MLB Advanced Analytics: CSW Rate: Part Two
Mike Alexander takes another look at CSW% and breaks down which pitchers are inducing the highest rate of called strikes + whiffs.
We’re almost a week into June. Metrics are stabilizing and now’s a great time to check back in on CSW Rate, the strike metric the team over at Pitcher List has been publicizing. Called Strikes plus Whiffs, or CSW, accounts for called strikes, swinging strikes, and foul tips into the glove but excludes foul balls.

Effective pitchers can generate them the most. CSW% is more strongly correlated to SIERA than SwStr% for starting pitchers. If you value SwStr% then CSW% should earn your attention, as well.
