There's a tiny game of checkers going on in every part of the universe. Sadly, all of these games are stalemate. The tiny little microscopic adam dudes are all pissed that they can't win, and their anger is totally making waves. These waves generate electromagnetic energy which metal totally vibes to.

Then you have the Death Attraction Ratio:

Everytime someone dies while a metallica song is being played somewhere in the world all of the little metal pieces are all like "F YEAH!!!" and run over towards the magnet of metal to rock out to some Metallica.

Pretty simple stuff, really.

More detailed Statistics:

A-Assists. The number of times a fielder makes a throw that results in an out.

AB-At Bats

AB/RSP-At Bats with Runners in Scoring Position (second and/or third base).

BA-Batting Average, Hits divided by At Bats.

BA/RSP-Batting Average with Runners in Scoring Position (second and/or third base).

BABIP-Batting Average on Balls in Play. This is a measure of the number of batted balls that safely fall in for a hit (not including home runs). The exact formula we use is (H-HR)/(AB-K-HR+SF) This is similar to DER, but from the batter's perspective.

BB-Bases on Balls, otherwise known as walks.

BB/G-Walks Allowed per games pitched. This stat is based on the number of walks allowed divided by total number of batters faced, times the average number of batters per game in that specific league (generally around 38 batters a game).

BFP-Batters Faced by Pitcher. The pitching equivalent of Plate Appearances for batters.

BIZ-Balls in Zone, a fielding stat that represents the total number of balls that were batted into a fielder's zone while he was in the field.

BR, or Base Runs-A run contribution formula which quantifies the number of runs contributed by a batter. The fundamental formula for Base Runs is (baserunners times scoring rate) plus home runs.

BsR-Base Runs. Base Runs estimates the number of runs a team "should" have scored given their component offensive statistics, as well as the number of runs a hitter/pitcher creates/allows

Clutch-"Clutch" is the name we've given to the portion of Bill James's Runs Created formula that includes the impact of a batter's batting average with runners in scoring position and the number of home runs with runners on. The specific formula is Hits with RISP minus overall BA times at bats with RISP, plus HR with runners on minus (all HR/AB) times at bats with runners on. This stat is not a definitive description of "clutch hitting," just one way of looking at it.

CS-Caught Stealing

CWS-Often stands for College World Series, but it's Career Win Shares.

DER-Defense Efficiency Ratio. The percent of times a batted ball is turned into an out by the teams’ fielders, not including home runs. The exact formula we use is (BFP-H-K-BB-HBP-Errors)/(BFP-HR-K-BB-HBP). This is similar to BABIP, but from the defensive team's perspective. Please note that errors include only errors on batted balls.

DIPS-defense-independent pitching statistic. measures a pitcher's effectiveness based only on plays that do not involve fielders: home runs allowed, strikeouts, hit batters, walks, and, more recently, fly ball percentage, ground ball percentage, and (to much a lesser extent) line drive percentage. Those plays are under only the pitcher's control in the sense that fielders (not including the catcher) have no effect on their outcome.

DP-Double Plays

DPS-Double Plays Started, in which the fielder typically gets only an assist.

DPT-Double Plays Turned, in which the fielder records both an assist and an out.

ERA-Earned Run Average. Number of earned runs allowed divided by innings pitched multiplied by nine.

ERA+ -ERA measured against the league average, and adjusted for ballpark factors. An ERA+ over 100 is better than average, less than 100 is below average.

EqA-Equivalent Average. Intended to express the production of hitters in a context independent of park and league effects.[1] It represents a hitter's productivity using the same scale as batting average. Thus, a hitter with an EqA over .300 is a very good hitter, while a hitter with an EqA of .220 or below is poor. An EqA of .260 is defined as league average.

Expected Win Shares-Expected Win Shares are a playing time metric. They are the number of Win Shares a player would be expected to accumulate, given his playing time (including plate appearances, innining in the field, and innings pitched), if he were an average player. Expected Win Shares is a baseline for evaluating Win Shares totals, as in Win Shares Above Bench.

FE-Fielding Errors, as opposed to Throwing Errors (TE)

FIP-Fielding Independent Pitching, a measure of all those things for which a pitcher is specifically responsible. The formula is (HR*13+(BB+HBP-IBB)*3-K*2)/IP, plus a league-specific factor (usually around 3.2) to round out the number to an equivalent ERA number. FIP helps you understand how well a pitcher pitched, regardless of how well his fielders fielded.

FPct -Fielding Percentage, or the number of fielding chances handled without an error. The formula is (A+PO)/(A+PO+E).

G -Games played.

GB% -The percent of all batted balls (not just outs) that are groundballs.

