Below are some definitions for some statistics that I will refer to over the next couple of posts (and most future posts).  I’m going to assume that everyone is familiar with more traditional statistics such as OBP, SLG, ERA, etc, but not necessarily familiar with some of the newer sabermetric statistics that both of my grandfathers would probably hate (my Dad may even hate them as well…I’ll ask him and provide an update at a future time).  All of these definitions are taken directly from Fangraphs, and if you would like to investigate them further, head over to the Fangraphs library page for more detailed explanations, as well as how these statistics are calculated.

BABIP (Batting Average in Balls in Play)Batting Average on Balls in Play measures how many of a batter’s balls in play go for hits.  Typically around 30% of all balls in play fall for hits.  There are three main variables that can affect BABIP rates for individual players: Defense, Luck, and Changes in Talent Level.

wOBA (weighted On Base Average) – Weighted On-Base Average combines all the different aspects of hitting into one metric, weighting each of them in proportion to their actual run value. While batting average, on-base percentage, and slugging percentage fall short in accuracy and scope, wOBA measures and captures offensive value more accurately and comprehensively.  It is set to the same scale as OBP, so league-average wOBA in a given year should be very close to the league-average OBP.

UBR (Ultimate Base Running) – Ultimate Base Running is FanGraph’s way of accounting for the value a player adds to their team via base running. This value is determined using linear weights, with each individual base running event receiving a specific run value.

WAR (Wins Above Replacement) – Wins Above Replacement is an attempt by the sabermetric baseball community to summarize a player’s total contributions to their team in one statistic.  WAR basically looks at a player and asks the question, “If this player got injured and their team had to replace them with a minor leaguer or someone from their bench, how much value would the team be losing?” This value is expressed in a wins format, so we could say that Player X is worth +6.3 wins to their team while Player Y is only worth +3.5 wins.

FIP (Fielding Independent Pitching)Fielding Independent Pitching measures what a player’s ERA should have looked like over a given time period, assuming that performance on balls in play and timing were league average.  FIP’s concept is based on the idea that pitchers have little control over balls hit in play.  A better way to assess a pitcher’s talent level is by looking at results a pitcher can control: strikeouts, walks, hit by pitches, and homeruns.  It is set to the same scale as ERA, so a league average FIP in a given year should be the same as the league average ERA.

UZR (Ultimate Zone Rating) – Ultimate Zone Rating puts a run value to defense, attempting to quantify how many runs a player saved or gave up through their fielding prowess (or lack thereof).  Components that make up UZR include outfield arm strength, infielder ability to turn the double play, the range of the fielder, and errors committed.  UZR/150 is UZR, scaled to 150 games.  As with any advanced defensive statistic, UZR contains a lot of uncertainty, especially in small sample sizes.

Arbitration: Courtroom Showdowns that Should Never Happen (Part 1 of ???)

Posted in Arbitration, Offseason with tags , on March 19, 2013 by oriolesprovingground

The purpose of this post originally came about this offseason with a simple question.  If a team takes one of its players to an arbitration hearing, is that player more likely to leave in free agency once given the chance?  The question seemed simple enough.  And since the Orioles lead the league with 15 players eligible for arbitration this year, I thought it was worth investigating.

There have been 505 arbitration hearings since they began in 1974, and they aren’t always friendly (from what I have read, players aren’t required to attend their own hearings, but usually do).  Think about it, if you were forced to defend your value as an employee, you probably wouldn’t appreciate your boss coming into a courtroom to argue why you don’t deserve the salary you think you do.  Once I got the list of every player that has ever gone to a hearing, I quickly realized that finding a relevant answer to this question would probably take a lot longer than the one week deadline I was giving myself.  I’m not making excuses (although I guess technically I am), but as you can imagine, there are a lot of names.  Add in the fact that not all players who go to arbitration reach free agency (therefore not even getting the option to leave), as well as the number of potential changes in the MLB Collective Bargaining Agreement occurring over the years, and almost instantly, my very first post of substance suddenly turned into a multi-part series.  So this first installment will give a brief description of the arbitration process and discuss the Orioles arbitration eligible players.

