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 September 14](/blog/mlb-nrfi-picks-sep-14-2026) ## Tonight's Slate - MIA at AZ (Janson Junk vs Michael Soroka), 9:40 PM - CWS at CLE (Davis Martin vs Foster Griffin), 6:40 PM - BOS at TEX (Patrick Sandoval vs Cody Bradford), 8:05 PM - KC at HOU (Michael Wacha vs Hunter Brown), 8:10 PM - NYY at MIN (Max Fried vs Bailey Ober), 7:40 PM - PHI at WSH (Cristopher Sánchez vs Jackson Kent), 6:45 PM - SF at STL (Blade Tidwell vs Andre Pallante), 7:45 PM - SD at COL (Walker Buehler vs Ryan Feltner), 8:40 PM - SEA at LAA (Logan Gilbert vs Ryan Johnson), 9:38 PM ## Miami Marlins at Arizona Diamondbacks *Janson Junk (RHP): 86% NRFI, 4.54 ERA, 1.32 WHIP, 6.0 K/9, 2.4 BB/9, NRFI streak of 13. Michael Soroka (RHP): 72% NRFI, 3.53 ERA, 1.16 WHIP, 8.6 K/9, 2.3 BB/9. First pitch 9:40 PM ET at Chase Field, indoor.* Neither starter hands out early traffic, and in the first inning that is most of the battle. Janson Junk runs a 2.4 BB/9 and Michael Soroka a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. Michael Soroka is the softer side at 72% NRFI, but he only has to be ordinary in the first for this to cash. Janson Junk arrives on a run of 13 straight scoreless first innings. The pressure point is the Miami Marlins lineup, which has handled RHP well this year at a .757 OPS in that split, so Michael Soroka cannot afford a sloppy first. NRFI is the side, with a touch of caution. ## Chicago White Sox at Cleveland Guardians *Davis Martin (RHP): 77% NRFI, 4.05 ERA, 1.31 WHIP, 7.7 K/9, 2.8 BB/9, NRFI streak of 2. Foster Griffin (LHP): 83% NRFI, 3.65 ERA, 1.18 WHIP, 8.1 K/9, 2.4 BB/9, NRFI streak of 5. First pitch 6:40 PM ET at Progressive Field (660 ft).* Foster Griffin anchors this one at 83% NRFI, and the combined 61% rate keeps the game in play as a lean. On the other side, Davis Martin is no pushover either at 77% NRFI, so this does not lean on one arm alone. Foster Griffin arrives on a run of 5 straight scoreless first innings. NRFI is the side, with a touch of caution. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## Boston Red Sox at Texas Rangers *Patrick Sandoval (LHP): 82% NRFI, 4.58 ERA, 1.76 WHIP, 9.3 K/9, 4.4 BB/9, NRFI streak of 3. Cody Bradford (LHP): 71% NRFI, 4.72 ERA, 1.57 WHIP, 4.5 K/9, 2.4 BB/9, NRFI streak of 2. First pitch 8:05 PM ET at Globe Life Field, indoor.* Patrick Sandoval anchors this one at 82% NRFI, and the combined 61% rate keeps the game in play as a lean. Cody Bradford is the softer side at 71% NRFI, but he only has to be ordinary in the first for this to cash. Patrick Sandoval arrives on a run of 3 straight scoreless first innings. The pressure point is the Texas Rangers lineup, which has handled LHP well this year at a .799 OPS in that split, so Patrick Sandoval cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. ## Honorable Mentions - **Kansas City Royals at Houston Astros:** Hunter Brown riding a run of 4 scoreless first innings. - **New York Yankees at Minnesota Twins:** Max Fried riding a run of 5 scoreless first innings. - **Philadelphia Phillies at Washington Nationals:** Cristopher Sánchez riding a run of 3 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **San Francisco Giants at St. Louis Cardinals.** Blade Tidwell is the weak link at 43% NRFI, and the combined 33% rate sits near the bottom of the slate. Leave this one alone. **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. Not a first inning to trust. **Seattle Mariners at Los Angeles Angels.** Logan Gilbert is the weak link at 59% NRFI, and the combined 42% rate sits near the bottom of the slate. Not a first inning to trust. ## 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.
