Here are the pitching matchups most likely to stay scoreless in the first. > [NRFI Dashboard](/mlb/nrfi) - live pitcher data, updated as starters confirm. > **Yesterday's NRFI picks:** [MLB NRFI Bets - April 30](/blog/mlb-nrfi-picks-apr-30-2026) ## Tonight's Slate - TEX @ DET (MacKenzie Gore vs Jack Flaherty) - 6:40 PM - SF @ TB (Robbie Ray vs Shane McClanahan) - 7:10 PM - KC @ SEA (Cole Ragans vs Bryan Woo) - 9:45 PM - TOR @ MIN (Patrick Corbin vs Simeon Woods Richardson) - 8:10 PM - CLE @ ATH (Joey Cantillo vs J.T. Ginn) - 9:40 PM - CIN @ PIT (Brady Singer vs Mitch Keller) - 6:45 PM - ATL @ COL (Grant Holmes vs Jose Quintana) - 8:40 PM - LAD @ STL (Emmet Sheehan vs Matthew Liberatore) - 8:15 PM - MIL @ WSH (Jacob Misiorowski vs Jake Irvin) - 6:45 PM ## Pick 1: TEX @ DET — Comerica Park (600ft) *67% combined NRFI · 6:40 PM ET* - **MacKenzie Gore** (LHP) — 67% NRFI, 4.35 ERA, 1.29 WHIP, streak +1 - **Jack Flaherty** (RHP) — 67% NRFI, 5.33 ERA, 1.74 WHIP, streak -1 Weather is doing the heavy lifting. 44°F at first pitch in Comerica Park suppresses batted-ball distance, which favors both starters even if the matchup looked even on paper. Jack Flaherty's 5.33 season ERA is a concern beyond the first — the play is specifically about the opening frame, not the full game. ## Pick 2: SF @ TB — Tropicana Field (Indoor) *53.5% combined NRFI · 7:10 PM ET* - **Robbie Ray** (LHP) — 67% NRFI, 2.70 ERA, 1.14 WHIP, streak +3 - **Shane McClanahan** (LHP) — 40% NRFI, 3.91 ERA, 1.26 WHIP, streak +1 Robbie Ray's 67% scoreless-first rate is what makes this game playable. The other half — Shane McClanahan at 40% — is the mild risk to size against, but it's the kind of mild that wins more often than not. Robbie Ray's 1.14 WHIP means very few first-inning baserunners. The roof at Tropicana Field takes weather out of the equation entirely. > **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: KC @ SEA — T-Mobile Park (Indoor) *58.5% combined NRFI · 9:45 PM ET* - **Cole Ragans** (LHP) — 50% NRFI, 5.00 ERA, 1.48 WHIP, streak +1 - **Bryan Woo** (RHP) — 67% NRFI, 3.86 ERA, 1.06 WHIP, streak -2 Bryan Woo's 67% scoreless-first rate is what makes this game playable. The other half — Cole Ragans at 50% — is the mild risk to size against, but it's the kind of mild that wins more often than not. Cole Ragans's last-five ERA (4.44) is meaningfully better than his season 5.00 — the form is trending the right way. Bryan Woo's 1.06 WHIP keeps the bases empty early. ## Honorable Mentions - **TOR @ MIN** — combined 58.5% rate. - **CLE @ ATH** — combined 46% rate. - **CIN @ PIT** — combined 50% rate. ## Games to Avoid These matchups have the highest first-inning scoring risk on tonight's slate: **ATL @ COL** — Coors at 5,200 feet does what Coors does — even the better arm here (Grant Holmes at 67%) loses NRFI margin in this air. Pass. **LAD @ STL** — Combined NRFI rate sits at 45% — bottom of the slate. Emmet Sheehan (40%) is the bigger risk, but neither arm gives confidence in a clean first. **MIL @ WSH** — Skip this one: 42% combined NRFI rate, with Jake Irvin the obvious weak link at 17%. ## 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.
