Chris Sale and Jacob Misiorowski each carry an identical 86% first-inning scoreless rate, and both have been locked in lately — Sale at 4-of-5, Misiorowski a perfect 5-of-5 over his last five. Neither offense does much early either, with Milwaukee at 28% and Atlanta at 29%, so the pitching-friendly 94 park factor only reinforces the NRFI lean here.
- NRFI lean — Chris Sale (86% NRFI) and Jacob Misiorowski (86%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -196 (63% implied); the model has it 57%.
- The Milwaukee Brewers score in the first in 28% of games, 20th-most in MLB, 34% against left-handers.
- The Atlanta Braves score in the first in 29% of games, 16th-most in MLB, 28% against right-handers.


Jesus Luzardo has kept the first frame clean in a remarkable 96% of his 24 starts, and he's put up five straight scoreless firsts. On the other side, Hunter Dobbins matches that recent streak with a 86% NRFI rate. Neither offense scores early often — Philadelphia at 27% versus righties, St. Louis at 31% versus lefties — nudging this toward a scoreless first despite the hitter-friendly park factor of 102.
- NRFI lean — Hunter Dobbins (86% NRFI) and Jesus Luzardo (96%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -129 (36% implied); the model has it 53%.

- The St. Louis Cardinals score in the first in 31% of games, 12th-most in MLB, 31% against left-handers.


Cam Schlittler is the anchor here, sitting on an 84% NRFI mark across 25 starts and posting a clean first frame in four of his last five. It helps that Toronto's bats rank dead last in first-inning scoring at just 22%, and only 24% against righties. With Fluharty's smaller sample holding steady too, the model's 56% scoreless edge feels earned.
- NRFI lean — Mason Fluharty (67% NRFI) and Cam Schlittler (84%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -137 (54% implied); the model has it 56%.
- The New York Yankees score in the first in 29% of games, 17th-most in MLB, 37% against left-handers.
- The Toronto Blue Jays score in the first in 22% of games, 30th-most in MLB, 24% against right-handers.


Logan Webb's 81% NRFI over 21 starts anchors this lean, and he's stretched it to 4 of his last 5. Sonny Gray answers with a spotless 5-for-5 first-inning run in his recent outings, facing a Giants lineup that scores in the opening frame just 19% of the time against righties. Fenway's 108 park factor keeps it from being a stronger NRFI.
- NRFI lean — Logan Webb (81% NRFI) and Sonny Gray (73%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -157 (57% implied); the model has it 55%.

- The San Francisco Giants score in the first in 22% of games, 29th-most in MLB, 19% against right-handers.


Trevor Rogers has been airtight early, posting an 86% first-inning shutout rate across 22 starts and cleared all five of his last five. He faces a Rays offense that plates a first-inning run just 30% of the time against left-handers. Freddy Peralta's 71% NRFI mark rounds out a matchup that tilts toward a quiet opening frame in Baltimore.
- NRFI lean — Freddy Peralta (71% NRFI) and Trevor Rogers (86%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -122 (51% implied); the model has it 54%.

- The Tampa Bay Rays score in the first in 33% of games, 7th-most in MLB, 30% against left-handers.


Emerson Hancock's 76% first-inning shutout rate across 21 starts anchors this NRFI lean, and Matthew Boyd matches him well at 71% over 14 outings. Neither offense does much early either — the Cubs plate a run in the first just 26% of the time, the Mariners 29% — and T-Mobile Park's run factor of 83 only tightens things further.
- NRFI lean — Matthew Boyd (71% NRFI) and Emerson Hancock (76%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -125 (52% implied); the model has it 58%.

Coors Field is doing the heavy lifting here, with its 128 run factor tilting things toward a run crossing early. Tanner Gordon's modest 60% NRFI mark over five starts doesn't inspire much first-inning confidence, and Colorado's bats score in the opening frame 36% of the time against lefties like Joey Cantillo. Even Cantillo's strong 76% NRFI rate gets tested in this environment, nudging the lean toward YRFI.
- YRFI lean — Coors Field (run factor 128) is one of the league's most hitter-friendly parks, and the Colorado Rockies score early in 33% of games.
- Books price this NRFI at +110 (45% implied); the model has it 43%.
- The Colorado Rockies score in the first in 33% of games, 5th-most in MLB, 36% against left-handers.
- The Cleveland Guardians score in the first in 27% of games, 22nd-most in MLB, 26% against right-handers.