G/F -G/F stands for Groundball to Flyball Ratio. It is the number of groundballs divided by the number of flyballs (but not line drives) hit by the batter or allowed by the pitcher. It includes all batted balls, not just outs.

GIDP (or GDP) -The number of times a batter Grounded Into Double Plays.

GPA-Gross Production Average, a variation of OPS, but more accurate and easier to interpret. The exact formula is (OBP*1.8+SLG)/4, adjusted for ballpark factor. The scale of GPA is similar to BA: .200 is lousy, .265 is around average and .300 is a star. A simple formula for converting GPA to runs is PA*1.356*(GPA^1.77).

GS -Games Started, a pitching stat.

HRA -Home Runs Allowed, also a pitching stat.

HR/Fly or HR/F -Home Runs as a percent of outfield flyballs. The home run totals are adjusted by the home ballpark's historic home run rates. Research has shown that about 11% to 12% of outfield flies are hit for home runs. For pitchers, significant variations from 11% are probably the result of "luck," but for hitters this stat is more indicative of a true skill (hitting the ball hard!).

HR/G -Home Runs Allowed per games pitched. This stat is based on the number of home runs allowed divided by total number of batters faced, times the average number of batters per game in that specific league (generally around 38 batters a game).

IBB-Intentional Base on Balls.

IF/Fly or IF/F -The percent of flyballs that are infield flies. For some pitchers, inducing infield flies may be a repeatable skill.

ISO -Isolated Power, which measures the “true power” of a batter. The formula is SLG-BA.

K-Strikeouts

K/G -Strikeouts per games pitched. This stat is based on the number of strikeouts divided by total number of batters faced, times the average number of batters per game in that specific league (generally around 38 batters a game).

L-Losses

LD% -Line Drive Percentage. Baseball Info Solutions tracks the trajectory of each batted ball and categorizes it as a groundball, fly ball or line drive. LD% is the percent of batted balls that are line drives. Line drives are not necessarily the hardest hit balls, but they do fall for a hit around 75% of the time.

Leverage Index -Leverage Index is a measure of how critical a specific batting situation is. One (1) is average, anything above one is more critical and anything less than 1 is less critical. .

LIPS-late-inning pressure situation.a Late Inning Pressure Situation is "any at-bat in the seventh inning or later, with the batter's team trailing by three runs or less (or four runs if the bases were loaded)

LOB and LOB%-LOB stands for Left On Base. It is the number of runners that are left on base at the end of an inning. LOB% is slightly different; it is the percentage of baserunners allowed that didn't score a run. LOB% is used to track pitcher's luck or effectiveness (depending on your point of view). The exact formula is (H+BB+HBP-R)/(H+BB+HBP-(1.4*HR)).

OBP-On Base Percentage, the proportion of plate appearances in which a batter reached base successfully, including hits, walks and hit by pitches. The specific formula is (H + BB + HBP) divided by (AB + BB + HBP + SF). OBP is also a powerful performance metric when interpreted as the percentage of times the batter didn't make an out.

OOZ -Out Of Zone, or the total number of outs made by a fielder on balls hit outside of his zone.

Op -Save Opportunities

OPS -On Base plus Slugging Percentage, a crude but quick measure of a batter’s true contribution to his team’s offense. See GPA for a better approach.

OPS+ -OPS measured against the league average, and adjusted for ballpark factors. An OPS+ over 100 is better than average, less than 100 is below average.

P-Measures the criticality of a reliever's appearance. It is computed by estimating the impact a successful relief appearance would have on a team's WPA.

PGS-Pitches per Game Started (only shown for pitchers who have started in 100% of their appearances).

P/PA-Pitches per Plate Appearance.

PA -Plate Appearances, or AB+BB+HBP+SF+SH.


PO -Putouts, the number of times a fielder recorded an out in the field. First basemen and outfielders get lots of these. From a pitching perspective, PO stands for pick offs -- the number of times a pitcher picks a baserunner off a base.

POS-Position played in the field.

PR (Pitching Runs) -measure of the number of runs a pitcher saved compared to average. The formula is league-average RA/IP minus park-adjusted RA/IP, times total innings pitched.

PRC-The notion behind Pitching Runs Created is that a run saved is worth more than a run scored, and PRC puts runs saved on the same scale as runs scored. You can directly compare PRC to a batter's Runs Created to gauge each player's relative value to his team..

PrOPS-PrOPS stands for "Predicted OPS." PrOPS isn't really a new stat; it's a formula for predicting what a player's OPS is likely to be in the future based on his batted balls, strikeouts, home runs and walks.

