What happened: Doubles and triples have dropped to their lowest levels in decades across MLB, according to a Wall Street Journal report. The league is considering significant interventions to revive these extra-base hits. This follows years of offensive shifts emphasizing home runs over gap hitting.

Why it matters: Fewer doubles and triples mean lower overall scoring, favoring under bets on game totals and reducing value on certain. Potential rule changes could boost offense, shifting lines upward and reshaping for run production. Historically, similar tweaks like shift bans increased batting averages by 10-15 points.

What to watch: Monitor MLB Competition Committee meetings this offseason for rule change votes, including possible field dimension adjustments.
