Miami Marlins at Arizona Diamondbacks
Sandy Alcantara (RHP): 84% NRFI, 3.78 ERA, 1.22 WHIP, 6.4 K/9, 2.5 BB/9. Corbin Burnes (RHP): 100% NRFI, 0.00 ERA, 1.33 WHIP, 6.0 K/9, 6.0 BB/9, NRFI streak of 1. First pitch 9:40 PM ET at Chase Field, indoor.
This is the kind of matchup NRFI bettors circle. Sandy Alcantara (84% NRFI) and Corbin Burnes (100%) both clear the bar comfortably, and the 67% combined rate is the proof. The pressure point is the Miami Marlins lineup, which has handled RHP well this year at a .757 OPS in that split, so Corbin Burnes cannot afford a sloppy first. The lean is NRFI, carried by the stronger arm.
Chicago White Sox at Cleveland Guardians
Sean Newcomb (LHP): 100% NRFI, 2.77 ERA, 1.14 WHIP, 8.3 K/9, 3.2 BB/9, NRFI streak of 5. Gavin Williams (RHP): 72% NRFI, 3.78 ERA, 1.09 WHIP, 12.1 K/9, 2.8 BB/9. First pitch 6:40 PM ET at Progressive Field (660 ft).
Sean Newcomb is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. Gavin Williams is the softer side at 72% NRFI, but he only has to be ordinary in the first for this to cash. Sean Newcomb is trending up as well, a 0.98 ERA across his last five starts against a 2.77 season mark. We will take NRFI here, a lean rather than a lock.

San Francisco Giants at St. Louis Cardinals
Landen Roupp (RHP): 82% NRFI, 4.00 ERA, 1.28 WHIP, 8.3 K/9, 4.3 BB/9, NRFI streak of 3. Quinn Mathews (LHP): 67% NRFI, 4.11 ERA, 1.50 WHIP, 8.3 K/9, 4.2 BB/9. First pitch 7:45 PM ET at Busch Stadium (455 ft).
Landen Roupp anchors this one at 82% NRFI, and the combined 55% rate keeps the game in play as a lean. Quinn Mathews is the softer side at 67% NRFI, but he only has to be ordinary in the first for this to cash. Landen Roupp is trending up as well, a 3.08 ERA across his last five starts against a 4.00 season mark. It helps that the San Francisco Giants lineup has been quiet against LHP this year at a .577 OPS, which gives Quinn Mathews margin in the opening frame. The loose thread is Quinn Mathews's 4.2 BB/9; an early walk is how this inning gets away. There is a small NRFI edge, nothing more, so size it lightly.
Honorable Mentions
- Baltimore Orioles at New York Mets: Jonah Tong sitting at 100% NRFI.
- Seattle Mariners at Los Angeles Angels: Reid Detmers riding a run of 7 scoreless first innings.
- Detroit Tigers at Toronto Blue Jays: José Soriano riding a run of 16 scoreless first innings.
Games to Avoid
These matchups carry the highest first inning scoring risk on tonight's slate.
Atlanta Braves at Chicago Cubs. Reynaldo López is the weak link at 42% NRFI, and the combined 24% rate sits near the bottom of the slate. Leave this one alone.
New York Yankees at Minnesota Twins. Dean Kremer's 5.65 ERA tells the story, vulnerable early and often. We are passing here.
San Diego Padres 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. 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.