Pythagorean Record-A formula for converting a team’s Run Differential into a projected Won/Loss record. The formula is RS^2/(RS^2+RA^2). Teams’ actual won/loss records tend to mirror their Pythagorean records, and variances can usually be attributed to luck.
You can improve the accuracy of the Pythagorean formula by using a different exponent (the 2 in the formula). In particular, a sabermetrician named US Patriot discovered that the best exponent can be calculated this way: (RS/G+RA/G)^.287, where RS/G is Runs Scored per game and RA/G is Runs Allowed per game. This is called the PythagoPat formula.

R-Runs Scored and/or Allowed.

R/G-Runs Scored Per Game. Literally, R divided by games played.

RA -Runs Allowed Per Nine Innings. Just like ERA, but with unearned runs, too.

RBI-Runs Batted In

RC-Runs Created. Invented by Bill James, RC is a very good measure of the number of runs a batter truly contributed to his team’s offense. The basic formula for RC is OBP*TB, but it has evolved into over fourteen different versions. We use the most complicated version, which includes the impact of hitting well with runners in scoring position, and is adjusted for ballpark impact. RC/G refers to Runs Created Per Game, which Runs Created divided by the number of outs made by the batter, times 27.

RCAA -Runs Created Above Average. Calculates each player’s Runs Created, and then compares it to the league average, given that player’s number of plate appearances.

RF-Range Factor, a measure of the total chances fielded in a player’s playing time. The formula we use is 9*(PO+A)/Innings in Field.
RS-Runs Scored

RSAA -Runs Saved Above Average. A measure of a pitcher’s effectiveness and contribution. The formula is RA/IP minus league-average RA/IP, times total innings pitched.

Run Differential-Runs Scored minus Runs Allowed.

RZR (or ZR)-Revised Zone Rating is the proportion of balls hit into a fielder's zone that he successfully converted into an out.

SB -Stolen Bases

SB%-The percent of time a runner stole a base successfully. The formula is SB/SBA.

SBA-Stolen Bases Attempted.

SBA/G-Stolen Base Attempts per 9 innings played.

ShO -Shutouts

SLG and SLGA-Slugging Percentage. Total Bases divided by At Bats. SLGA stands for Slugging Percentage Against. It represents SLG from the pitcher's perspective.

SO -Strikeouts

Sv -Saves

Sv%-Saves divided by Save Opportunities

TB -Total Bases, calculated as 1B+2B*2+3B*3+HR*4.

TBA-Total Bases Allowed. A pitching stat.

TE -Throwing Errors, as opposed to Fielding Errors (FE).

UER-Unearned Runs

UERA-Unearned Run Average, or the number of unearned runs allowed for each nine innings pitched.

W -Wins

WHIP -Walks and Hits Per Inning Pitched, a variant of OBP for pitchers. This is a popular stat in rotisserie baseball circles.

wOBA-weighted on-base average. a statistic, based on linear weights, designed to measure a player's overall offensive contributions per plate appearance. It is formed from taking the observed run values of various offensive events, dividing by a player's plate appearances, and scaling the result to be on the same scale as on-base percentage. Unlike statistics like OPS, wOBA attempts to assign the proper value for each type of hitting event.

WPA-Win Probability Added. A system in which each player is given credit toward helping his team win, based on play-by-play data and the impact each specific play has on the team's probability of winning.

WP+PB/G-Wild Pitches and Passed Balls per Nine Innings played. A fielding stat for catchers.

WS-Win Shares.Win Shares is a very complicated statistic that takes all the contributions a player makes toward his team’s wins and distills them into a single number that represents the number of wins contributed to the team, times three.

WSAB-Win Shares Above Bench, or Baseline. WSAB is a refined approach to Win Shares, in which each player's total Win Shares are compared to the Win Shares an average bench player would have received, given that player's time at bat, on the mound or in the field..

WSP -Win Shares Percent, a Win Shares "rate stat" -- a measure of the player's contribution, given his playing time. The math is WS/(2*ExpWS). Expected Win Shares are the number of Win Shares an average player contributed, given that particular player's time at bat, on the mound or in the field.

xFIP -Expected Fielding Independent Pitching. This is an experimental stat that adjusts FIP and "normalizes" the home run component. Research has shown that home runs allowed are pretty much a function of flyballs allowed and home park, so xFIP is based on the average number of home runs allowed per outfield fly. Theoretically, this should be a better predicter of a pitcher's future ERA.

VORP-value over replacement player. demonstrates how much a hitter contributes offensively or how much a pitcher contributes to his team in comparison to a fictitious "replacement player," who is an average fielder at his position and a below average hitter.

Zone-The areas on a ballfield in which at least 50% of batted balls are handled for outs. Zones are standardized and defined separately for each position.

Because the millions of the Big Papi and Jeter fans would cry out in horror and clutch their baseball cards in fear at the thought of the clutchiest clutch players in baseball not being very clutch.
