## What Does WHIP MEAN?

**WHIP stands for “Walks and Hits per Innings Pitched” and is a pitching statistic in baseball that tells you the average number of walks and hits per inning that a pitcher gives up**. It is a simple statistic you use to determine how many hits and walks on average a pitcher gives up. You can use this to see the potential for a pitcher to give up runs. Each baserunner is a potential run.

## How to Calculate a Pitcher’s WHIP?

Calculating a pitcher’s WHIP is simple. All you have to do is add the number of walks and hits that a pitcher surrenders. Then you divide that number by the number of innings pitched. The end number is your pitcher’s WHIP. You should keep in mind that WHIP is a statistic based on average. If your pitcher has a limited number of innings then that average may not be an accurate measure of their effectiveness.

## What Does WHIP Not Measure?

You should know that WHIP is not an accurate measurement for all baserunners. WHIP only counts for walks and hits. However, if a player is hit by a pitch that is not covered. Batters who reach base by a fielding or throwing error are not measured. Also, baserunners who get on because of a fielder’s choice are not measured. WHIP also will not tell you how many bases a pitcher gives up. For example, a single, double, triple, or homer all count as the same type of hit in WHIP. So if you have a pitcher who gives up a lot of walks and one that gives up a lot of triples – they may have the same WHIP.

## What is a Good WHIP?

Looking at WHIP statistics, you will see that the better pitchers will have a lower WHIP. If pitchers have a higher WHIP that means they allow more baserunners. The more baserunners you have the more scoring opportunities you have. The pitchers with a lower WHIP reduce baserunners and tend to give up fewer runs.

A good WHIP in baseball is going to be anywhere around a 1. A career WHIP below 1 is rare. There are only two pitchers with a minimum of 1,000 innings pitched that have a WHIP below 1.

## Is WHIP a Good Indicator of a Pitcher’s Success?

WHIP is a good indicator of a pitcher’s success. It is not the only statistic used to measure pitching success. However, WHIP is a good indicator of a pitcher’s success. If you don’t put a lot of runners on base, then there’s a better chance of success. To get a better evaluation of a pitcher, you should use WHIP and ERA together.

## Does WHIP Correlate to Wins?

WHIP does have a strong correlation to wins. The fewer baserunners you allow the harder it is for the other team to score. If you can minimize the number of runs the other team scores, then you can improve your chance for wins. If you have a pitcher with a lower WHIP it is a good indication of their control. If you have a pitcher with a high WHIP, they are probably walking batters or surrendering hits because of a lack of control. What WHIP does not consider is fielding errors and offensive output. This means you could have a very effective pitcher, but an ineffective defense behind them. It also could mean that your pitcher doesn’t give up a lot of runs, but your offense doesn’t score enough to support them. So while there is a correlation, there are some exceptions.
