MLB First-Month Trends Worth Trusting (And Worth Fading)

Three weeks into the 2026 MLB season, here's what to bet on and what to ignore.

Sample sizes are tiny in April. That's a feature, not a bug — public bettors over-react to small samples and the market lags.

Three trends that are real this April:

Strikeout totals are running high. The new pitch clock plus juiced ball pulled back has K rates up 4% league-wide. K props are still pricing toward 2025 baselines. Take overs.
First-five inning unders are profitable. Starters are throwing harder, deeper, and bullpens haven't shaken out. Under F5 has cashed at 56% since opening day.
Home dogs +150 or better. Home dog ROI in April typically runs +3-5%. This year it's +6.2% so far. Don't blow through your bankroll, but the angle is real.
