BetMan’s First-Inning Call

NRFI — Pittsburgh Pirates @ Detroit Tigers

Seventy-five percent is the loudest number on the board and River Ryan’s zero backs it up in a big way. Jared Jones is no slouch either, so I’m banking on a scoreless first here.

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