Baseball season groove betting system

April baseball lies: cold weather, unsettled rotations and rusty hitters distort both results and totals. This template waits for the season to find its groove, then backs home teams with a solid recent record against the run line, in matches priced for normal scoring.

How the filter tree works

• Month: only games from May through September qualify, skipping the April noise and the October playoffs.
• Spread cover rate: the home team covered the run line in at least 55% of its last 20 games, with a minimum of 10 games.
• Line value: the closing total must sit between 7 and 9.5 runs, filtering out extreme park and weather situations.

What to watch

• The total-range condition is a context filter: it does not bet the total, it uses it to exclude weird run environments.
• 55% covering over 20 games is a gentle signal; expect a large sample with modest selectivity.
• Baseball's daily schedule means streaks and slumps churn quickly through a 20-game window.

Tweaks to try

• Tighten the cover rate to 60% and compare.
• Split May to June from August to September to check stability inside the window.
• Swap the home side for road coverers as a control.
