Chase Burns (RHP): 86% NRFI, 2.80 ERA, 1.15 WHIP, 10.8 K/9, 3.2 BB/9, NRFI streak of 2. First pitch 6:40 PM ET at Great American Ball Park (490 ft).* Chase Burns can end the first inning without the ball ever leaving the infield, missing bats at a 10.8 K/9 clip, and swing and miss is the cleanest path to a scoreless opening frame. On the other side, Clay Holmes is no pushover either at 81% NRFI, so this does not lean on one arm alone. The pressure point is the Chicago Cubs lineup, which has handled RHP well this year at a .765 OPS in that split, so Chase Burns cannot afford a sloppy first. NRFI projects clean here. ## Boston Red Sox at Tampa Bay Rays *Ranger Suarez (LHP): 81% NRFI, 3.33 ERA, 1.19 WHIP, 8.5 K/9, 2.6 BB/9, NRFI streak of 9. Ian Seymour (LHP): 79% NRFI, 4.27 ERA, 1.14 WHIP, 11.1 K/9, 2.5 BB/9. First pitch 7:10 PM ET at Tropicana Field, indoor.* Ranger Suarez anchors this one at 81% NRFI, and the combined 64% rate keeps the game in play as a lean. On the other side, Ian Seymour is no pushover either at 79% NRFI, so this does not lean on one arm alone. Ranger Suarez arrives on a run of 9 straight scoreless first innings. The pressure point is the Boston Red Sox lineup, which has handled LHP well this year at a .746 OPS in that split, so Ian Seymour cannot afford a sloppy first. NRFI is the side, with a touch of caution. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## Kansas City Royals at Pittsburgh Pirates *Randy Dobnak (RHP): 91% NRFI, 2.73 ERA, 1.27 WHIP, 6.1 K/9, 3.0 BB/9, NRFI streak of 6. Paul Skenes (RHP): 73% NRFI, 3.78 ERA, 1.13 WHIP, 10.3 K/9, 2.6 BB/9. First pitch 6:40 PM ET at PNC Park (730 ft).* Randy Dobnak is the reason to look here, a 91% scoreless rate in the first that carries most of the weight for this lean. Paul Skenes is the softer side at 73% NRFI, but he only has to be ordinary in the first for this to cash. Randy Dobnak arrives on a run of 6 straight scoreless first innings. The pressure point is the Pittsburgh Pirates lineup, which has handled RHP well this year at a .766 OPS in that split, so Randy Dobnak cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. ## Honorable Mentions - **San Francisco Giants at Los Angeles Dodgers:** Tyler Glasnow riding a run of 3 scoreless first innings. - **Miami Marlins at San Diego Padres:** Nick Pivetta riding a run of 5 scoreless first innings. - **Washington Nationals at St. Louis Cardinals:** a combined 57% NRFI rate. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Seattle Mariners 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. **Minnesota Twins at Los Angeles Angels.** Connor Prielipp's 5.24 ERA tells the story, vulnerable early and often. We are passing here. **Atlanta Braves at Houston Astros.** Tyler Mahle is the weak link at 60% NRFI, and the combined 42% rate sits near the bottom of the slate. Leave this one alone. ## 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.
