Joey Cantillo is the anchor here, holding a scoreless first in 82% of his 22 starts and clean in all five of his last five. Cleveland's bats haven't helped anyone crack the first inning much either, scoring just 25% of the time — bottom-tier in MLB. Sean Manaea's 56% NRFI is shakier, but with Progressive Field's 94 park factor suppressing offense, the Mets' side leans quiet too.

Logan Henderson has kept the first inning clean in 89% of his nine starts, and he's carried a spotless zero across his last five outings. Jared Jones matches that with a 5-for-5 recent streak of his own and an 82% NRFI mark. With a pitcher-friendly park factor of 94 and Milwaukee scoring in the first just 27% of the time, this leans quietly toward NRFI.

Assad has been nearly untouchable early, posting an 89% NRFI over nine starts, and Skubal complements that with a 67% clip and a clean 5-for-5 in his last five. Neither offense hits particularly hard in the opening frame, and Wrigley's below-average 94 park factor further tilts this toward a quiet first inning.

MacKenzie Gore anchors this lean, posting a 68% NRFI mark across 22 starts and putting up scoreless first frames in three of his last five. The Giants have been quiet early too, plating a run in just 22% of their opening innings — 30th in MLB. Globe Life Field's 94 run factor tilts things further toward zeros, though Blade Tidwell's blank slate keeps confidence modest.

Emerson Hancock leads the way here, sitting on a 78% NRFI mark across 18 starts, and T-Mobile Park's run factor of 83 only tamps things down further. Detroit's offense is a real first-inning threat, ranking 5th in MLB and plating a run in 35% of games versus righties, but Melton's own 64% NRFI helps keep this leaning quiet at 55%.
- NRFI lean — Troy Melton (64% NRFI) and Emerson Hancock (78%) have both buried the first inning, and neither lineup gets going early.

Coors Field looms large here, its 128 run factor doing plenty to nudge this toward YRFI. Gabriel Hughes offers little resistance for Colorado at just a 50% first-inning scoreless rate over four starts, and the Rays plate a run in the opening frame 33% of the time. Freddy Peralta's strong 76% NRFI mark is the lone thing keeping this from tilting further.

Grayson Rodriguez brings a strong 70% first-inning NRFI mark into Camden Yards, and Baltimore's bats have been quiet early, scoring in the first just 24% of the time. The tension is on the other side: Cade Povich has posted a shaky 33% NRFI over three starts and now faces an Angels lineup that leads MLB in first-inning scoring. Those competing forces leave this one right at 49%.
- Coin flip — Grayson Rodriguez's 70% NRFI is the case for the under; the Los Angeles Angels' 36% first-inning bats (most in MLB) are the case for the over.
- Books price this NRFI at -109.5 (49% implied); the model has it 49%.
- The Baltimore Orioles score in the first in 24% of games, 27th-most in MLB, 29% against right-handers.
- The Los Angeles Angels score in the first in 36% of games, the most in MLB, 39% against left-handers.


J.T. Ginn's 79% NRFI mark over 19 starts is the standout here, and both offenses rank in the bottom third at plating a first-inning run — Cincinnati at 28%, Oakland at 28%. The catch is Brady Singer, who sits at just 53% NRFI, and Great American Ball Park's 106 run factor tilts things. That tension leaves this a genuine coin flip at 49%.
- Coin flip — J.T. Ginn's 79% NRFI is the case for the under; the Cincinnati Reds' 28% first-inning bats (20th-most in MLB) are the case for the over.
- Books price this NRFI at -114 (50% implied); the model has it 49%.

Jesus Luzardo has been nearly untouchable in the opening frame, posting a 95% NRFI over 21 starts and holding the line in each of his last five. The tension comes from the other side: Carson Palmquist sits at just 60% NRFI over five starts, and Philadelphia's bats have scored first 33% of the time. Luzardo's dominance offsets that shaky matchup, landing this squarely at a coin flip.
- Coin flip — Jesus Luzardo's 95% NRFI is the case for the under; the Washington Nationals' 35% first-inning bats (4th-most in MLB) are the case for the over.
- Books price this NRFI at -108 (49% implied); the model has it 50%.

