New York Yankees at Arizona Diamondbacks
Cam Schlittler (RHP): 87% NRFI, 1.95 ERA, 0.90 WHIP, 11.1 K/9, 2.1 BB/9, NRFI streak of 7. Brandon Pfaadt (RHP): 82% NRFI, 3.77 ERA, 1.17 WHIP, 6.1 K/9, 2.1 BB/9, NRFI streak of 4. First pitch 8:10 PM ET at Chase Field, indoor.
This is the kind of matchup NRFI bettors circle. Cam Schlittler (87% NRFI) and Brandon Pfaadt (82%) both clear the bar comfortably, and the 71% combined rate is the proof. Cam Schlittler is trending up as well, a 0.84 ERA across his last five starts against a 1.95 season mark. The pressure point is the Arizona Diamondbacks lineup, which has handled RHP well this year at a .741 OPS in that split, so Cam Schlittler cannot afford a sloppy first. NRFI projects clean here.
Toronto Blue Jays at Texas Rangers
José Soriano (RHP): 80% NRFI, 3.56 ERA, 1.27 WHIP, 8.5 K/9, 3.8 BB/9, NRFI streak of 17. Cal Quantrill (RHP): 86% NRFI, 2.90 ERA, 1.05 WHIP, 6.7 K/9, 2.1 BB/9, NRFI streak of 3. First pitch 7:05 PM ET at Globe Life Field, indoor.
Cal Quantrill is the reason to look here, a 86% scoreless rate in the first that carries most of the weight for this lean. José Soriano holds up his end too, a 80% scoreless rate that only needs to match the moment. Cal Quantrill is trending up as well, a 2.32 ERA across his last five starts against a 2.90 season mark. The loose thread is José Soriano's 3.8 BB/9; an early walk is how this inning gets away. We will take NRFI here, a lean rather than a lock.

Miami Marlins at San Diego Padres
Eury Pérez (RHP): 70% NRFI, 3.99 ERA, 1.24 WHIP, 9.7 K/9, 4.0 BB/9, NRFI streak of 1. Casey Mize (RHP): 92% NRFI, 3.69 ERA, 1.14 WHIP, 7.8 K/9, 2.2 BB/9. First pitch 8:40 PM ET at Petco Park (15 ft).
Casey Mize is the reason to look here, a 92% scoreless rate in the first that carries most of the weight for this lean. Eury Pérez is the softer side at 70% NRFI, but he only has to be ordinary in the first for this to cash. Casey Mize's 2.2 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Miami Marlins lineup, which has handled RHP well this year at a .752 OPS in that split, so Casey Mize cannot afford a sloppy first. The loose thread is Eury Pérez's 4.0 BB/9; an early walk is how this inning gets away. We will take NRFI here, a lean rather than a lock.
Honorable Mentions
- Washington Nationals at St. Louis Cardinals: Andrew Alvarez riding a run of 15 scoreless first innings.
- Athletics at Cleveland Guardians: Tanner Bibee riding a run of 12 scoreless first innings.
- Milwaukee Brewers at Baltimore Orioles: Trevor Rogers riding a run of 19 scoreless first innings.
Games to Avoid
These matchups carry the highest first inning scoring risk on tonight's slate.
Detroit Tigers at Chicago White Sox. Jackson Jobe has surrendered a run in the first in 3 straight starts, and that trend matters more than the 29% season rate. Leave this one alone.
Seattle Mariners at Colorado Rockies. Coors does what Coors does. At 5,200 feet the ball carries, and even the better arm here gives back margin in the first. Not a first inning to trust.
Boston Red Sox at Tampa Bay Rays. Brayan Bello is the weak link at 44% NRFI, and the combined 36% rate sits near the bottom of the slate. Leave this one alone.

Before You Lock
Confirm the starting pitchers on the NRFI dashboard. A bullpen game kills NRFI value immediately. Check the weather at first pitch and be careful at altitude, Coors in particular. NRFI bets land 55% to 65% of the time historically, and you need roughly 52.4% to break even at minus 110 odds.
