Quick Answer
Today's honest first-inning read is mostly a pass, because every edge on the 10-game board grades negative. Treat these as trends to know, not tickets to punch; three still stand out before lineups lock.
Prices pulled at 10:40 a.m. ET; first pitches from 5:05 p.m. ET.
Ten MLB games carry a first-inning market Monday, August 17: Janson Junk hasn't allowed a first-inning run since May 20, the Padres own baseball's quietest first inning, and Dodgers–Rockies sits at Coors. Quiet side first, then the runs side.
Junk Hasn't Allowed A First-Inning Run Since May 20
Marlins At Phillies: Junk Vs. Cristopher Sánchez, NRFI -108
Janson Junk has a clean first in eight straight starts (eight of his last 10); his last first-inning run was May 20. Cristopher Sánchez matches him with six straight scoreless firsts, and Miami scores in the first just 43% of the time versus a 50% league rate. Citizens Bank Park's 58% first-inning rate is the pushback, so this only shades to NRFI -108.
The trend read: two arms untouched early against a quiet Marlins order, a real NRFI lean the price already found.
The Padres Own Baseball's Quietest First Inning
Padres At Mets: Walker Buehler Vs. Nolan McLean, NRFI -125
San Diego sees a first-inning run in just 38% of its games, the lowest rate in MLB and 12 points under average. Walker Buehler is riding six straight clean firsts (last first-inning run July 11), Nolan McLean is at seven of 10, and Citi Field is neutral at 48%. It's the board's sturdiest NRFI profile, and the priciest, at -125.
The trend read: lineup and arm point the same quiet way, and you're just paying up for it.
Coors Is Still Coors
Dodgers At Rockies: Blake Snell Vs. Tomoyuki Sugano, YRFI -140
Coors Field has a first-inning run in 75% of its games this year, 17 points clear of any other park on the slate. The Rockies lead MLB at a 65% team rate, and Tomoyuki Sugano has been the softest opening arm, clean in just four of his last 10 (Blake Snell, two starts off the injured list, is a thin sample). The board prices YRFI -140; the contrarian NRFI +126 is the board's top-ranked number today, and even that grades negative.
The trend read: the park screams runs; the only case back is that plus-money NRFI ticket, and it doesn't beat fair.
When The Board Says No
Today is mostly a pass: every one of these edges grades negative, so the move is to watch, not fire. The board's three least-bad numbers are Dodgers-Rockies NRFI +126 and the Marlins-Phillies and Orioles-Rays YRFI +102s; those are the ones worth re-checking around 4 p.m. once lineups post and the weather firms up. Two more watch items: Boston still hadn't named a starter opposite Arizona's Mitch Bratt, and Coors wind and heat swing that 75% number more than any pitcher does.

FAQ
What are the best NRFI picks today, Monday, August 17? These three storylines are the ones worth knowing: Marlins–Phillies NRFI -108 (Junk and Sánchez both on scoreless-first streaks), Padres–Mets NRFI -125 (San Diego's MLB-low 38% first-inning rate behind Buehler), and, on the runs side, Dodgers–Rockies YRFI -140 at Coors. Every edge on the board grades negative today; the least-bad numbers are Dodgers-Rockies NRFI +126 and the Marlins-Phillies and Orioles-Rays YRFI +102s, so treat all of these as reads to shop, not plays to chase.
What do NRFI and YRFI mean? NRFI ("no runs first inning") cashes if neither team scores in the first; YRFI ("yes runs first inning") cashes if either team does. It's a single-inning bet on both starters and both lineups' top thirds.
Where can I shop first-inning odds? The OddsShopper first-inning Odds Screen lists NRFI/YRFI prices across 100-plus books, and OS Pro's no-vig pricing shows the "true" line next to each so you can find the best number.
