Detroit Tigers at Toronto Blue Jays
Drew Anderson (RHP): 88% NRFI, 3.80 ERA, 1.31 WHIP, 9.7 K/9, 3.7 BB/9. Braydon Fisher (RHP): 100% NRFI, 3.22 ERA, 1.22 WHIP, 9.0 K/9, 4.7 BB/9, NRFI streak of 9. First pitch 7:07 PM ET at Rogers Centre, indoor.
Both arms walk into Rogers Centre capable of a clean opening frame, Drew Anderson at 88% NRFI on the year and Braydon Fisher at 100%, a combined 77% that ranks among the best on the board. Braydon Fisher is trending up as well, a 1.73 ERA across his last five starts against a 3.22 season mark. The pressure point is the Detroit Tigers lineup, which has handled RHP well this year at a .755 OPS in that split, so Braydon Fisher cannot afford a sloppy first. This is a clean first inning waiting to happen.
Miami Marlins at Arizona Diamondbacks
Janson Junk (RHP): 86% NRFI, 4.54 ERA, 1.32 WHIP, 6.0 K/9, 2.4 BB/9, NRFI streak of 13. Michael Soroka (RHP): 72% NRFI, 3.53 ERA, 1.16 WHIP, 8.6 K/9, 2.3 BB/9. First pitch 9:40 PM ET at Chase Field, indoor.
Neither starter hands out early traffic, and in the first inning that is most of the battle. Janson Junk runs a 2.4 BB/9 and Michael Soroka a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. Michael Soroka is the softer side at 72% NRFI, but he only has to be ordinary in the first for this to cash. Janson Junk arrives on a run of 13 straight scoreless first innings. The pressure point is the Miami Marlins lineup, which has handled RHP well this year at a .754 OPS in that split, so Michael Soroka cannot afford a sloppy first. NRFI is the side, with a touch of caution.

Kansas City Royals at Houston Astros
Michael Wacha (RHP): 79% NRFI, 3.25 ERA, 1.11 WHIP, 7.3 K/9, 2.4 BB/9, NRFI streak of 1. Hunter Brown (RHP): 82% NRFI, 3.52 ERA, 1.30 WHIP, 9.8 K/9, 4.5 BB/9, NRFI streak of 4. First pitch 8:10 PM ET at Daikin Park, indoor.
Hunter Brown anchors this one at 82% NRFI, and the combined 60% rate keeps the game in play as a lean. Michael Wacha holds up his end too, a 79% scoreless rate that only needs to match the moment. Hunter Brown arrives on a run of 4 straight scoreless first innings. The pressure point is the Houston Astros lineup, which has handled RHP well this year at a .758 OPS in that split, so Michael Wacha cannot afford a sloppy first. The lean is NRFI, carried by the stronger arm.
Honorable Mentions
- Milwaukee Brewers at Pittsburgh Pirates: Lake Bachar riding a run of 3 scoreless first innings.
- New York Yankees at Minnesota Twins: Max Fried riding a run of 5 scoreless first innings.
- Philadelphia Phillies at Washington Nationals: Cristopher Sánchez riding a run of 3 scoreless first innings.
Games to Avoid
These matchups carry the highest first inning scoring risk on tonight's slate.
San Francisco Giants at St. Louis Cardinals. Blade Tidwell is the weak link at 43% NRFI, and the combined 28% rate sits near the bottom of the slate. Leave this one alone.
Seattle Mariners at Los Angeles Angels. Logan Gilbert is the weak link at 59% NRFI, and the combined 41% rate sits near the bottom of the slate. Not a first inning to trust.
San Diego Padres 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.

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.
