This is Tony T from tonyspicks.com, and baseball is back. The All-Star break is over, the rotations are lined up, and we get a full 15-game Friday slate to sink our teeth into. My first-inning model is built on pitch-level play-by-play from every game since June 1 — a 559-game window in which the league has stayed off the board in the opening frame 47.8% of the time. That 47.8% league NRFI rate is your baseline: any team or arm running well north of it is where the value lives, and tonight we have several of them lined up in the same spots.
For the newcomers: NRFI means “No Run First Inning” — you win if neither team scores in the top or bottom of the first. YRFI (“Yes Run First Inning”) is the opposite side. I don’t guess at these. Every number below comes straight from today’s NRFI stat pack and slate card, and I’ll tell you exactly where the edges are and where the traps are hiding. Let’s get to work.
Best NRFI Bet: Rays vs. Red Sox, First 5 NRFI (Game 1, 1:35 PM ET, Fenway Park)
The early Fenway matinee is the cleanest two-sided NRFI on the board, and it starts with the arm on the mound for Boston.
Play: NRFI — Rays @ Red Sox (Game 1, 1:35 PM ET) Grade: A- (Two Elite First-Inning Arms) Key Edges:
- Jake Bennett (BOS): 0.0 runs allowed per first inning over 6 starts, 0.0% YRFI-against, 72.2% first-pitch strike rate (8 K, 0 BB in the frame)
- G. Jax (TB): 0.38 runs per first inning over 8 starts, 25.0% YRFI-against, 73.5% first-pitch strike rate
- Rays team NRFI 52.6%, allow a first-inning run just 26.3% of the time
- Red Sox allow a first-inning run 33.3%; Boston team NRFI 41.7%
Read: Bennett has been the story of the Boston rotation — six starts in the window, and the opposition has not put a single run on the board against him in the first inning. That is a perfect 0.0% YRFI-against with a 72.2% first-pitch strike rate, the profile of a starter who lives in the zone and dictates counts from pitch one. On the other side, Jax’s 0.38 runs per first over eight starts and matching 73.5% first-pitch strike rate mean both dugouts are handing the ball to strike-throwers who bury hitters early. When two arms this efficient meet, the opening frame tends to be quiet. This is our top play on the Friday card.
Note the split doubleheader here: the nightcap at 7:10 PM lists both starters as TBD, so the pitcher-level edge belongs strictly to the 1:35 game. Play the number you can verify.
Secondary NRFI Leans
Three more spots clear my baseline comfortably, each anchored by a starter who has been elite in the first inning since June 1.
1. Michael King, Padres (@ Royals, 8:10 PM ET). King checks in at 0.14 runs allowed per first inning over 7 starts with a 14.3% YRFI-against. San Diego owns a 57.9% team NRFI — fourth-best in the sport in this window — and allows a first-inning run only 26.3% of the time. The Royals bat in the bottom of the first, and King’s job is to keep the top of the frame scoreless when the Padres are in the field; his numbers say he does it consistently. I checked King’s status: he arrived at camp fully healthy this spring after last year’s setbacks and has been a fixture in the rotation. The one caution is that this is a split game — I love the King side of the first inning, but as you’ll see below, the other half of this matchup is where my favorite YRFI lives. If you want a pure suppression angle, target King’s half; if you want the full-game NRFI, know you’re fading a Royals lineup that scores first 44.7% of the time.
2. Sandy Alcantara, Marlins (@ Brewers, 7:40 PM ET). Alcantara sits at 0.25 runs per first inning over 8 starts, a 12.5% YRFI-against, and a stout 72.7% first-pitch strike rate. Miami carries a 56.8% team NRFI and allows a first-inning run just 24.3% of the time — one of the better opening-frame defenses in the league. Alcantara is confirmed active and pitching well; reporting this month has the Marlins keeping their ace rather than shopping him at the deadline. Milwaukee’s probable (Henderson) does not clear my four-start minimum in the window, so I’m leaning on the Alcantara side and the Marlins’ team profile rather than the full two-way number.
