BetMan’s Gut Pick

Cleveland Guardians @ Baltimore Orioles — Cleveland Guardians

Getting a true coin flip price as the underdog is exactly the kind of spot I like to lean into. Nothing fancy here, just a live dog getting plus money in a game that could go either way.

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

YRFI / NRFI Leans

BetMan’s First-Inning Call

YRFI — Tampa Bay Rays @ Atlanta Braves

Peralta’s ERA sits under 5 and Smith-Shawver is bleeding runs at 7.13, so banking on a zero from either side first inning is wishful thinking. Model’s got this as its strongest lean of the day and the arms back it up completely, that’s my first-inning call.

One call with a little feel behind it — the full board below is the math.
