a lot at pitches down and in. Or you might wonder: What’s the cause of a hitter’s dramatic change in performance from season to season? Is it something different about his approach? Is he less effective at getting to pitches in certain parts of the strike zone?

We’re here to help you answer those questions. Today, we’re rolling out a “beta” version of our PITCHf/x-driven Hitter Profiles. Essentially, they create sortable hot/cold zones for every hitter in “the PITCHf/x era” (2007-12). You can sort by AVG, SLG, the BP all-in-one offensive statistic TAv, Swings, Whiffs, and various types of balls in play. You can investigate where and how pitchers have attacked a hitter to see if that’s changed. You can sort by month or by year. You can do platoon splits. And you can switch between any of the pitches identified in the custom-classified Pitch Info LLC database that is also featured in our Pitcher Cards.

We catch and correct an error in our playoff odds.

We’ve identified incorrect data in the playoff odds report. The purpose of this post is to explain what happened, announce that it’s fixed, and offer some technical notes on the process so readers can reassure themselves that it’s now working as it should.

At the heart of the playoff odds report is a database table that contains the current-season MLB schedule. We use that table for many other products as well. After the season started, we moved many of the other products to a different schedule table that went back through the entire Retrosheet era and also included additional data. The playoff odds were a straggler, because we were working on a project that would allow us to run them for previous seasons. (The adjusted standings have been similarly modified, and soon we’ll have adjusted standings available back through 1974 on the site.) So the changes were made to the new playoff odds codebase, and the old codebase was left running on the old schedule table. Unfortunately, at some point during the season, the old schedule table stopped updating properly.

We've cleaned out the clutter and updated our definitions, so it's now easier than ever to understand us.

Navigating the Baseball Prospectus Glossary has been an occasionally frustrating, often-unfulfilling proposition in recent years. Kurt Vonnegut had it right in Hocus Pocus when he wrote, “[Everybody] wants to build and nobody wants to do maintenance.” For some time now, we’ve been adding to and subtracting from our statistical suite without being as diligent as we should have about updating and cleaning out the clutter in our glossary section. But that’s all behind us. We’ve spent the past month revamping the glossary, and now it’s ready for a big reveal.

Those of you who have used the glossary before will notice a new structure. In the past, the glossary featured over 20 categories. We wanted to streamline the browsing process, and we made reducing the number of categories (to 14) our top priority. Offering near-identical categories that differed almost solely in name only complicated matters, so we trimmed the extraneous ones without sacrificing any useful information. Here are the categories we’ve decided to present, along with a brief summary of each section’s subject matter:

New, daily editions of the Hit List, Collateral Damage, and What You Need to Know will combine vital information in one convenient package throughout the season.

Things at BP have never been busier. We hope you’re enjoying the increased content on the site these days and that your workplace productivity has suffered accordingly. We also hope you enjoy setting aside some time to dig into our in-depth opinions and analysis. However, we know not all of you have hours to read about baseball every morning, and we still want to give you a way to digest the day’s most important developments quickly.

That’s where our new daily content comes in. We initiated this change last Friday; we’ll now be running three new or reworked columns every morning from Monday through Friday: the “Daily Hit List,” “What You Need to Know,” and “Collateral Damage Daily.” Below, you’ll find descriptions of what you can expect from each one.

We've been busy since our last State of the Prospectus, so it's time to bring you up to date on all of the exciting additions to our roster.

Steven Goldman wrote something in his preface to Baseball Prospectus 2011 that has stuck with me since. I quoted it in my own preface to the Best Of Baseball Prospectus books, and I’m about to quote it again. Someday, I’ll feel inspired and find another line to use in my introductions. For now, though, Steven’s sentiments will suffice, since they explain how we’ve managed to remain true to our roots even as many of our founding members and longtime contributors have moved on to other challenges.

True institutions do not survive due to the efforts of any one or two people, but because a collective of believers holds true to their animating principle, thus forming an unbroken chain from founders to inheritors. In our case, we continue to focus on cutting through baseball’s homilies—stomping the dead, whenever possible, along the way—in favor of realism and hard truths.
