PHI 1st: 33% (#5) · 28% vs hand

Jesus Luzardo has kept the first inning clean in 93% of his 27 starts, and Grant Holmes isn't far behind at 88% with five straight scoreless openers. That matters because Philadelphia's bats, despite ranking fifth in MLB for first-inning scoring at 33%, dip to 28% against left-handers — er, against Holmes' right-handed look they've been solid, but Atlanta's offense scores early just 24% of the time versus southpaws. Citizens Bank Park's 102 run factor is the main counterweight.

Trevor Rogers has kept the first inning clean in 88% of his 25 starts, including all five of his last five, and he's facing a Cleveland offense that plates a first-inning run just 27% of the time (24% against lefties). Baltimore's bats have been even quieter early — 26% overall, 16% versus left-handers, which is where Joey Cantillo comes in despite an 0-for-5 stretch. Camden Yards plays neutral, and the model's 56% sits just past the book's 54%.

Matthew Boyd has kept the first inning clean in 76% of his 17 starts, and four of his last five, which anchors the modest NRFI lean at American Family Field's run-suppressing 94 park factor. Robert Gasser's 63% clip is solid but shakier, and Milwaukee's lineup jumps to 37% first-inning scoring against lefties. The model's 53% barely separates from the book's 52% — a thin edge either way.

Nick Pivetta hasn't allowed a first-inning run in any of his three starts, and Petco Park's 94 run factor gives him a friendly backdrop against a Washington lineup that scores in the opening frame just 30% of the time. Jake Irvin brings a 65% NRFI mark of his own, facing a Padres offense that ranks 30th in first-inning scoring at 24%. The model's 54% edges the market's 51%.

Logan Webb has kept the first inning clean in 79% of his 24 starts, and Michael McGreevy isn't far behind at 76% across 25 — two righties who tend to settle in early at a pitcher-friendly Oracle Park (94 run factor). San Francisco's bats have only dented the first frame in 26% of games, 21% against righties. The model sits at 56% scoreless, well shy of the book's 98% implied number.

BOS 1st: 26% (#27) · 25% vs hand

Brayan Bello has kept the first inning clean in just 38% of his eight starts, and only one of his last five — a rough draw against an Angels lineup that plates a run in the opening frame 34% of the time, third-most in MLB. Grayson Rodriguez's 63% NRFI rate offers some balance, but with Fenway's 108 park factor, the model's 44% scoreless sits under the book's implied 51%.

Fenway Park · park run factor 108

DET 1st: 34% (#4) · 34% vs hand

Minnesota's bats put up first-inning runs in 36% of games — the highest rate in MLB — and 38% against right-handers like Troy Melton, whose 65% NRFI mark across 17 starts leaves room for trouble. Detroit isn't far behind at 34%, fourth-most in the league, and Joe Ryan's 68% clip has slipped to 3-of-5 recently. Two aggressive early-inning offenses at a neutral Comerica Park tilts this toward YRFI.

Eury Perez has kept the first inning clean in 71% of his 24 starts, including four of his last five — that's the one firm data point here. The problem is the other side: Jonah Tong hasn't started a game this season, so the Mets' half is guesswork, and both offenses hover near league average in first-inning scoring (Miami 29%, New York 28%). Model and market agree at 51% scoreless.

Noah Cameron has kept the first inning clean in 81% of his 26 starts, including four of his last five — that's the anchor here. The problem is the other half: Derek Law hasn't started a game this season, so there's no first-inning track record to lean on against a Kansas City lineup that scores in the opening frame 33% of the time, sixth-most in MLB. With Kauffman playing slightly above average at a 102 run factor, the model lands right at 50% scoreless.

Jacob Lopez has kept the first inning clean in 84% of his 19 starts, and Dylan Cease sits at 68% across 25 — numbers that pair nicely with two offenses that rarely strike early, Toronto scoring in the first just 24% of the time (29th in MLB) and Oakland 28%. Yet Sutter Health Park's 117 run factor pulls the other way, and the model lands right at 50%, a touch under the book's 55% NRFI.
