Jake Bennett has kept the first inning clean in 93% of his 15 starts, and that's the number driving this lean — Boston's lefty simply doesn't hand out early runs. Carlos Rodon backs it up with five straight scoreless openers, facing a Red Sox lineup that scores in the first just 24% of the time and no better against southpaws. The model's 56% edges the book's 53%, with Yankee Stadium playing dead average.
- NRFI lean — Jake Bennett (93% NRFI) and Carlos Rodon (73%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -130 (53% implied); the model has it 56%.
- The New York Yankees score in the first in 28% of games, 19th-most in MLB, 35% against left-handers.
- The Boston Red Sox score in the first in 24% of games, 28th-most in MLB, 24% against left-handers.


Jose Soriano has kept the first inning clean in 76% of his 25 starts, including each of his last five, and Toronto's bats give him plenty of help on the other side — the Blue Jays plate a first-inning run just 23% of the time, 30th in MLB, and only 17% against lefties like Kade Anderson. The catch is Anderson's one-start sample, which is why the 54% model number sits right on the book's 55% and the lean stays mild.
- NRFI lean — Jose Soriano has worked a scoreless first in 76% of his starts, the headline edge in a quiet matchup.
- Books price this NRFI at -142.5 (55% implied); the model has it 54%.
- The Toronto Blue Jays score in the first in 23% of games, 30th-most in MLB, 17% against left-handers.
- The Seattle Mariners score in the first in 31% of games, 14th-most in MLB, 29% against right-handers.


Sandy Alcantara has kept the first inning clean in 85% of his 27 starts, and Cade Cavalli isn't far behind at 78% — both are riding a 5-for-5 stretch over their last five outings. The pushback comes from Washington's bats, which put a run on the board in the first 32% of the time, seventh-most in the majors, in a Nationals Park that plays slightly hitter-friendly at 102. Model lands at 53% scoreless, a hair under the book's 55%.
- NRFI lean — Sandy Alcantara (85% NRFI) and Cade Cavalli (78%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -145 (55% implied); the model has it 53%.
- The Washington Nationals score in the first in 32% of games, 7th-most in MLB, 31% against right-handers.
- The Miami Marlins score in the first in 29% of games, 17th-most in MLB, 31% against right-handers.


Merrill Kelly has kept the first inning clean in 67% of his 24 starts, including four of his last five, and he's facing a Giants lineup that scores in the opening frame just 25% of the time — 21% against righties. Matt Wilkinson is 2-for-2 in scoreless firsts, though two starts tells you very little. Oracle Park's 94 run factor nudges things further toward NRFI, hence the modest 54% read.
- NRFI lean — Merrill Kelly has worked a scoreless first in 67% of his starts, the headline edge in a quiet matchup.
- Books price this NRFI at -121.5 (52% implied); the model has it 54%.

- The Arizona Diamondbacks score in the first in 30% of games, 16th-most in MLB, 27% against left-handers.


Foster Griffin has kept the first inning clean in 80% of his 25 starts, and that's the backbone of the lean here — Kansas City puts a run on the board in the opening frame 31% of the time, but Griffin's track record blunts that. On the other side, Daniel Lynch IV is the wobblier half at 50% NRFI across just four starts, though Cleveland's bats only strike first 27% of the time (25% against lefties). Progressive Field's 94 run factor nudges it further toward quiet, hence the modest 54% scoreless read against a market at 52%.
- NRFI lean — Foster Griffin has worked a scoreless first in 80% of his starts, the headline edge in a quiet matchup.
- Books price this NRFI at -125 (52% implied); the model has it 54%.
- The Cleveland Guardians score in the first in 27% of games, 22nd-most in MLB, 25% against left-handers.
- The Kansas City Royals score in the first in 31% of games, 10th-most in MLB, 32% against left-handers.


Walker Buehler and Nick Martinez both sit above 80% NRFI on the season — 81% across 26 starts for Buehler, 83% over 24 for Martinez — which is a tough combination to score against early. San Diego's offense compounds it, plating a first-inning run in just 23% of games and 20% against righties. Tropicana Field's 95 run factor nudges the model to 57%, ahead of the market's 51%.
- NRFI lean — Walker Buehler (81% NRFI) and Nick Martinez (83%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -116.5 (51% implied); the model has it 57%.
- The Tampa Bay Rays score in the first in 32% of games, 9th-most in MLB, 30% against right-handers.
- The San Diego Padres score in the first in 23% of games, 29th-most in MLB, 20% against right-handers.


