Bryan Woo (RHP): 50% NRFI, 4.23 ERA, 1.07 WHIP, 8.8 K/9, 1.7 BB/9, NRFI streak of 2. First pitch 8:08 PM ET at T-Mobile Park, indoor.* Neither starter hands out early traffic, and in the first inning that is most of the battle. Logan Webb runs a 2.3 BB/9 and Bryan Woo a 1.7 BB/9, so a walk is unlikely to spark the run this bet is fading. Bryan Woo is the softer side at 50% 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 .781 OPS in that split, so Bryan Woo cannot afford a sloppy first. Both arms protect the opening frame, so NRFI is the call. ## Baltimore Orioles at Houston Astros *Trevor Rogers (LHP): 65% NRFI, 4.48 ERA, 1.31 WHIP, 6.9 K/9, 3.1 BB/9, NRFI streak of 1. Spencer Arrighetti (RHP): 50% NRFI, 4.50 ERA, 1.33 WHIP, 8.9 K/9, 4.8 BB/9, NRFI streak of 3. First pitch 4:10 PM ET at Daikin Park, indoor.* Trevor Rogers anchors this one at 65% NRFI, and the combined 61% rate keeps the game in play as a lean. Spencer Arrighetti is the softer side at 50% NRFI, but he only has to be ordinary in the first for this to cash. Trevor Rogers is trending up as well, a 1.20 ERA across his last five starts against a 4.48 season mark. The loose thread is Spencer Arrighetti's 4.8 BB/9; an early walk is how this inning gets away. 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). ## Miami Marlins at Milwaukee Brewers *Max Meyer (RHP): 47% NRFI, 2.58 ERA, 1.11 WHIP, 9.7 K/9, 3.2 BB/9, NRFI streak of 1. Shane Drohan (LHP): 78% NRFI, 3.09 ERA, 1.20 WHIP, 8.6 K/9, 2.6 BB/9, NRFI streak of 2. First pitch 4:10 PM ET at American Family Field, indoor.* Shane Drohan is the reason to look here, a 78% scoreless rate in the first that carries most of the weight for this lean. Max Meyer is the softer side at 47% NRFI, but he only has to be ordinary in the first for this to cash. Shane Drohan is trending up as well, a 2.39 ERA across his last five starts against a 3.09 season mark. The pressure point is the Milwaukee Brewers lineup, which has handled RHP well this year at a .774 OPS in that split, so Max Meyer cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. ## Honorable Mentions - **Tampa Bay Rays at Boston Red Sox:** Patrick Sandoval sitting at 100% NRFI. - **Pittsburgh Pirates at Cleveland Guardians:** a combined 58% NRFI rate. - **New York Mets at Philadelphia Phillies:** Jesús Luzardo riding a run of 4 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Los Angeles Dodgers at New York Yankees.** Ryan Weathers has surrendered a run in the first in 4 straight starts, and that trend matters more than the 33% season rate. Leave this one alone. **Chicago White Sox at Toronto Blue Jays.** Shane Bieber has not shown the early command to trust, a 5.2 BB/9 that invites first inning traffic. We are passing here. **Texas Rangers at Atlanta Braves.** Owen Murphy is the weak link at 0% NRFI, and the combined 45% 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.
