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 July 31](/blog/mlb-nrfi-picks-jul-31-2026) ## Tonight's Slate - AZ at CLE (Kohl Drake vs Parker Messick), 7:15 PM - SF at SD (Tyler Mahle vs Walker Buehler), 8:40 PM - CWS at TB (Jordan Hicks vs Drew Rasmussen), 4:10 PM - BOS at LAD (Payton Tolle vs Yoshinobu Yamamoto), 9:10 PM - STL at TOR (Quinn Mathews vs Kevin Gausman), 3:07 PM - PHI at BAL (Cristopher Sánchez vs Shane Baz), 7:05 PM - WSH at ATL (Miles Mikolas vs Reynaldo López), 7:15 PM - KC at COL (Luinder Avila vs Ryan Feltner), 8:10 PM - TEX at HOU (Jacob deGrom vs Ronel Blanco), 7:10 PM ## Arizona Diamondbacks at Cleveland Guardians *Kohl Drake (LHP): 0% NRFI, 5.00 ERA, 1.44 WHIP, 6.0 K/9, 4.0 BB/9. Parker Messick (LHP): 52% NRFI, 2.59 ERA, 1.04 WHIP, 8.8 K/9, 2.6 BB/9, NRFI streak of 1. First pitch 7:15 PM ET at Progressive Field (660 ft).* Parker Messick anchors this one at 52% NRFI, and the combined 72% rate keeps the game in play as a lean. Kohl Drake is the softer side at 0% NRFI, but he only has to be ordinary in the first for this to cash. A 1.04 WHIP tells the same story, very little early traffic for the lineup to work with. The pressure point is the Arizona Diamondbacks lineup, which has handled LHP well this year at a .804 OPS in that split, so Parker Messick cannot afford a sloppy first. The loose thread is Kohl Drake's 4.0 BB/9; an early walk is how this inning gets away. Both arms protect the opening frame, so NRFI is the call. ## San Francisco Giants at San Diego Padres *Tyler Mahle (RHP): 53% NRFI, 4.96 ERA, 1.40 WHIP, 8.1 K/9, 3.5 BB/9, NRFI streak of 3. Walker Buehler (RHP): 67% NRFI, 5.13 ERA, 1.41 WHIP, 8.2 K/9, 3.8 BB/9, NRFI streak of 1. First pitch 8:40 PM ET at Petco Park (15 ft).* Walker Buehler anchors this one at 67% NRFI, and the combined 64% rate keeps the game in play as a lean. Tyler Mahle is the softer side at 53% NRFI, but he only has to be ordinary in the first for this to cash. The pressure point is the San Francisco Giants lineup, which has handled RHP well this year at a .747 OPS in that split, so Walker Buehler cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## Chicago White Sox at Tampa Bay Rays *Jordan Hicks (RHP): 33% NRFI, 3.19 ERA, 1.48 WHIP, 10.5 K/9, 6.4 BB/9. Drew Rasmussen (RHP): 40% NRFI, 3.07 ERA, 0.93 WHIP, 9.1 K/9, 1.5 BB/9, NRFI streak of 1. First pitch 4:10 PM ET at Tropicana Field, indoor.* Drew Rasmussen anchors this one at 40% NRFI, and the combined 53% rate keeps the game in play as a lean. Jordan Hicks is the softer side at 33% NRFI, but he only has to be ordinary in the first for this to cash. Drew Rasmussen's 1.5 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Chicago White Sox lineup, which has handled RHP well this year at a .763 OPS in that split, so Drew Rasmussen cannot afford a sloppy first. The loose thread is Jordan Hicks's 6.4 BB/9; an early walk is how this inning gets away. There is a small NRFI edge, nothing more, so size it lightly. ## Honorable Mentions - **Boston Red Sox at Los Angeles Dodgers:** Yoshinobu Yamamoto riding a run of 6 scoreless first innings. - **St. Louis Cardinals at Toronto Blue Jays:** a combined 50% NRFI rate. - **Philadelphia Phillies at Baltimore Orioles:** a combined 48% NRFI rate. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Washington Nationals at Atlanta Braves.** Reynaldo López is the weak link at 27% NRFI, and the combined 22% rate sits near the bottom of the slate. We are passing here. **Kansas City Royals 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. **Texas Rangers at Houston Astros.** Jacob deGrom has surrendered a run in the first in 4 straight starts, and that trend matters more than the 30% season rate. 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.