Once a player is placed on the active major league roster, he is essentially the team’s property for his first 6 years of service time (unless released). During the first 3 years, the team can pay him basically whatever they want, provided it is greater than or equal to the league minimum.  Player’s with more than 3 years, but less than 6 years of service are eligible to file for salary arbitration (a select group of players with less than 3 years of service time, called “super-two’s” are also eligible).  Once a player files for arbitration, both he and his team will submit figures based on what they believe the player’s salary should be for the upcoming season.  If they can’t come to an agreement, they will argue their cases in front of a three-person panel of independent arbitrators, who ultimately decide which salary is more representative of the player’s value in the upcoming season.  In case that last sentence was vague, the arbitrators choose either the player’s requested salary or the teams…nothing in between.  Arbitrators generally base their decisions on how the player performed in the prior year, but also take into account what they have accomplished throughout their career as well.  In presenting their cases, players and teams will compare the player in question to salaries earned by past players who had similar statistics and service time, and reach a decision as to why the player should (or shouldn’t) be paid a certain amount.

That last paragraph was extremely boring to write, so if you actually read the whole thing, give yourself a pat on the back.  You’re either a baseball nerd (like myself), or are a friend who is afraid I’ll ask you questions about whether you read my website.  If you still can’t fill your insatiable need for information on the arbitration process, head over to the Fangraphs glossary for more.  Additionally, if you’re curious on how an arbitration hearing plays out in real life, Baseball Prospectus ran a series of mock arbitration hearings this offseason for 10 different players, including the Orioles Jason Hammel and Jim Johnson (BP subscription required).

As for the Orioles, as I mentioned above they led the league in arbitration eligible players with a whopping 15, including a few that would have had some interesting arguments (form both sides) in an arbitration hearing

  • Nolan Reimold – effective when healthy, but frequently hurt (has already missed 163 games in his short career)
  • Brian Matusz – brief success as a reliever, not so much as a starter (career 5.51 ERA as a starter, 1.35 ERA as a reliever)
  • Tommy Hunter – see Matusz, Brian (career 4.88 ERA as a starter, 3.44 ERA as a reliever)
  • Jim Johnson – closer with only one good year, but a REALLY good year (51 saves in 2012, only 10 career saves prior to 2012)
  • Jason Hammel – one really good year, but also injured (career 4.78 ERA vs. a 3.43 ERA in 2012, but in only 118 innings pitched)

Fortunately for the team and players (and unfortunately for this topic), the Orioles came to agreements with all of their arbitration eligible players prior to going to a hearing (or did not tender a contract, making certain players free agents).  In fact, for the first time since 1974, there were no arbitration hearings for anyone…in the entire league.

So in conclusion, this was a really long post that didn’t do anything to answer the primary question.  Next time, we’ll get a little closer to an answer, fully realizing that it may not be significant.

Welcome!

Welcome to Orioles Proving Ground, a new baseball blog that focuses primarily on the Baltimore Orioles, but may occasionally delve into other general baseball topics from around the league.  My goal for this website is to provide objective analysis of the Baltimore Orioles organization, including everything from the lowest level prospects in the minor leagues, up to the front office.  Not only do I hope to provide some interesting information for prospective readers that happen to stop by, but I also hope to learn something new about baseball along the way.  Once the regular season starts, I’m planning on posting something about once a week.  We’ll see how that goes…

As for me, my name is Nate, and as result of growing up in southeast/central Pennsylvania, I am a fan of the Philadelphia Phillies.  I chose to focus on the Orioles for several reasons.

  • Living in the DC/Baltimore area would allow for easy access to televised and/or live games
  • I recently spent a summer working for the team as a minor league video coordinator, so my current first-hand knowledge of their minor league system is better than any other team
  • I felt I could not write about the Phillies without getting emotional (more anger than crying, but honestly, maybe a little of both) and making subjective arguments
  • I felt like I couldn’t write about the Washington Nationals, since they are currently a model franchise and will likely be one of the many reasons for the Phillies not making the playoffs for several years (with the Phillies front office doing a great job making sure they’re not in the playoffs for several years)

So there you have it.  In the coming weeks before the regular season, look for posts that attempt to tackle the Orioles offseason (or lack of) and the arbitration process.  Also look for mediocre writing skills and bad jokes.  As we get deeper into the season, we’ll also try to get some guest authors in here as well.  See you next week!
