Walk Rate

The share of plate appearances that end in a walk. For pitchers, it's walks allowed per batter faced.

8.9%2026 MLB average (2025: 8.4%)

Simple explanation

For a hitter, a walk is a trip to first earned with his eyes. It takes telling balls from strikes and the patience to hold off even when behind in the count.

For a pitcher it's the reverse. A walk puts a runner on without the ball even being put in play, and there's nothing the defense can do about it. For pitchers, lower is better.

plate appearances (batters faced for pitchers)

Pitchers were long judged by walks per nine innings (BB/9). Measured per inning, a pitcher who gives up lots of hits faces more batters each inning, which muddies the number. Dividing by batters faced isolates the walk habit itself.

League average climbed to 8.9% in 2026, up noticeably from 8.4% in 2025.

Power hitters tend to walk a lot and strike out a lot: pitchers work around them, and big swings miss more often. Hitters who focus on contact are usually low in both.
