NYY 1st: 28% (#20) · 24% vs hand

Cam Schlittler has kept the first inning clean in 86% of his 29 starts and is a perfect 5-for-5 in his last five, which is the anchor here. Christian Scott brings a solid 76% NRFI mark of his own, and neither offense does much early — the Yankees plate a first-inning run in just 28% of games, the Mets 29%. The model's 55% barely nudges the book's 54%.

  • NRFI lean — Christian Scott (76% NRFI) and Cam Schlittler (86%) have both buried the first inning, and neither lineup gets going early.

Trevor Rogers has kept the first inning clean in 88% of his 26 starts, including each of his last five, and he's facing a Toronto lineup that plates a first-inning run just 24% of the time — 29th in MLB, and only 20% against lefties. Dylan Cease is the softer side at 65%, but Baltimore's bats rank 27th in first-inning scoring. Model and market agree at 57-58% NRFI.

Chase Burns has kept the first inning clean in 85% of his 26 starts, an elite mark that anchors this lean toward NRFI — though he's slipped to 3-of-5 lately against a Milwaukee lineup that plates a first-inning run 31% of the time, 10th-most in MLB. On the other side, Robert Gasser (65% NRFI) draws a Reds club scoring in the opening frame just 18% against lefties, and American Family Field's 94 run factor trims the margins further.

Matthew Boyd has kept the first inning clean in 78% of his 18 starts, and the Pirates have been especially quiet against lefties, plating a first-inning run just 18% of the time. Bubba Chandler matches up well too at 74% NRFI, with Wrigley's 94 run factor trimming the margins further. Still, the model's 54% sits just under the book's 55%, so the lean is mild rather than emphatic.

Nick Pivetta hasn't allowed a first-inning run in any of his four starts, and he's drawing a Giants lineup that pushes across a run in the opening frame just 29% of the time — 23% against righties. Logan Webb's 80% first-inning clean rate over 25 starts stacks up well against a Padres offense that ranks dead last in first-inning scoring at 24%. Oracle Park's 94 run factor tilts it further toward zeros, though the model's 57% is barely ahead of the market's 56%.

Jackson Jobe has kept the first inning clean in just 33% of his six starts, and only once in his last five — a shaky foundation against a Rockies lineup that plates a first-inning run in 31% of games. On the other side, Gabriel Hughes sits at 45% NRFI while facing a Detroit offense that scores in the opening frame 34% of the time, second-most in MLB. Comerica's neutral park factor does little to cool that off, and the model's 44% scoreless read runs a touch under the book's 48%.

Fourth-most first-inning scoring in the majors belongs to the Angels, who put a run up in 34% of their games and 33% against righties — exactly the kind of bat that tests Jake Irvin, whose 61% NRFI rate over 18 starts is solid but not airtight. Grayson Rodriguez has been the steadier of the two at 65%, though Nationals Park's 102 run factor nudges things toward the YRFI side at a 46% scoreless projection.

Grant Holmes has kept the first inning clean in 88% of his 25 starts, including each of his last five — that's the anchor here. The problem is the other side: Andrew Painter sits at 65% and has been shaky lately at 3-of-5, and the Phillies rank sixth in MLB at scoring in the opening frame. With Truist Park playing a tick above average at 102, the model's 51% scoreless read is genuinely a toss-up, modestly above the 45% the book implies.

Hayden Wesneski has kept the first inning clean in 88% of his eight starts, including each of his last five — that's the strongest single number on the board. The problem is what's on the other side: Freddy Peralta has surrendered a first-inning run in three of his last five, and Houston's bats rank third in MLB at scoring in the opening frame (35% against righties). Tropicana Field's 95 run factor helps, but the model's 49% scoreless sits essentially even with the book's 51%.

Eury Perez has kept the first inning clean in 68% of his 25 starts, and that's the sturdiest number on the board here. The problem is the other side: Emmet Sheehan sits at 55% for the season and just 2-of-5 lately, and he's facing a Dodgers-caliber opponent in a Marlins lineup that plates a first-inning run 29% of the time against righties. Model says 47% scoreless, book implies 36% — genuine disagreement on a true toss-up.

Noah Cameron's 81% first-inning shutout rate across 27 starts is the sturdiest number on the board, and he draws a Boston offense that plates a run in the opening frame just 25% of the time — 28th in MLB. The pushback comes from the other side: Fenway plays 8% above average for runs, and Kansas City's bats rank fifth in first-inning scoring at 32% against a 67% NRFI arm in Payton Tolle.
