Sandy Alcantara has kept the first inning clean in 85% of his 26 starts, and Ranger Suarez isn't far behind at 76% — both are riding five straight scoreless openers. Neither offense pushes back much either: Boston plates a first-inning run in just 25% of games (23% against lefties), Miami in 29%. The model's 55% NRFI sits a hair under the book's 56%, so loanDepot park's slightly above-average run factor keeps this from being a runaway lean.
- NRFI lean — Ranger Suarez (76% NRFI) and Sandy Alcantara (85%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -156 (56% implied); the model has it 55%.

Zack Wheeler has kept the first inning clean in 86% of his 21 starts, and T-Mobile Park's 83 run factor only tightens the screws further. Seattle's offense has scored in the opening frame just 30% of the time, dropping to 28% against righties, so Wheeler's side of the ledger does most of the heavy lifting here. Gilbert's 63% NRFI rate is the softer half, which is why this leans rather than screams.

Robbie Ray has kept the first inning clean in 83% of his 23 starts, including each of his last five, and he draws a Pirates lineup that plates a first-inning run just 18% of the time against left-handers. Braxton Ashcraft counters at 75% NRFI, facing a Padres offense ranked 28th in first-inning scoring at 24%. Petco's 94 run factor nudges it further — the model's 56% sits three points above the book's 53%.

Chase Burns has kept the first inning clean in 91% of his 23 starts, and he's drawing a Giants lineup that scores in the opening frame just 23% of the time — only 19% against righties. Carson Whisenhunt is the softer side of this, at 57% NRFI across seven starts with two clean firsts in his last five, but Oracle Park's 94 run factor helps him. Model sits at 58%, a shade past the market's 55%.
- NRFI lean — Chase Burns has worked a scoreless first in 91% of his starts, the headline edge in a quiet matchup.

Kumar Rocker has kept the first frame clean in only 45% of his 22 starts, and Chicago's lineup puts a run on the board in the opening inning 31% of the time — 12th-most in baseball. Jose Urquidy is the wild card, with no starts logged this season, so there's little to go on against Texas. The model's 47% scoreless sits close to the market's 50%, so the YRFI tilt is mild.
- YRFI lean — the Chicago White Sox push a first-inning run across in 31% of games (12th-most in MLB), hard to keep off the board early.
- Books price this NRFI at -111 (50% implied); the model has it 47%.
- The Chicago White Sox score in the first in 31% of games, 12th-most in MLB, 28% against right-handers.
- The Texas Rangers score in the first in 28% of games, 20th-most in MLB, 27% against right-handers.


Sutter Health Park's 117 run factor sets a loud backdrop, and neither starter has been especially tidy out of the gate — Zebby Matthews has kept the first inning clean in just 47% of his 17 starts, with only two zeros in his last five. Minnesota's bats are the bigger lever, though: they put a run on the board in the first 34% of the time, fourth-most in the majors. The model's 38% scoreless sits under the market's 43%.
- YRFI lean — Sutter Health Park (run factor 117) is one of the league's most hitter-friendly parks, and the Minnesota Twins score early in 34% of games.
- Books price this NRFI at +118 (43% implied); the model has it 38%.
- The Oakland Athletics score in the first in 29% of games, 17th-most in MLB, 29% against right-handers.
- The Minnesota Twins score in the first in 34% of games, 4th-most in MLB, 34% against left-handers.

Drew Rasmussen has kept the first inning clean in 83% of his 23 starts, including each of his last five — which normally screams NRFI, except Detroit's lineup puts a run on the board in the first 34% of the time, second-most in MLB. Framber Valdez counters at a more ordinary 67%, and with Comerica playing neutral, the model's 49% scoreless read sits a touch under the market's 55%.
- Coin flip — Drew Rasmussen's 83% NRFI is the case for the under; the Detroit Tigers' 34% first-inning bats (2nd-most in MLB) are the case for the over.
- Books price this NRFI at -137.5 (55% implied); the model has it 49%.
- The Detroit Tigers score in the first in 34% of games, 2nd-most in MLB, 35% against right-handers.
- The Tampa Bay Rays score in the first in 32% of games, 10th-most in MLB, 29% against left-handers.


Cade Cavalli has kept the first inning clean in 77% of his 26 starts and is riding a 5-for-5 stretch, which is the strongest argument for a quiet opening frame here. The pushback: both offenses rank top-10 in first-inning scoring — Colorado at 33%, Washington at 32% — and Nationals Park plays slightly hitter-friendly at a 102 run factor. The model's 47% scoreless read sits just under the book's 52%, so it's close to a toss-up.
- Coin flip — Cade Cavalli's 77% NRFI is the case for the under; the Colorado Rockies' 33% first-inning bats (5th-most in MLB) are the case for the over.
- Books price this NRFI at -122 (52% implied); the model has it 47%.
- The Washington Nationals score in the first in 32% of games, 8th-most in MLB, 30% against right-handers.
- The Colorado Rockies score in the first in 33% of games, 5th-most in MLB, 29% against right-handers.


Parker Messick has kept the first inning clean in 92% of his 25 starts, including all five of his last five — but the Angels are the game's most dangerous first-inning club, plating a run 34% of the time and 38% against lefties. George Klassen's 80% mark in a small five-start sample doesn't tilt things much either way, and at 53% the model sits right on the market's number.
- Coin flip — Parker Messick's 92% NRFI is the case for the under; the Los Angeles Angels' 34% first-inning bats (most in MLB) are the case for the over.
- Books price this NRFI at -129 (53% implied); the model has it 53%.
- The Los Angeles Angels score in the first in 34% of games, the most in MLB, 38% against left-handers.
- The Cleveland Guardians score in the first in 28% of games, 21st-most in MLB, 26% against right-handers.


Kevin Gausman and Merrill Kelly have posted nearly identical first-inning résumés — 64% and 65% NRFI respectively, each with four clean opening frames in their last five starts — which normally points toward a quiet start. What keeps it honest is Chase Field's 106 run factor and Arizona's bats, who plate a run in the first 30% of the time. The model's 48% scoreless read matches the market exactly, so there's no edge either direction.
- Coin flip — Merrill Kelly's 65% NRFI is the case for the under; the Arizona Diamondbacks' 30% first-inning bats (14th-most in MLB) are the case for the over.
- Books price this NRFI at -104 (48% implied); the model has it 48%.
- The Arizona Diamondbacks score in the first in 30% of games, 14th-most in MLB, 32% against right-handers.
- The Chicago Cubs score in the first in 26% of games, 25th-most in MLB, 25% against right-handers.
