Our new normalization option lets you compare hitters and pitchers to players of the same handedness.
First, thanks for your enormous level of support and feedback for our new Hitter and Pitcher Profiles. Because of your suggestions, we increased the number of sortable statistics to 19, added several new color schemes, changed some of the layout, and added several new multi-sort options. Your feedback makes building new and great tools easier, so thanks!
We want to announce a new option on our tools and briefly describe how it works. This option is “normalization,” which allows you to compare a pitcher or hitter to other similar pitchers or hitters. It works only for a few of the 19 sorts right now—it will work for all of them eventually—but we think that the most instructive sort is “frequency,” so we’ll describe it using that and let you play around with it. We’ve already done some limited “beta testing” of this new feature via Twitter, and people found it really fun and informative, so we’re excited to announce it on Baseball Prospectus. (As an aside, Harry and I often beta new features late at night on Twitter, so you can come follow us and be part of the creative process if you want.)
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.
A review of the most productive bats in all of the full-season minor leagues.
For too long, it's been one of the hidden gems on our website. I'm guessing many readers had no idea that we have minor league stats, including Davenport Translations and the usual BP metrics. It's a wonderful tool for looking at the numbers and getting some balance, and to celebrate their more prominent new position on our statistics home page, let's hand out some hardware with some BP Hitter of the Month awards using our own metric, Equivalent Runs.
Popping the hood on King Felix as a demonstration of what's possible with PITCHf/x data
"Hell, yeah, I want to throw that pitch. They don't let me, though. They tell me I'm too young, that it's bad for my elbow. I told them I want to throw it."
--Felix Hernandeztalking about his slider before the 2006 season
Is pinch hitting good or bad? Guest writer Andy Dolphin uses the 2005 Phillies as a point of departure and takes a closer look.
A strong bench would seem to be one of those indispensable elements of a successful team. After all, if you need to generate some offense late in a game, you need players on the bench you can count on. (Not to mention, of course, the need to give players a break and have replacements for injuries. For this article I'm just looking at pinch hitting.)
The 2005 Phillies seemed to have just what they needed, in the form of four quality outfielders: Bobby Abreu (.286/.405/.474) in right, Pat Burrell (.281/.389/.504) in left, and Kenny Lofton (.335/.392/.420) and Jason Michaels (.304/.399/.415) sharing time in center. This must have been a manager's dream, right? Lofton or Michaels on the bench, able to come in and get on base to keep a rally going? Let's see how it worked out.
