Michael Harris II vs Mitch Keller

The Almanac's Take

Harris has the platoon edge here as a lefty against Keller's right-handed stuff, and his season numbers back it up — .298/.329/.482 with 14 home runs across 319 PA is legitimate production, not a hot stretch. Keller's 5.02 ERA and 1.31 WHIP over 100.1 innings suggest a pitcher who's been hittable all year, and his 6.6 K/9 means Harris's 21.3% strikeout rate isn't a disqualifying concern. The head-to-head is 15 PA — 4 hits, 5 strikeouts, an 85.0 mph average exit velocity — thin enough to treat as background noise. The season read is the real story.
