Ginn vs Walbert Ureña) - 9:38 PM - TOR @ NYY (Patrick Corbin vs Ryan Weathers) - 7:05 PM - NYM @ WSH (Christian Scott vs Jake Irvin) - 6:45 PM - TEX @ COL (MacKenzie Gore vs Jose Quintana) - 8:40 PM - ATL @ MIA (JR Ritchie vs Max Meyer) - 6:40 PM ## Pick 1: BOS @ KC — Kauffman Stadium (750ft) *69% combined NRFI · 7:40 PM ET* - **Sonny Gray** (RHP) — 71% NRFI, 3.18 ERA, 1.15 WHIP, streak +3 - **Seth Lugo** (RHP) — 67% NRFI, 3.76 ERA, 1.42 WHIP, streak +1 Cold weather is a quiet edge: at 63°F in Kauffman Stadium, balls don't carry and pitchers get more swing-and-miss on breaking stuff. Pair that with Sonny Gray and Seth Lugo on the mound and the lean is clear. Worth noting: Seth Lugo's last-five ERA (5.77) is up from his 3.76 season mark. Sonny Gray's 1.15 WHIP means very few first-inning baserunners. ## Pick 2: CWS @ SEA — T-Mobile Park (Indoor) *67% combined NRFI · 9:40 PM ET* - **Noah Schultz** (LHP) — 67% NRFI, 4.91 ERA, 1.36 WHIP, streak +4 - **Bryan Woo** (RHP) — 67% NRFI, 3.91 ERA, 1.00 WHIP, streak +2 When one starter is this lockdown in the first, you ride them. Noah Schultz sits at 67% NRFI; Bryan Woo (67%) just needs to be average for the bet to cash. Noah Schultz brings a 4-game NRFI streak into tonight. Worth noting: Bryan Woo's last-five ERA (5.46) is up from his 3.91 season mark. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or dive deeper on the [NRFI dashboard](/mlb/nrfi). ## Pick 3: LAD @ SD — Petco Park (15ft) *63.5% combined NRFI · 9:40 PM ET* - **Yoshinobu Yamamoto** (RHP) — 38% NRFI, 3.60 ERA, 1.00 WHIP, streak -5 - **Michael King** (RHP) — 89% NRFI, 2.63 ERA, 1.09 WHIP, streak +1 When one starter is this lockdown in the first, you ride them. Michael King sits at 89% NRFI; Yoshinobu Yamamoto (38%) just needs to be average for the bet to cash. Yoshinobu Yamamoto's 1.00 WHIP means very few first-inning baserunners. Worth flagging: Yoshinobu Yamamoto has allowed a first-inning run in 5 straight. The season profile is good but the recent trend is the opposite. ## Honorable Mentions - **BAL @ TB** — Trevor Rogers sitting at 86% NRFI. - **ATH @ LAA** — Walbert Ureña sitting at 80% NRFI. - **TOR @ NYY** — combined 53.5% rate. ## Games to Avoid These matchups have the highest first-inning scoring risk on tonight's slate: **NYM @ WSH** — Jake Irvin's 5.91 ERA tells the story — he is vulnerable early and often, and the matchup math doesn't pencil out. **TEX @ COL** — Coors at 5,200 feet does what Coors does — even the better arm here (MacKenzie Gore at 44%) loses NRFI margin in this air. Pass. **ATL @ MIA** — JR Ritchie's 25% NRFI rate is the weak link here. Combined with Max Meyer on the other side, this game has too many ways to score in the first. ## 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.