- The Washington Nationals score in the first in 35% of games, 4th-most in MLB, 34% against left-handers.


Hunter Dobbins has kept the first frame clean in three of four starts this year, a 75% NRFI clip that gives the Cardinals a solid edge against a Yankees lineup that scores early just 33% of the time (29% versus righties). Ryan Weathers has been shakier at 62%, and with St. Louis' bats plating a first-inning run 33% against lefties, this one grades as a true toss-up.
- Coin flip — Hunter Dobbins' 75% NRFI is the case for the under; the New York Yankees' 33% first-inning bats (10th-most in MLB) are the case for the over.
- Books price this NRFI at -117 (51% implied); the model has it 48%.

- The St. Louis Cardinals score in the first in 30% of games, 16th-most in MLB, 33% against left-handers.


Sandoval has kept the first inning clean in all four of his starts, and Martin brings an 85% NRFI mark across 20 outings, so both arms tilt this scoreless. The catch is Fenway's 108 run factor and the White Sox lineup scoring first 32% of the time, enough to keep the model at a near-even 52%.
- Coin flip — Patrick Sandoval's 100% NRFI is the case for the under; the Chicago White Sox's 32% first-inning bats (13th-most in MLB) are the case for the over.
- Books price this NRFI at -120 (90% implied); the model has it 52%.

Grant Holmes has been airtight early, posting an 83% NRFI mark across 18 starts and going a perfect 5-for-5 in his last five. Ryan Gusto counters with a 75% clip and four scoreless first innings over his last five, and neither the Braves (32%) nor Marlins (31%) score in the opening frame all that often. Even at Truist Park, the arms tilt this toward a scoreless first — hence the true coin flip.
- Coin flip — Grant Holmes' 83% NRFI is the case for the under; the Atlanta Braves' 32% first-inning bats (12th-most in MLB) are the case for the over.
- Books price this NRFI at +100 (47% implied); the model has it 50%.

Randy Dobnak has kept the first inning clean in all three of his starts, and Joe Ryan brings a solid 71% NRFI mark across 21 outings — reasons this leans quiet. But the Twins are dangerous early, scoring in the first 35% of the time (2nd-most in MLB) and 36% against righties, which is why the model settles at a true 48% coin flip.
- Coin flip — Randy Dobnak's 100% NRFI is the case for the under; the Minnesota Twins' 35% first-inning bats (2nd-most in MLB) are the case for the over.

- The Minnesota Twins score in the first in 35% of games, 2nd-most in MLB, 36% against right-handers.


Trey Yesavage brings a solid 65% first-inning zeros mark over 17 starts, and he's facing a Toronto-friendly setup where the Blue Jays rank 29th in first-inning scoring at just 22%. The wild card is Hayden Wesneski, whose 0% NRFI comes from a single start — far too thin to read into. With Houston's bats scoring early 35% of the time, this one sits squarely on the fence at 50%.
- Coin flip — Trey Yesavage's 65% NRFI is the case for the under; the Houston Astros' 35% first-inning bats (3rd-most in MLB) are the case for the over.
- Books price this NRFI at -113 (50% implied); the model has it 50%.

- The Toronto Blue Jays score in the first in 22% of games, 29th-most in MLB, 25% against right-handers.


Chase Field's hitter-friendly park factor (106) is the main tension here, offsetting two steady arms who both sit around 62-63% NRFI on the season. Eduardo Rodriguez has cleaned things up lately with a scoreless first in four of his last five, and San Diego's bats rank near the bottom, plating a run in the opening frame just 23% of the time. Everything nets out to a genuine 49% coin flip.
- Coin flip — Randy Vasquez's 63% NRFI is the case for the under; the Arizona Diamondbacks' 30% first-inning bats (18th-most in MLB) are the case for the over.
- Books price this NRFI at -108 (49% implied); the model has it 49%.
- The Arizona Diamondbacks score in the first in 30% of games, 18th-most in MLB, 33% against right-handers.
- The San Diego Padres score in the first in 23% of games, 28th-most in MLB, 24% against left-handers.
