This is a forward-tracked first-inning model play. The listed price is a synthetic -110 benchmark unless a live sportsbook feed verifies a different playable number.

This is the highest EV row on the May 7 first-inning card. The model is pricing the chance of one early run above the standard -110 break-even point, and the posted guidance is simple: play the YRFI only if the market is still around -110 or better.

The important part is not just the side, it is the price ceiling. First-inning props compress all variance into six outs, so a small model edge can disappear quickly if the market moves. The listed play should be treated as playable only near the published benchmark.

Tracked play: Pittsburgh Pirates @ Arizona Diamondbacks YRFI at -110. Model probability 55.59%, edge 3.21%, EV 6.14%. Result pending.

Why It Made The May 7 Card

The May 7 first-inning board produced three official rows. This game cleared the minimum edge and EV gates, which is why it gets a standalone page instead of being buried as a watchlist note.

Nothing here should be read as a guaranteed early run or guaranteed quiet inning. The model is saying the probability is high enough relative to the price to justify a one-unit pregame position.
