These are the cleanest first inning spots on the board. > [NRFI Dashboard](/mlb/nrfi): live pitcher data, updated as starters confirm. > **Yesterday's NRFI picks:** [MLB NRFI Bets for August 20](/blog/mlb-nrfi-picks-aug-20-2026) ## Tonight's Slate - STL at PHI (Hunter Dobbins vs Jesús Luzardo), 6:40 PM - ATL at MIL (Chris Sale vs Jacob Misiorowski), 4:10 PM - SF at BOS (Logan Webb vs Sonny Gray), 7:10 PM - TB at BAL (Freddy Peralta vs Trevor Rogers), 7:15 PM - CHC at SEA (Matthew Boyd vs Emerson Hancock), 10:10 PM - PIT at LAD (Bubba Chandler vs Yoshinobu Yamamoto), 10:10 PM - CLE at COL (Joey Cantillo vs Tanner Gordon), 8:40 PM - MIN at SD (Connor Prielipp vs Randy Vásquez), 9:40 PM - CIN at AZ (Nick Lodolo vs Eduardo Rodriguez), 9:40 PM ## St. Louis Cardinals at Philadelphia Phillies *Hunter Dobbins (RHP): 86% NRFI, 3.42 ERA, 1.30 WHIP, 8.8 K/9, 3.8 BB/9, NRFI streak of 5. Jesús Luzardo (LHP): 96% NRFI, 3.23 ERA, 1.15 WHIP, 11.1 K/9, 2.8 BB/9, NRFI streak of 17. First pitch 6:40 PM ET at Citizens Bank Park (20 ft).* Both arms walk into Citizens Bank Park capable of a clean opening frame, Hunter Dobbins at 86% NRFI on the year and Jesús Luzardo at 96%, a combined 73% that ranks among the best on the board. Jesús Luzardo is trending up as well, a 2.62 ERA across his last five starts against a 3.23 season mark. The pressure point is the Philadelphia Phillies lineup, which has handled RHP well this year at a .769 OPS in that split, so Hunter Dobbins cannot afford a sloppy first. Both arms protect the opening frame, so NRFI is the call. ## Atlanta Braves at Milwaukee Brewers *Chris Sale (LHP): 86% NRFI, 2.16 ERA, 1.02 WHIP, 11.2 K/9, 2.0 BB/9. Jacob Misiorowski (RHP): 83% NRFI, 1.75 ERA, 0.75 WHIP, 13.6 K/9, 2.0 BB/9, NRFI streak of 5. First pitch 4:10 PM ET at American Family Field, indoor.* This is the kind of matchup NRFI bettors circle. Chris Sale (86% NRFI) and Jacob Misiorowski (83%) both clear the bar comfortably, and the 68% combined rate is the proof. Chris Sale's 2.0 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Milwaukee Brewers lineup, which has handled LHP well this year at a .792 OPS in that split, so Chris Sale cannot afford a sloppy first. The lean is NRFI, carried by the stronger arm. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## San Francisco Giants at Boston Red Sox *Logan Webb (RHP): 82% NRFI, 3.50 ERA, 1.06 WHIP, 7.1 K/9, 2.1 BB/9, NRFI streak of 4. Sonny Gray (RHP): 70% NRFI, 2.65 ERA, 1.15 WHIP, 8.0 K/9, 2.3 BB/9, NRFI streak of 10. First pitch 7:10 PM ET at Fenway Park (20 ft).* Neither starter hands out early traffic, and in the first inning that is most of the battle. Logan Webb runs a 2.1 BB/9 and Sonny Gray a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. Sonny Gray is the softer side at 70% NRFI, but he only has to be ordinary in the first for this to cash. Logan Webb is trending up as well, a 2.25 ERA across his last five starts against a 3.50 season mark. The pressure point is the San Francisco Giants lineup, which has handled RHP well this year at a .757 OPS in that split, so Sonny Gray cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. ## Honorable Mentions - **Tampa Bay Rays at Baltimore Orioles:** Trevor Rogers riding a run of 14 scoreless first innings. - **Chicago Cubs at Seattle Mariners:** a combined 59% NRFI rate. - **Pittsburgh Pirates at Los Angeles Dodgers:** Bubba Chandler riding a run of 3 scoreless first innings. ## 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. This is a spot to skip. **Minnesota Twins at San Diego Padres.** Connor Prielipp's 5.34 ERA tells the story, vulnerable early and often. Not a first inning to trust. **Cincinnati Reds at Arizona Diamondbacks.** Eduardo Rodriguez is the weak link at 60% NRFI, and the combined 50% rate sits near the bottom of the slate. We are passing here. ## Related Guides - [How to Use the NRFI Dashboard](/blog/how-to-use-nrfi-dashboard) - [MLB Weather Betting Guide](/blog/mlb-weather-betting-guide) - [MLB Stats Explained](/blog/mlb-stats-explained) ## 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.