Max Fried has kept the first inning clean in 71% of his 14 starts, and he's facing a Red Sox offense that plates a run in the opening frame just 24% of the time — 28th in MLB, with no bump against lefties. The counterweight is Alec Gamboa, who owns a spotless first-inning mark but across exactly one start, so there's little to lean on. The model's 54% sits just under the book's 56%, making this a mild NRFI tilt rather than a strong one.
- NRFI lean — Max Fried has worked a scoreless first in 71% of his starts, the headline edge in a quiet matchup.
- Books price this NRFI at -146 (56% implied); the model has it 54%.
- The New York Yankees score in the first in 28% of games, 19th-most in MLB, 35% against left-handers.
- The Boston Red Sox score in the first in 24% of games, 28th-most in MLB, 24% against left-handers.


Cal Quantrill has kept the first inning clean in nine of 10 starts this year, including all five of his last five, and Shane Drohan isn't far behind at 87% across 15 outings. Neither offense pushes early either — Texas and Milwaukee both plate a first-inning run in just 28% of games, and the Rangers dip to 22% against lefties. American Family Field's 94 run factor nudges it further toward zeros.
- NRFI lean — Cal Quantrill (90% NRFI) and Shane Drohan (87%) have both buried the first inning, and neither lineup gets going early.
- Books price this NRFI at -118 (51% implied); the model has it 57%.
- The Milwaukee Brewers score in the first in 28% of games, 20th-most in MLB, 26% against right-handers.
- The Texas Rangers score in the first in 28% of games, 21st-most in MLB, 22% against left-handers.

- Books price this NRFI at -128 (53% implied); the model has it 54%.
- The San Francisco Giants score in the first in 25% of games, 27th-most in MLB, 22% against left-handers.

Erick Fedde has kept the first inning clean in just 42% of his 12 starts, and he's walking into Target Field (104 run factor) against a Twins lineup that puts a run on the board in the opening frame 35% of the time — second-most in baseball. That's the engine behind the YRFI lean. Bailey Ober is the counterweight at 74% NRFI, which is why the model still gives a scoreless first a 44% shot.
- YRFI lean — the Minnesota Twins push a first-inning run across in 35% of games (2nd-most in MLB), hard to keep off the board early.
- Books price this NRFI at -0.5 (1% implied); the model has it 44%.
- The Minnesota Twins score in the first in 35% of games, 2nd-most in MLB, 35% against right-handers.
- The Chicago White Sox score in the first in 32% of games, 8th-most in MLB, 30% against right-handers.


Sutter Health Park's 117 run factor is doing most of the heavy lifting here, because neither offense has been especially quick out of the gate — Oakland plates a first-inning run in 28% of games, Baltimore just 25%. Shane Baz has kept the first clean in 64% of his 25 starts, and Jack Perkins sits at 55%, so the modest YRFI lean is really a ballpark story more than a pitching one.
- YRFI lean — Sutter Health Park (run factor 117) is one of the league's most hitter-friendly parks, and the Oakland Athletics score early in 28% of games.
- Books price this NRFI at -1 (2% implied); the model has it 46%.
- The Oakland Athletics score in the first in 28% of games, 18th-most in MLB, 28% against right-handers.
- The Baltimore Orioles score in the first in 25% of games, 26th-most in MLB, 31% against right-handers.

Keider Montero has kept the first inning clean in 86% of his 21 starts, easily the strongest number on the board here, and Blake Snell counters at 75% across his four. The tension comes from Detroit's bats, which put up a run in the opening frame 33% of the time — fourth-most in MLB — though only 30% against lefties. At 51% scoreless in the model versus 52% implied, Comerica gives no real tilt either way.
- Coin flip — Keider Montero's 86% NRFI is the case for the under; the Detroit Tigers' 33% first-inning bats (4th-most in MLB) are the case for the over.
- Books price this NRFI at -127 (52% implied); the model has it 51%.
- The Detroit Tigers score in the first in 33% of games, 4th-most in MLB, 30% against left-handers.
- The Los Angeles Dodgers score in the first in 31% of games, 11th-most in MLB, 32% against right-handers.


