TOR 1st: 22% (#29) · 19% vs hand

Patrick Sandoval hasn't allowed a first-inning run in any of his five starts, and he draws a Toronto lineup that scores in the opening frame just 22% of the time — and only 19% against lefties. Dylan Cease adds to the NRFI case with a 65% clean-first rate and five straight scoreless first innings. Both offenses rank near the bottom in early scoring.

Rogers Centre · park run factor 100
  • NRFI lean — Patrick Sandoval (100% NRFI) and Dylan Cease (65%) have both buried the first inning, and neither lineup gets going early.
  • Books price this NRFI at -157 (57% implied); the model has it 55%.

Both aces are locking down early frames, with Walker Buehler riding a 5-for-5 clean-first streak and Kyle Harrison sporting an 82% NRFI mark across 17 starts. San Diego's bats have been sluggish out of the gate, plating a first-inning run in just 24% of games, and pitcher-friendly Petco (94 park factor) only reinforces the scoreless lean here.

Hunter Brown's 80% first-inning NRFI rate over 10 starts anchors this lean, and he draws a soft matchup in a Giants lineup that scores in the opening frame just 22% of the time — 30th in MLB, and only 18% against righties. Oracle Park's pitcher-friendly 94 run factor helps too. The model's 54% edges the book's 51%.

Colorado's bats are the concern here — they've plated a first-inning run in 35% of games, second-most in MLB, and 36% against lefties like Mitch Bratt. Sugano hasn't helped his own cause lately, holding a first-inning zero in just two of his last five starts. Add in Chase Field's 106 run factor, and the model's 44% scoreless figure tilts toward YRFI.

Sutter Health Park inflates offense (117 run factor), and that's the biggest reason this leans YRFI despite a strong arm on the mound. Nick Martinez has been excellent early for the Rays at 86% NRFI across 21 starts, but Mason Barnett's two-start sample offers little to trust, and Tampa Bay's lineup scores in the first 33% of the time. Just a slight edge over the market.

Drew Anderson has yet to allow a first-inning run across his three MLB starts, while Bibee brings a 74% NRFI rate and a clean 5-for-5 in his last five. The counterweight is Detroit's bats, who score in the first 34% of the time — 4th-most in the league — against a Cleveland offense that ranks near the bottom. Anderson's tiny sample keeps this a true coin flip at 51%.

Skenes brings a 74% first-inning shutout rate into loanDepot park and has kept the board clean in four of his last five, while Eury Perez counters with five straight scoreless first innings. The two offenses barely register early — Miami plates a run in the first just 30% of the time, Pittsburgh 31% — yet the model's 49% scoreless read trails the book's 59%, leaving this closer to a toss-up than the arms suggest.

Shota Imanaga's 77% NRFI mark, including four clean first innings over his last five starts, is the strongest lean toward a quiet frame here. The tension is Washington's bats, which score in the opening inning 34% of the time — third-most in MLB — though that dips to 31% against lefties. With Jake Irvin at a middling 58% NRFI, the model settles at a true 49% toss-up.

Bryan Woo brings the sharper first-inning résumé here, posting an 81% NRFI mark across 21 starts, and the Yankees have plated a first-inning run in just 24% of games against righties. Ryan Weathers has been steady too at 64%, but the Mariners crack the board 30% of the time versus lefties. That two-sided pressure keeps this one close to a coin flip at 51%.

Nearly identical NRFI resumes on the mound make this one a genuine tossup: Nolan McLean sits at 73% over 22 starts, Martin Perez at 72% across 18. Neither offense pushes the needle either, with Atlanta plating a first-inning run 31% of the time and the Mets just 27%. The model's 51% edges the book by a single point — a true coin flip.

Bailey Ober brings the best first-frame résumé here, sitting scoreless in 75% of his 16 starts, and Brandon Young's 68% NRFI rate isn't far behind. The Orioles' bats work against him — Baltimore plots a first-inning run just 24% of the time, 27th in MLB. Even so, Target Field's 104 run factor and Minnesota's above-average 33% first-inning strike rate keep this a genuine coin flip.

Nick Lodolo brings the sharpest arm to Rate Field, sitting on an 83% first-inning scoreless rate with five straight clean openers, and Sean Burke's 72% mark isn't far behind. The reason this stays a coin flip: Chicago's bats push a run across in the first 31% of the time, keeping the White Sox lively enough to offset those strong starters.

Cristopher Sanchez brings a 77% NRFI mark into Busch Stadium and has held the line in four of his last five starts, while Andre Pallante has gone a perfect 5-for-5 to keep his season figure at 68%. Both offenses stay quiet early, with the Cardinals scoring first just 30% of the time and dropping to 33% against lefties.

The catch is Blake Snell, whose 0% NRFI mark comes from a single start, so there's really no read on him. That thin sample is why this one grades as a genuine coin flip.
