Miami Marlins at San Diego Padres
Sandy Alcantara (RHP): 84% NRFI, 3.84 ERA, 1.23 WHIP, 6.5 K/9, 2.5 BB/9, NRFI streak of 1. Walker Buehler (RHP): 80% NRFI, 4.58 ERA, 1.37 WHIP, 7.7 K/9, 3.4 BB/9, NRFI streak of 3. First pitch 4:10 PM ET at Petco Park (15 ft).
Sandy Alcantara anchors this one at 84% NRFI, and the combined 70% rate keeps the game in play as a lean. Walker Buehler holds up his end too, a 80% scoreless rate that only needs to match the moment. The pressure point is the Miami Marlins lineup, which has handled RHP well this year at a .755 OPS in that split, so Walker Buehler cannot afford a sloppy first. NRFI projects clean here.
New York Yankees at Arizona Diamondbacks
Will Warren (RHP): 71% NRFI, 3.89 ERA, 1.36 WHIP, 8.9 K/9, 3.1 BB/9, NRFI streak of 4. Corbin Burnes (RHP): 100% NRFI, 5.87 ERA, 1.17 WHIP, 7.5 K/9, 2.5 BB/9, NRFI streak of 2. First pitch 4:10 PM ET at Chase Field, indoor.
Corbin Burnes is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. Will Warren is the softer side at 71% NRFI, but he only has to be ordinary in the first for this to cash. We will take NRFI here, a lean rather than a lock.

Philadelphia Phillies at New York Mets
Cristopher Sánchez (LHP): 77% NRFI, 2.93 ERA, 1.22 WHIP, 10.0 K/9, 2.0 BB/9. Jonah Tong (RHP): 100% NRFI, 3.43 ERA, 1.19 WHIP, 8.6 K/9, 3.9 BB/9, NRFI streak of 2. First pitch 1:10 PM ET at Citi Field (20 ft).
Jonah Tong is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. On the other side, Cristopher Sánchez is no pushover either at 77% NRFI, so this does not lean on one arm alone. The pressure point is the Philadelphia Phillies lineup, which has handled RHP well this year at a .751 OPS in that split, so Jonah Tong cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock.
Honorable Mentions
- Toronto Blue Jays at Texas Rangers: Spencer Miles riding a run of 7 scoreless first innings.
- Boston Red Sox at Tampa Bay Rays: Patrick Sandoval riding a run of 4 scoreless first innings.
- Kansas City Royals at Pittsburgh Pirates: Lake Bachar riding a run of 4 scoreless first innings.
Games to Avoid
These matchups carry the highest first inning scoring risk on tonight's slate.
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. We are passing here.
Chicago Cubs at Cincinnati Reds. David Peterson has not shown the early command to trust, a 4.1 BB/9 that invites first inning traffic. This is a spot to skip.
Minnesota Twins at Los Angeles Angels. Dean Kremer's 5.35 ERA tells the story, vulnerable early and often. This is a spot to skip.

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.
