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 August 17](/blog/mlb-nrfi-picks-aug-17-2026) ## Tonight's Slate - TOR at TB (José Soriano vs Nick Martinez), 6:40 PM - SEA at MIL (Bryce Miller vs Kyle Harrison), 7:40 PM - WSH at TEX (Jackson Kent vs Cal Quantrill), 8:05 PM - SF at CLE (Carson Whisenhunt vs Foster Griffin), 6:40 PM - MIA at PHI (Cade Gibson vs Zack Wheeler), 6:40 PM - AZ at BOS (Merrill Kelly vs Ranger Suarez), 7:10 PM - LAD at COL (Eric Lauer vs Ryan Feltner), 8:40 PM - ATL at MIN (Tyler Mahle vs Zebby Matthews), 7:40 PM - STL at CIN (Kyle Leahy vs Andrew Abbott), 6:40 PM ## Toronto Blue Jays at Tampa Bay Rays *José Soriano (RHP): 75% NRFI, 3.16 ERA, 1.25 WHIP, 9.1 K/9, 4.2 BB/9, NRFI streak of 11. Nick Martinez (RHP): 87% NRFI, 2.74 ERA, 1.09 WHIP, 5.1 K/9, 1.3 BB/9, NRFI streak of 2. First pitch 6:40 PM ET at Tropicana Field, indoor.* Nick Martinez is the reason to look here, a 87% scoreless rate in the first that carries most of the weight for this lean. On the other side, José Soriano is no pushover either at 75% NRFI, so this does not lean on one arm alone. Nick Martinez's 1.3 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Tampa Bay Rays lineup, which has handled RHP well this year at a .781 OPS in that split, so José Soriano cannot afford a sloppy first. The loose thread is José Soriano's 4.2 BB/9; an early walk is how this inning gets away. NRFI is the side, with a touch of caution. ## Seattle Mariners at Milwaukee Brewers *Bryce Miller (RHP): 79% NRFI, 3.39 ERA, 0.99 WHIP, 8.9 K/9, 1.7 BB/9, NRFI streak of 1. Kyle Harrison (LHP): 79% NRFI, 2.99 ERA, 1.13 WHIP, 11.0 K/9, 2.3 BB/9, NRFI streak of 2. First pitch 7:40 PM ET at American Family Field, indoor.* Neither starter hands out early traffic, and in the first inning that is most of the battle. Bryce Miller runs a 1.7 BB/9 and Kyle Harrison a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. On the other side, Kyle Harrison is no pushover either at 79% NRFI, so this does not lean on one arm alone. Bryce Miller's 1.7 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 RHP well this year at a .750 OPS in that split, so Bryce Miller 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). ## Washington Nationals at Texas Rangers *Jackson Kent (LHP): 100% NRFI, 6.75 ERA, 2.00 WHIP, 13.5 K/9, 11.3 BB/9, NRFI streak of 1. Cal Quantrill (RHP): 88% NRFI, 3.44 ERA, 1.20 WHIP, 6.3 K/9, 2.8 BB/9, NRFI streak of 5. First pitch 8:05 PM ET at Globe Life Field, indoor.* This is the kind of matchup NRFI bettors circle. Jackson Kent (100% NRFI) and Cal Quantrill (88%) both clear the bar comfortably, and the 61% combined rate is the proof. NRFI is the side, with a touch of caution. ## Honorable Mentions - **San Francisco Giants at Cleveland Guardians:** a combined 59% NRFI rate. - **Miami Marlins at Philadelphia Phillies:** Zack Wheeler riding a run of 3 scoreless first innings. - **Arizona Diamondbacks at Boston Red Sox:** Merrill Kelly riding a run of 5 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Los Angeles Dodgers 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. **Atlanta Braves at Minnesota Twins.** Zebby Matthews has surrendered a run in the first in 3 straight starts, and that trend matters more than the 44% season rate. We are passing here. **St. Louis Cardinals at Cincinnati Reds.** Andrew Abbott has not shown the early command to trust, a 4.3 BB/9 that invites first inning traffic. 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.
