What is MLB CSW?
MLB CSW was created by Nick Pollack and Alex Fast of Pitcher List in 2018 and is described as being more predictive than swinging strike percentage.
CS = Called strikes plus W = whiffs, which is then divided by total pitches.
A strong CSW in DFS MLB is anything over 30, and can help indicate a starting pitcher in a great spot to rack up strikeouts that day.

Key Statistics Provided
CSW (History and Projection for the Day)
CSW, or Called Strikes plus Whiffs, is a metric that measures a pitcher's ability to generate swings and misses. This is an important statistic to consider when evaluating a pitcher's potential for success in daily fantasy baseball. Our algorithm generates both a historical CSW for each pitcher and a projection for the day, giving you a complete picture of their performance over time and how they're expected to perform on game day.
K% (Strikeout Percentage)
K%, or Strikeout Percentage, is another important statistic to consider when evaluating a pitcher's potential for success. It measures the percentage of plate appearances that result in a strikeout, and can give you a good idea of a pitcher's ability to generate outs. Our data provides both a historical K% for each pitcher, as well as a projection for the day, so you can see how they've performed in the past and what you can expect from them in the present.
SIERA (Skill-Interactive Earned Run Average)
SIERA, or Skill-Interactive Earned Run Average, is a metric that measures a pitcher's overall performance and their ability to prevent runs. Unlike traditional ERA, SIERA takes into account a variety of factors, including strikeouts, walks, fly balls, and ground balls. By providing a complete picture of a pitcher's performance, SIERA can help you make more informed decisions when building your daily fantasy lineup.
Opponent Stats
In addition to data on each individual pitcher, we also provide key statistics on their opponents. This includes the CSW, K%, wOBA, and WRC of the opposing team. Knowing how each pitcher is likely to perform against their opponent can give you a significant edge in daily fantasy baseball, allowing you to make smarter choices and increase your chances of success.
As a resource, we're dedicated to providing you with the most accurate and up-to-date pitcher data available. By combining algorithm-generated stats with expert analysis and insights, we're confident that you'll have everything you need to build a winning lineup each day and take your daily fantasy baseball game to the next level.
Frequently Asked Questions
- What is MLB CSW?
- CSW stands for Called Strike plus Whiff rate — the percentage of a pitcher's total pitches that result in either a called strike or a swinging strike. It is widely considered one of the best single-stat predictors of strikeout ability. A CSW above 30% is elite; league average is approximately 27-28%.
- How is CSW used in DFS?
- In MLB DFS, CSW helps identify pitchers most likely to rack up strikeouts — the highest-value stat for DFS pitchers on DraftKings (2 pts each) and FanDuel (3 pts each). Pairing a high-CSW pitcher with an opponent that has a high team strikeout rate is a core DFS strategy for maximizing pitcher scoring.
- What is a good CSW rate for a starting pitcher?
- A CSW rate above 30% is considered elite and indicates a pitcher who misses bats and commands the strike zone at a high level. Between 28-30% is above average, 26-28% is around league average, and below 26% suggests a pitcher who relies more on contact management than pure stuff.
