+6 pts
STRIKES OUT MORE
Published Monday, September 21, 2026
Christian Koss is a worse strikeout risk than usual tonight, and his season strikeout rate does not show it. He strikes out 30% of the time against the kind of pitches Zebby Matthews throws, compared with 23% against everyone else — 6 points worse. The reason is the slider: Zebby Matthews throws it 22% of the time, and Christian Koss strikes out 46% of the time against it across 22 plate appearances. A season strikeout rate averages every kind of pitcher he has faced, so a matchup like this disappears into it.
