Park Factor Review: A Look at All Parks, Majors to A-Ball

by Clay Davenport

Now that we've gotten to the 100-game mark on the season, I decided to take a look at how the park factors were shaking out so far in '04. Park factors are noisy pieces of data--that's the reason why we use three-year averages in the first place--and I expect that some of these 100-game factors will change significantly between now and the end of the season. That caveat aside, let's take a look at how pro baseball's parks--from the majors down to A-ball--are playing.

Making Changes: A New Look at Minor League EqA

by Clay Davenport

As some of you may have noticed, there have been some changes in the Minor League EqA page. Let's start with the simple. When you go there now, you'll get a short, simple, fast download, with what is essentially a page of links. The long list of every player in the minors? Not gone, but moved under its own link--so that only the people who really want it have to wait for it to download. The main feature on the page is a list of all the leagues, along with their stats, sorted by offensive level. I'm always trying to remind people of the context of minor league statistics, and this is one more heavy-handed way to remind people that some leagues (near the top) favor the hitters, while others (near the bottom) favor the pitchers. Click on the league, and you'll get the information that was on the old minor league page: a top-10 list for each league, a breakdown of league statistics by position (approximated by games played at each position), and a list of all players in that league, sorted by team.

Baseball Prospectus Basics: About EqA

by Clay Davenport

Dayn Perry explained why various statistics--like batting average (AVG) and runs batted in (RBI)--were not as reliable as you've always been told, and why we at Baseball Prospectus don't use them in our analysis terribly often. Today, we're going to look into one of the statistics we do use: Equivalent Average, or EqA. In its rawest state, EqA is a simple combination of batting numbers, not so very different from OPS. Compared to OPS, it counts walks and HBP a little higher (at 1.5 instead of 1), it has stolen bases, and hits and extra bases are counted a little less (since they are divided by plate appearances, not just walks). What, then, makes EqA different from the other statistics? Simply put, its more accurate, its unbiased, and it models the scale of batting average, so it's easy for a new fan understand.

Winter and Fall League Translations: Just How Good Are These Leagues, Anyway?

by Clay Davenport

The regular seasons for the various winter leagues are over now, although the various league playoffs leading to the Caribbean World Series are still ongoing--a process that runs almost as long as their regular season, kind of like the NBA. The Caribbean World Series is a contest between the winners of the four regional leagues: the Dominican, Puerto Rican, and Venezuelan winter leagues, plus the Mexican Pacific League. What I'm going to do here is to give an overview of those four leagues, plus the Arizona Fall League, with an emphasis on how to make sense of winter league statistics. The process for working out the talent level of a league depends on, number one, having a large number of players in the circuit who have played in other leagues; and number two, knowledge of how good those other leagues are. Every player who has played here and elsewhere becomes a data point: You rate the player's hitting (or pitching) level, relative to league average, with park adjustments when you have them, in both leagues. If his relative offensive level gets worse, that is a (slight) argument that the new league is tougher than the old. If it gets better, that's an argument that the new league was easier.

Premium Article Dodgers Tap Henderson: They Didn't Lose Rickey's Number

by Chaim Bloom and Clay Davenport

Rickey's back. The Dodgers are 49-44, three and a half games out of the Wild Card, but if their pitching were as bad as their offense they'd be the worst team in the majors. Paul Lo Duca (.307/.374/.438, .285 EqA) is having a good year, but when the All-Star catcher looks out at the rest of his team, he sees an offensive wasteland. At first base, Fred McGriff (.249/.318/.430, .261 EqA) was unimpressive before going on the DL. Up the middle, Alex Cora (.240/.281/.319, .213 EqA) and Cesar Izturis (.255/.290/.302, .210 EqA), who have gotten most of the playing time, are a combined black hole. Third baseman Adrian Beltre (.225/.286/.356, .227 EqA) has seen his star come crashing to earth after having once been one of the hottest prospects in the game. In the outfield, Shawn Green (.255/.317/.429, .262 EqA) is underachieving, and none of the combination of Mike Kinkade, Dave Roberts, Jolbert Cabrera, Chad Hermansen and Wilkin Ruan has been exceptional. Brian Jordan (.299/.372/.420, .282 EqA) had been the bets of the bunch, but a severe injury means his season and Dodger career are over. Faced with the option of buying or selling for the stretch run, the Dodgers made their move, trading for Jeromy Burnitz and plucking Rickey Henderson from Newark.