Ryan Gusto's 73% first-inning shutout rate over 11 starts is the sturdiest number on the board, and the Marlins' bats plate a run in the first just 28% of the time. But Washington's lineup is more dangerous, ranking sixth in MLB at scoring early and doing it 33% against righties like Brad Lord. That tug-of-war lands this one squarely at a coin flip.
- Coin flip — Ryan Gusto's 73% NRFI is the case for the under; the Washington Nationals' 33% first-inning bats (6th-most in MLB) are the case for the over.
- Books price this NRFI at -132 (53% implied); the model has it 49%.
- The Miami Marlins score in the first in 28% of games, 21st-most in MLB, 29% against right-handers.
- The Washington Nationals score in the first in 33% of games, 6th-most in MLB, 33% against right-handers.


Sean Burke's 75% first-inning zero rate over 20 starts headlines this one, and he's backed by Manaea, who's carried a scoreless first in five straight. The bats don't push back much either — the Mets score in the opening frame just 27% of the time. Even so, the White Sox rank ninth in MLB for first-inning offense, which keeps this closer to a coin flip at 51%.
- Coin flip — Sean Burke's 75% NRFI is the case for the under; the Chicago White Sox's 32% first-inning bats (9th-most in MLB) are the case for the over.
- Books price this NRFI at -141 (55% implied); the model has it 51%.
- The Chicago White Sox score in the first in 32% of games, 9th-most in MLB, 33% against left-handers.
- The New York Mets score in the first in 27% of games, 24th-most in MLB, 25% against right-handers.


J.T. Ginn brings an elite 82% first-inning shutout rate into Daikin Park, but he'll face a Houston lineup that plates a run in the opening frame 34% of the time — third-most in MLB and 37% against righties. That tension is exactly why this one splits down the middle at 50%, right in line with the book's 52% NRFI read.
- Coin flip — J.T. Ginn's 82% NRFI is the case for the under; the Houston Astros' 34% first-inning bats (3rd-most in MLB) are the case for the over.
- Books price this NRFI at -120 (52% implied); the model has it 50%.
- The Houston Astros score in the first in 34% of games, 3rd-most in MLB, 37% against right-handers.

Noah Cameron has been elite in openers for Kansas City, holding an 83% NRFI mark across 23 starts and slamming the door in his last five. The tension is Detroit's bats, who plate a first-inning run in 34% of games — second-most in MLB — though only 30% against lefties. With Melton solid at 64% NRFI, it's a genuine toss-up at 49%.
- Coin flip — Noah Cameron'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 -125 (52% implied); the model has it 49%.

Reid Detmers brings a strong 75% first-inning shutout rate into Globe Life Field, and MacKenzie Gore isn't far behind at 68%, giving both starters the edge on paper. The wrinkle is the Angels' bat: LA leads MLB in first-inning scoring at 34%, and 37% against lefties like Gore. With those forces pulling against each other, the model lands at a near-even 51% NRFI.
- Coin flip — Reid Detmers' 75% 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 -145 (55% implied); the model has it 51%.

- The Los Angeles Angels score in the first in 34% of games, the most in MLB, 37% against left-handers.


Nick Lodolo brings the sharper first-inning profile here, holding a 79% NRFI mark across 14 starts and stranding trouble in four of his last five. The counter is Chase Field's 106 run factor and Eduardo Rodriguez's shakier 58% NRFI. With both lineups scoring early roughly a quarter of the time, the model lands at 48% scoreless — essentially a coin flip against the book's 51%.
- Coin flip — Nick Lodolo's 79% NRFI is the case for the under; the Arizona Diamondbacks' 30% first-inning bats (13th-most in MLB) are the case for the over.

Two strong first-inning arms headline this one, with Bubba Chandler protecting a 78% NRFI mark and Yamamoto right behind at 71%, both scoreless in four of their last five. The offenses don't push back much either — the Dodgers plate a first-inning run just 31% of the time, the Pirates 30% — but Dodger Stadium's slightly elevated run factor keeps it at a genuine coin flip.
- Coin flip — Bubba Chandler's 78% NRFI is the case for the under; the Los Angeles Dodgers' 31% first-inning bats (11th-most in MLB) are the case for the over.
