# Strikeout Rate (K%)

### Definition

Strikeout rate represents the frequency with which a pitcher strikes out hitters, as determined by total strikeouts divided by total batters faced. It's perhaps the most accurate tool for judging a pitcher's ability to strike out hitters.

Another commonly used metric for doing so is K/9 rate, but that's inherently flawed, given that it only takes outs into account for the denominator. If a pitcher strikes out nine across seven innings while giving up a high number of baserunners, why should he rank even with a pitcher who strikes out nine in seven innings with fewer baserunners?

The K rate leaderboards are generally made up of the game's best pitchers. However, plenty of pitchers have succeeded with lower strikeout rates, generally because they are able to induce weak contact.

##### Example

Watch: David Price fans the side to increase his strikeout rate.

### Fantasy advantage

Strikeouts are valuable to fantasy owners and K rates correlate closely to strikeout totals. Additionally, pitchers with high K rates tend to be among the best at notching impressive ERA and WHIP figures.
