## San Francisco Giants at Boston Red Sox

*Carson Whisenhunt (LHP): 57% NRFI, 7.03 ERA, 1.84 WHIP, 6.5 K/9, 5.6 BB/9. Jake Bennett (LHP): 100% NRFI, 3.46 ERA, 1.07 WHIP, 6.8 K/9, 1.9 BB/9, NRFI streak of 14. First pitch 3:15 PM ET at Fenway Park (20 ft).*

Jake Bennett is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. Carson Whisenhunt is the softer side at 57% NRFI, but he only has to be ordinary in the first for this to cash. Jake Bennett's 1.9 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Boston Red Sox lineup, which has handled LHP well this year at a .782 OPS in that split, so Carson Whisenhunt cannot afford a sloppy first. The loose thread is Carson Whisenhunt's 5.6 BB/9; an early walk is how this inning gets away. The lean is NRFI, carried by the stronger arm.

## St. Louis Cardinals at Philadelphia Phillies

*Kyle Leahy (RHP): 83% NRFI, 3.24 ERA, 1.31 WHIP, 8.2 K/9, 2.6 BB/9, NRFI streak of 10. Cristopher Sánchez (LHP): 81% NRFI, 2.51 ERA, 1.22 WHIP, 10.4 K/9, 2.1 BB/9, NRFI streak of 7. First pitch 1:35 PM ET at Citizens Bank Park (20 ft).*

Neither starter hands out early traffic, and in the first inning that is most of the battle. Kyle Leahy runs a 2.6 BB/9 and Cristopher Sánchez a 2.1 BB/9, so a walk is unlikely to spark the run this bet is fading. Cristopher Sánchez holds up his end too, a 81% scoreless rate that only needs to match the moment. Kyle Leahy is trending up as well, a 2.00 ERA across his last five starts against a 3.24 season mark. The pressure point is the Philadelphia Phillies lineup, which has handled RHP well this year at a .772 OPS in that split, so Kyle Leahy cannot afford a sloppy first. The lean is NRFI, carried by the stronger arm.

## Los Angeles Angels at Texas Rangers

*George Klassen (RHP): 80% NRFI, 3.74 ERA, 1.62 WHIP, 8.9 K/9, 7.6 BB/9, NRFI streak of 3. Cal Quantrill (RHP): 89% NRFI, 3.13 ERA, 1.15 WHIP, 6.3 K/9, 2.6 BB/9, NRFI streak of 6. First pitch 2:35 PM ET at Globe Life Field, indoor.*

Cal Quantrill is the reason to look here, a 89% scoreless rate in the first that carries most of the weight for this lean. On the other side, George Klassen is no pushover either at 80% NRFI, so this does not lean on one arm alone. Cal Quantrill arrives on a run of 6 straight scoreless first innings. The loose thread is George Klassen's 7.6 BB/9; an early walk is how this inning gets away. We will take NRFI here, a lean rather than a lock.

## Honorable Mentions

- **Toronto Blue Jays at New York Yankees:** José Soriano riding a run of 12 scoreless first innings.
- **Minnesota Twins at San Diego Padres:** a combined 61% NRFI rate.
- **Chicago Cubs at Seattle Mariners:** a combined 56% NRFI rate.

## Games to Avoid

These matchups carry the highest first inning scoring risk on tonight's slate.

**Cleveland Guardians 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. Leave this one alone.

**Cincinnati Reds at Arizona Diamondbacks.** Andrew Abbott has not shown the early command to trust, a 4.3 BB/9 that invites first inning traffic. Not a first inning to trust.

**Athletics at Houston Astros.** Jack Perkins's 6.96 ERA tells the story, vulnerable early and often. We are passing here.

## Before You Lock

Confirm the starting pitchers on the [NRFI dashboard](/mlb/nrfi). 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.
