CLE 1st: 25% (#25) · 25% vs hand

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.

American Family Field · park run factor 94
  • NRFI lean — Jared Jones (82% NRFI) and Logan Henderson (89%) have both buried the first inning, and neither lineup gets going early.

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%.

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%.

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%.

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.

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.

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%.

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.

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.

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%.

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.
