These are tonight's best NRFI plays. > [NRFI Dashboard](/mlb/nrfi): live pitcher data, updated as starters confirm. > **Yesterday's NRFI picks:** [MLB NRFI Bets for September 3](/blog/mlb-nrfi-picks-sep-3-2026) ## Tonight's Slate - DET at CLE (Keider Montero vs Foster Griffin), 2:10 PM - NYY at SD (Max Fried vs Walker Buehler), 9:40 PM - ATL at PHI (Chris Sale vs Cristopher Sánchez), 6:40 PM - SF at NYM (Matt Wilkinson vs Nolan McLean), 7:10 PM - CHC at MIA (Shota Imanaga vs Janson Junk), 7:10 PM - BOS at BAL (Ranger Suarez vs Shane Baz), 7:05 PM - STL at COL (Kyle Leahy vs Ryan Feltner), 8:40 PM - TB at TEX (Nick Martinez vs Kumar Rocker), 8:05 PM - WSH at LAD (Jackson Kent vs Blake Snell), 10:10 PM ## Detroit Tigers at Cleveland Guardians *Keider Montero (RHP): 86% NRFI, 3.24 ERA, 0.99 WHIP, 6.0 K/9, 2.0 BB/9, NRFI streak of 3. Foster Griffin (LHP): 81% NRFI, 3.21 ERA, 1.12 WHIP, 8.1 K/9, 2.3 BB/9, NRFI streak of 3. First pitch 2:10 PM ET at Progressive Field (660 ft).* Neither starter hands out early traffic, and in the first inning that is most of the battle. Keider Montero runs a 2.0 BB/9 and Foster Griffin a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. On the other side, Foster Griffin is no pushover either at 81% NRFI, so this does not lean on one arm alone. Keider Montero's 2.0 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. It helps that the Detroit Tigers lineup has been quiet against LHP this year at a .643 OPS, which gives Foster Griffin margin in the opening frame. The lean is NRFI, carried by the stronger arm. ## New York Yankees at San Diego Padres *Max Fried (LHP): 75% NRFI, 2.80 ERA, 1.00 WHIP, 8.3 K/9, 2.8 BB/9, NRFI streak of 3. Walker Buehler (RHP): 78% NRFI, 4.66 ERA, 1.36 WHIP, 7.6 K/9, 3.4 BB/9. First pitch 9:40 PM ET at Petco Park (15 ft).* Walker Buehler anchors this one at 78% NRFI, and the combined 64% rate keeps the game in play as a lean. On the other side, Max Fried is no pushover either at 75% NRFI, so this does not lean on one arm alone. Walker Buehler is trending up as well, a 2.67 ERA across his last five starts against a 4.66 season mark. The pressure point is the New York Yankees lineup, which has handled RHP well this year at a .747 OPS in that split, so Walker Buehler 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). ## Atlanta Braves at Philadelphia Phillies *Chris Sale (LHP): 88% NRFI, 2.06 ERA, 1.00 WHIP, 11.1 K/9, 1.8 BB/9, NRFI streak of 2. Cristopher Sánchez (LHP): 79% NRFI, 2.52 ERA, 1.19 WHIP, 10.4 K/9, 2.0 BB/9, NRFI streak of 1. First pitch 6:40 PM ET at Citizens Bank Park (20 ft).* Chris Sale can end the first inning without the ball ever leaving the infield, missing bats at a 11.1 K/9 clip, and swing and miss is the cleanest path to a scoreless opening frame. Cristopher Sánchez holds up his end too, a 79% scoreless rate that only needs to match the moment. Chris Sale's 1.8 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. NRFI is the side, with a touch of caution. ## Honorable Mentions - **San Francisco Giants at New York Mets:** Matt Wilkinson riding a run of 3 scoreless first innings. - **Chicago Cubs at Miami Marlins:** Janson Junk riding a run of 11 scoreless first innings. - **Boston Red Sox at Baltimore Orioles:** Ranger Suarez riding a run of 7 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **St. Louis Cardinals 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. **Tampa Bay Rays at Texas Rangers.** Kumar Rocker is the weak link at 46% NRFI, and the combined 40% rate sits near the bottom of the slate. We are passing here. **Washington Nationals at Los Angeles Dodgers.** Jackson Kent has not shown the early command to trust, a 7.1 BB/9 that invites first inning traffic. 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.