Kyle Leahy has kept the first inning clean in 88% of his 24 starts and is 5-for-5 in his last five, which is the sturdiest number on the board. The pushback comes from Lake Bachar, who sits at 67% NRFI across just six starts, and a Pirates lineup that plates a first-inning run 34% of the time against righties. Neutral Busch Stadium leaves this near a true 52% split.
- Coin flip — Kyle Leahy's 88% NRFI is the case for the under; the St. Louis Cardinals' 31% first-inning bats (12th-most in MLB) are the case for the over.
- Books price this NRFI at -120 (52% implied); the model has it 52%.
- The St. Louis Cardinals score in the first in 31% of games, 12th-most in MLB, 25% against right-handers.
- The Pittsburgh Pirates score in the first in 30% of games, 15th-most in MLB, 34% against right-handers.


Andrew Abbott's 58% first-inning shutout rate across 26 starts is the soft spot here — modest for a pitcher opposing Kevin Gausman, who's held the zero in 65% of his starts and four of his last five. Both offenses are quiet early, with the Cubs and Reds each plating a first-inning run in just 26% of games, and Wrigley's 94 run factor trims the margins further. Still, the model's 52% scoreless read sits well under the market's 64%, making this closer to a toss-up than the price suggests.
- Coin flip — Kevin Gausman's 65% NRFI is the case for the under; the Cincinnati Reds' 26% first-inning bats (24th-most in MLB) are the case for the over.
- Books price this NRFI at +1.5 (64% implied); the model has it 52%.
- The Chicago Cubs score in the first in 26% of games, 23rd-most in MLB, 25% against left-handers.
- The Cincinnati Reds score in the first in 26% of games, 24th-most in MLB, 28% against right-handers.


Martin Perez has kept the first frame clean in 71% of his 21 starts, four of five most recently — comfortably the sturdiest number on this card. Working against that, Zach Agnos offers only two starts to judge, and Colorado puts a run on the board in the opening inning 32% of the time, 37% against lefties. With Truist Park carrying a 102 run factor, 48% scoreless is a true coin flip.
- Coin flip — Martin Perez's 71% NRFI is the case for the under; the Colorado Rockies' 32% first-inning bats (6th-most in MLB) are the case for the over.
- Books price this NRFI at 0 (0% implied); the model has it 48%.
- The Atlanta Braves score in the first in 31% of games, 13th-most in MLB, 31% against right-handers.
- The Colorado Rockies score in the first in 32% of games, 6th-most in MLB, 37% against left-handers.


Nolan McLean has kept the first inning clean in 76% of his 25 starts, including four of his last five, and he'll need that against a Houston lineup that plates a run in the opening frame 34% of the time — third-most in MLB and 36% against righties. The wild card is Bennett Sousa, who has no starts on the season, so the Mets' quiet 26% first-inning rate is the only read there. Model and book agree at 52% NRFI, and pitcher-friendly Citi Field (94 park factor) doesn't tip it either way.
- Coin flip — Nolan McLean's 76% 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 -125 (52% implied); the model has it 52%.
- The New York Mets score in the first in 26% of games, 25th-most in MLB, 26% against left-handers.
- The Houston Astros score in the first in 34% of games, 3rd-most in MLB, 36% against right-handers.


Cristopher Sanchez has kept the first inning clean in 76% of his 25 starts, and Ryan Johnson counters at 75% over his 12 — both with four scoreless openers in their last five. The tension comes from the bats: the Angels put up a first-inning run in 35% of games, most in MLB, and the Phillies rank fifth at 33%. At 47% scoreless in a slightly run-friendly Angel Stadium, it's genuinely even.
- Coin flip — Cristopher Sanchez's 76% NRFI is the case for the under; the Los Angeles Angels' 35% first-inning bats (most in MLB) are the case for the over.
- Books price this NRFI at -114 (50% implied); the model has it 47%.
- The Los Angeles Angels score in the first in 35% of games, the most in MLB, 38% against left-handers.
- The Philadelphia Phillies score in the first in 33% of games, 5th-most in MLB, 28% against right-handers.
