## Tonight's Slate

- BOS @ CLE (Sonny Gray vs Parker Messick) - 4:10 PM
- SD @ WSH (Michael King vs Foster Griffin) - 4:05 PM
- CHC @ STL (Ben Brown vs Kyle Leahy) - 7:15 PM
- MIL @ HOU (Brandon Sproat vs Peter Lambert) - 4:10 PM
- TOR @ BAL (Trey Yesavage vs Brandon Young) - 4:05 PM
- PHI @ LAD (Jesús Luzardo vs Roki Sasaki) - 10:10 PM

- ATL @ CIN (Martín Pérez vs Brady Singer) - 7:15 PM
- DET @ CWS (Framber Valdez vs Anthony Kay) - 2:10 PM

## Pick 1: BOS @ CLE — Progressive Field (660ft)

*61% combined NRFI · 4:10 PM ET*

- **Sonny Gray** (RHP) — 67% NRFI, 3.27 ERA, 1.20 WHIP, streak -1
- **Parker Messick** (LHP) — 55% NRFI, 2.24 ERA, 1.04 WHIP, streak +2

Sonny Gray is the anchor here — a 67% NRFI rate that does most of the work for this play. Parker Messick on the other side is fine at 55%, but it's the elite arm carrying the lean.

Sonny Gray's last-five ERA (2.33) is meaningfully better than his season 3.27 — the form is trending the right way. Parker Messick's 1.04 WHIP keeps the bases empty early.

## Pick 2: SD @ WSH — Nationals Park (25ft)

*64% combined NRFI · 4:05 PM ET*

- **Michael King** (RHP) — 73% NRFI, 2.76 ERA, 1.15 WHIP, streak -2
- **Foster Griffin** (LHP) — 55% NRFI, 3.63 ERA, 1.13 WHIP, streak +1

Neither starter lets traffic on base. Michael King carries a 1.15 WHIP, Foster Griffin a 1.13 — that means few first-inning baserunners, which means few first-inning runs.

Worth noting: Foster Griffin's last-five ERA (4.80) is up from his 3.63 season mark.

## Pick 3: CHC @ STL — Busch Stadium (455ft)

*60% combined NRFI · 7:15 PM ET*

- **Ben Brown** (RHP) — 50% NRFI, 2.01 ERA, 0.99 WHIP, streak +1
- **Kyle Leahy** (RHP) — 70% NRFI, 4.44 ERA, 1.58 WHIP, streak +1

Kyle Leahy's 70% scoreless-first rate is what makes this game playable. The other half — Ben Brown at 50% — is the mild risk to size against, but it's the kind of mild that wins more often than not.

Kyle Leahy's recent ERA (3.44 over his last five) is sharper than his season 4.44. Ben Brown's 0.99 WHIP means very few first-inning baserunners.

## Honorable Mentions

- **MIL @ HOU** — Peter Lambert riding a 5-game NRFI streak.
- **TOR @ BAL** — combined 55% rate.
- **PHI @ LAD** — Roki Sasaki sitting at 78% NRFI.

## Games to Avoid

These matchups have the highest first-inning scoring risk on tonight's slate:

**SF @ COL** — Coors at 5,200 feet does what Coors does — even the better arm here (Adrian Houser at 40%) loses NRFI margin in this air. Pass.

**ATL @ CIN** — Brady Singer's 6.26 ERA tells the story — he is vulnerable early and often, and the matchup math doesn't pencil out.

**DET @ CWS** — Anthony Kay has allowed a first-inning run in 4 straight starts. The trend matters more than the season 22% rate, and tonight is not the spot to fade it.

## 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.
