Baltimore Orioles at Toronto Blue Jays
Kyle Bradish (RHP): 93% NRFI, 3.91 ERA, 1.42 WHIP, 8.3 K/9, 4.0 BB/9, NRFI streak of 14. Spencer Miles (RHP): 100% NRFI, 2.77 ERA, 1.05 WHIP, 8.4 K/9, 2.2 BB/9, NRFI streak of 6. First pitch 3:07 PM ET at Rogers Centre, indoor.
This is the kind of matchup NRFI bettors circle. Kyle Bradish (93% NRFI) and Spencer Miles (100%) both clear the bar comfortably, and the 84% combined rate is the proof. Spencer Miles's 2.2 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The loose thread is Kyle Bradish's 4.0 BB/9; an early walk is how this inning gets away. This is a clean first inning waiting to happen.
Los Angeles Angels at Washington Nationals
Walbert Ureña (RHP): 92% NRFI, 2.74 ERA, 1.21 WHIP, 8.5 K/9, 4.5 BB/9, NRFI streak of 13. Andrew Alvarez (LHP): 100% NRFI, 3.60 ERA, 1.32 WHIP, 8.6 K/9, 4.1 BB/9, NRFI streak of 14. First pitch 4:05 PM ET at Nationals Park (25 ft).
This is the kind of matchup NRFI bettors circle. Walbert Ureña (92% NRFI) and Andrew Alvarez (100%) both clear the bar comfortably, and the 82% combined rate is the proof. Andrew Alvarez arrives on a run of 14 straight scoreless first innings. It helps that the Los Angeles Angels lineup has been quiet against LHP this year at a .646 OPS, which gives Andrew Alvarez margin in the opening frame. The loose thread is Walbert Ureña's 4.5 BB/9; an early walk is how this inning gets away. Both arms protect the opening frame, so NRFI is the call.

San Diego Padres at San Francisco Giants
Michael King (RHP): 90% NRFI, 3.00 ERA, 1.17 WHIP, 7.7 K/9, 3.5 BB/9, NRFI streak of 8. Cesar Perdomo (LHP): 100% NRFI, 0.90 ERA, 0.80 WHIP, 7.2 K/9, 1.8 BB/9, NRFI streak of 1. First pitch 4:05 PM ET at Oracle Park (5 ft).
This is the kind of matchup NRFI bettors circle. Michael King (90% NRFI) and Cesar Perdomo (100%) both clear the bar comfortably, and the 71% combined rate is the proof. Cesar Perdomo is trending up as well, a 0.00 ERA across his last five starts against a 0.90 season mark. NRFI projects clean here.

- Kansas City Royals at Boston Red Sox: Ranger Suarez riding a run of 8 scoreless first innings.
- Chicago White Sox at St. Louis Cardinals: Sean Newcomb riding a run of 4 scoreless first innings.
- Pittsburgh Pirates at Chicago Cubs: Paul Skenes riding a run of 6 scoreless first innings.
Games to Avoid
These matchups carry the highest first inning scoring risk on tonight's slate.
New York Mets at New York Yankees. Zac Thornton is the weak link at 42% NRFI, and the combined 37% rate sits near the bottom of the slate. Not a first inning to trust.
Cleveland Guardians at Minnesota Twins. Daniel Espino is the weak link at 0% NRFI, and the combined 40% rate sits near the bottom of the slate. We are passing here.
Texas Rangers at Arizona Diamondbacks. Kumar Rocker is the weak link at 46% NRFI, and the combined 43% rate sits near the bottom of the slate. We are passing here.

Before You Lock
Confirm the starting pitchers on the NRFI dashboard. 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.
