MLB (Major League Baseball)- is a professional baseball organization. MLB organization is made up of the American League and the National League. Baseball has many abbreviations, acronyms, numbers and statistics and one has to know them to understand the baseball language. I will give a list of some of them to help the readers have an easy time anytime they come across these acronyms.

On Base Percentage /Batting Average /Slugging Percentage

On Base Percentage is the Measure of the player’s rate of reaching base to plate appearances. Batting Average is the measure of a player’s rate of recording hits to make outs. Slugging Percentage is the measure of the total bases accumulation rate to make outs by a player.

OPS-On Base Percentage and Sluggish Percentage

This measures the ability of a player to get on base and to hit for power. It is an effective way of measuring the offensive contribution of a player.

ISO-Isolated Power

It is the measure of the ability of a player to record more bases with a single hit. If a player has high speed and power high ISO values are recorded. Also referred to as, power potential.

wOBA

Weighted on Base Average is the measure of the linear weight of each possible outcome of a plate appearance.

wRC

Weighted Runs Created determines the runs created by a single batter. It measures the sane ways as OPS and gives the contribution of a batter to the league average.

BABIP

Batting Average on Balls in Play- it is the measure of batted balls rate of landing for hits in the playing field. It is also referred to as the measure of players luck.

ERA

Earned Run Average- This measures the overall effectiveness of a player by recording the number of earned runs a pitcher gives up compared to the number of outs their team can record with the pitcher on the mound

WHIP

Walks and Hits per Innings Pitched- this measures the number of baserunners a pitcher will allow for every inning pitched. The measure judges the opposing batters ability to reach base.

xFIP

Expected Fielding Independent Pitching- the measure standardizes the home run term so as to account for the differences in the park size and the luck in home run rates.

tERA

True Era- tracks the flight of the ball and determines each ball’s expected outcome in the play.

UZR- Ultimate Zone Rating- this is the measure of the ability of a defensive player to make plays within specific areas of the field. The field is divided into 78 zones, and the ability of a player to make plays in every of this zones is compared to the ability of other players in the same position.

WAR

Wins above Replacement- this is the measure of how many extra wins a single player would result when added to a particular team. Each player’s ability is compared against a player of average talent that can be available to any team.

Pk- Pickoffs

This is the number of times a runner gets picked off base by a pitcher.

Pivot Percentage

To get this value, the number of double plays by a pivot man is divided by a number of opportunities.

PkOf Throw/Runner

This is the number of the pick-off throws in the game.

Quality start

A quality start is a start in which a pitcher works either six or more innings while still allowing either three or few earned runs.

Quick and Slow Hooks

A Quick Hook describes the removal of a pitcher who has only pitched less than six innings and has also given up three runs or less. If a pitcher pitches 9 and more innings r allows 7 or more runs, or the combined innings and runs pitched add up to 13, this is called a Slow Hook.

Range Factor

The range factor value is arrived at by multiplying by nine the number of chances (putouts +Assists) and dividing by the number of defensive innings.

Baseball is America’s pastime, and, like all sports, there are a number of rules to the game. One of the most misunderstood rules in baseball is the infield fly rule. So, I’m here to help explain a rule many fans don’t understand.

To be perfectly plain, the infield fly rule was introduced to do one particular thing, and that’s to keep the defending team from dropping fly balls on purpose in order to turn double or triple plays. If this rule didn’t exist, then teams would be dropping fly balls all the time. That is not how the game should be played.

Here’s something neat about this rule. After a ball is hit and popped into the air, the batter will be out whether the ball is caught or not caught. Now, ball players in the major leagues rarely misplay a fly ball in the infield, but, the rule is still there if an infielder for the opposing team wants to get a little tricky.

The rule exists since if a defending player were to consistently drop fly balls, it would not be a good show of sportsmanship. In effect, it would be almost like cheating. And, that’s not good for the game, and I believe the fans wouldn’t like it either.

What about batters that have a lot of speed, like the great Ricky Henderson? Opposing teams knew that Henderson was fast, as he stole a lot of bases. And, he made it look easy. Defending teams could drop fly balls to get those really fast players off the bases. So, having the infield fly rule is there to keep some integrity in the game.

See, if a really fast batter stole second, and then a big hitter with a great average came to the plate and was walked, then here we have an interesting scenario. The next batter up could hit a pop fly, and the infielder who would be making the catch could “accidentally” drop it, and force an out at third base. That way, the fast player is off the bases, and slower players are left on. Not in good sportsmanship, right?

But, to be clear about the rule, I can sum it up. To invoke the infield fly rule, there must be less than two outs, and there must be a force play at third base. So, either there are runners at first and second base, or, all bases have runners.

So how is this rule used? Well, if the above conditions exist, and a batter has hit a pop fly, then the umpire will point to the sky to indicate the infield fly rule has just been used. So now, the batter is out automatically, and it doesn’t matter if the ball is dropped or not. He’s out.

The infield fly rule is pretty easy to understand, but, most people don’t know what it is or when it’s used. It keeps some integrity in the game, and keeps cheating and trickery at a minimum.
