Merrill Kelly sits at 100% NRFI; Sean Burke (67%) just needs to be average for the bet to cash. Worth noting: Sean Burke's last-five ERA (5.74) is well above his season number (4.43). The trend has cooled. ## Honorable Mentions - **MIL @ DET** — Keider Montero riding a 3-game NRFI streak. - **BAL @ KC** — Shane Baz sitting at 75% NRFI. - **SD @ COL** — Randy Vásquez sitting at 100% NRFI. ## Games to Avoid These matchups have the highest first-inning scoring risk on tonight's slate: **MIN @ NYM** — Nolan McLean has allowed a first-inning run in 4 straight starts. The trend matters more than the season 0% rate, and tonight is not the spot to fade it. **HOU @ CLE** — Ryan Weiss's 6.75 ERA tells the story — he is vulnerable early and often, and the matchup math doesn't pencil out. **PHI @ CHC** — Jesús Luzardo has allowed a first-inning run in 3 straight starts. The trend matters more than the season 25% rate, and tonight is not the spot to fade it. ## 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 starting pitchers on the [NRFI dashboard](/mlb/nrfi) - a bullpen game kills NRFI value immediately. Check weather at first pitch and be careful at altitude (Coors in particular). NRFI bets land at 55-65% historically; you need ~52.4% to break even at -110.
