Kyle Bradish has kept the first frame clean in 90% of his 20 starts, including all five of his last five, and Zack Wheeler brings his own 82% NRFI rate to Camden Yards. Baltimore's bats have plated a first-inning run in just 24% of games, so the Phillies' hotter lineup is the main reason this only nudges toward a scoreless opening.

NYM 1st: 26% (#23) · 22% vs hand

Sandy Alcantara has been airtight early this season, posting an 82% NRFI mark across 22 starts and holding the line in each of his last five outings. That pairs nicely against a Mets lineup that scores in the first just 26% of the time, and only 22% against righties. The unknown with Robert Stock's debut keeps confidence in check, but the lean sits with NRFI at Citi Field.

Colin Rea has been airtight to start games, posting a 78% NRFI mark across 18 starts and holding the line in each of his last five. Gerrit Cole matches that with a 75% first-inning shutout rate and four scoreless openers in his last five. With the Cubs plating a first-inning run just 25% of the time and Wrigley's below-average run factor, the scoreless lean makes sense.

Kyle Hart is a perfect 3-for-3 on NRFI in his brief three-start sample, and Landen Roupp brings an 81% first-inning zero rate across 21 outings — a strong duo backed by two sluggish offenses. The Giants and Padres rank near the MLB bottom in first-inning scoring (22% and 23%), and Petco's 94 run factor only tilts things further toward a scoreless frame.

HOU 1st: 35% (#2) · 39% vs hand

Kumar Rocker's first-inning wobble is the story here — just 44% NRFI over 18 starts, and he's coughed up a first-inning run in four of his last five. That plays right into a Houston lineup that scores in the opening frame 39% of the time against righties, second-most in MLB. Peter Lambert's strong 83% NRFI keeps the Rangers side quiet, but Rocker's end nudges this toward YRFI.

Coors Field and its 128 run factor set the tone here, and the model gives just a 37% chance of a scoreless first. Neither Seth Lugo (52% NRFI) nor Kyle Freeland (61%) offers much of a firewall, and Colorado's bats plate a first-inning run 34% of the time — fifth-most in the majors. That combination nudges this one toward YRFI.

Cade Cavalli brings a tidy 73% first-inning scoreless rate into Truist Park, but his last five have all come up clean, and JR Ritchie sits close behind at 71%. Both offenses cut against those arms, though — Washington scores in the opening frame 34% of the time (4th-most in MLB) and Atlanta 32% — which is why this one grades out as a near-even 47%.

Toronto's offense is the tension-breaker here, plating a first-inning run in just 22% of games and only 15% against lefties like Matthew Liberatore, who carries a 55% NRFI rate. Max Scherzer's shakier 43% first-inning scoreless mark keeps this even, though, especially with the Cardinals scoring early 25% of the time versus righties. The model's 49% edge over the book's 48% barely tips the scale.

Gavin Williams brings the sharpest first-inning résumé here, posting a 71% NRFI rate across 21 starts, while Merrill Kelly counters at 63%. Cleveland's offense rarely gets going early, scoring in the first just 25% of the time, though Arizona's bats are slightly livelier at 31%. With Progressive Field's 94 run factor suppressing scoring, the model and market land in step at 53% NRFI.

Griffin Jax brings a strong 76% NRFI mark across 17 starts into Tropicana Field, and Anthony Kay isn't far behind at 68% with five straight clean first innings. Neither lineup does much early — the White Sox plate a first-inning run just 24% of the time against lefties. Still, the model sits at 50%, a touch under the book's 53%, so this reads as a genuine coin flip.

Chase Burns has been a first-inning wall in Cincinnati, posting an 89% NRFI mark across 19 starts, and the Reds themselves plate a run in the opening frame just 27% of the time. Working against that is Great American's hitter-friendly 106 park factor and a Pirates lineup that scores early 37% of the time versus righties, keeping this one squarely a coin flip.

Both starters own elite first-inning numbers, with Walbert Urena stretching a perfect 5-for-5 NRFI over his last five and sitting at 88% on the year, while Jacob Misiorowski checks in at 84%. The tension comes from the Angels' bats, who plate a first-inning run in a league-high 36% of games. That clash lands this one at a genuine coin flip, with the model's 52% just shy of the book's 57%.

Two strong first-inning arms clash here: Keider Montero's 88% NRFI rate across 17 starts and Gage Jump's 83% over 12 give this a scoreless tilt. What keeps it from a clean lean is Sutter Health Park's hefty 117 run factor, plus Detroit's lineup that puts up a first-inning run 33% of the time. The model's 48% scoreless leaves it a genuine coin flip.
