BetMan’s Gut Pick

Atlanta Braves @ Chicago Cubs — Chicago Cubs

Cubs are the one true favorite on this whole slate and that -135 price feels honest, not steep. I’m laying the number and rolling with the better team at home.

Gut, not gospel — the value board is the math.

YRFI / NRFI Leans

BetMan’s First-Inning Call

NRFI — Milwaukee Brewers @ Pittsburgh Pirates

Misiorowski’s a 1.95 ERA buzzsaw and the model’s screaming NRFI at 62 percent, that’s about as clean an alignment as you get. Riding the ace here, no reason to overthink it.