3. Jared Jones, Pirates (@ Guardians, 7:10 PM ET). Jones brings a 0.14 runs-per-first mark over 7 starts and a 14.3% YRFI-against, backed by 13 strikeouts in the frame. The reason this one is a lean and not a headline is the other dugout: Cleveland runs a 61.1% team NRFI — second-best in all of baseball — and allows a first-inning run just 22.2% of the time, yet the Guardians’ listed starter, G. Williams, carries a heavier 0.71 runs-per-first line. So you have a league-elite team defense and a shaky individual arm sharing the same box score. My read: back the Pirates’ side of the frame behind Jones, and treat the full-game NRFI as a smaller-unit play given the Williams question. Jones took a line drive off his elbow back on June 21 but imaging was clean and he’s remained in the rotation, so availability isn’t my concern here — the Williams matchup is.
Best YRFI Bet: Padres vs. Royals, Yes Run First Inning (8:10 PM ET, Kauffman Stadium)
Every quiet-first-inning board has one game screaming the other direction, and tonight it’s in Kansas City — specifically the top of the first, when the Padres come to bat against Seth Lugo.

Play: YRFI — Padres @ Royals (8:10 PM ET) Grade: B+ (Weak First-Inning Arm, Aggressive Opponent) Key Edges:
- Seth Lugo (KC): 1.29 runs allowed per first inning over 7 starts — the highest mark among matched starters on the slate
- Lugo’s YRFI-against: 71.4% (a run scored against him in the first in 5 of 7 starts)
- Royals allow a first-inning run 36.8% of the time; Kansas City team NRFI just 39.5%
- Royals themselves score first 44.7% of the time — the most aggressive first-inning bat on tonight’s matched slate
Read: This is the mirror image of the King suppression angle. Lugo has been lit up early all window — 1.29 runs per first inning and a 71.4% YRFI-against, meaning the opposition has plated a first-inning run in five of his last seven turns. The Padres don’t need to do much off a starter this vulnerable in the opening frame. Add that Kansas City’s own lineup scores first at a 44.7% clip, and you have both halves of the inning pulling toward a run. Lugo is confirmed active and starting; this is a workload-and-command read, not an availability one.
YRFI Leans
1. Reds @ Rockies, Coors Field (8:40 PM ET). Both starters are listed TBD, so there’s no pitcher-level edge to hang a card on — but the team profile and the venue do the talking. Colorado owns the league’s worst team NRFI at 34.2% and allows a first-inning run 42.1% of the time, the highest allow-rate in the pack, while also scoring first 39.5% of the time. At altitude, with the Rockies’ bottom-of-the-league first-inning containment, a YRFI lean is the natural play. Treat it as an environment-and-team lean only until the arms are confirmed.
2. White Sox @ Blue Jays (7:15 PM ET). Toronto allows a first-inning run 41.7% of the time — second-worst in this window — behind a 38.9% team NRFI. The White Sox’s A. Kay (0.43 runs per first over 7 starts) is the only matched arm here, so this is a softer lean built on the Blue Jays’ shaky first-inning defense rather than a two-way number. Small unit if you play it.
One Name I’m Setting Aside
The Mariners own the best team NRFI in baseball at 64.9% and allow a first-inning run only 21.6% of the time, and on paper their listed starter B. Miller (0.17 runs per first over 6 starts) fits any NRFI card beautifully. I’m passing. Reporting through mid-July has Bryce Miller on the injured list with right elbow inflammation and a bone spur, sidelined since early June and not expected back in the rotation until late July at the earliest. Probables can be stale, and I won’t build a play around an arm that may not take the ball. If Seattle names a healthy alternative, revisit the team number — but I’m not touching the Miller line tonight.
How I Build These
The engine behind every number above is pitch-level play-by-play since June 1 — 559 games — tracking exactly what each starter and each lineup does in the first inning: runs allowed, whether a run scored at all (YRFI-against), and first-pitch strike rate as a leading indicator of command. No estimates, no memory, no gut. If a figure isn’t in today’s pack, it isn’t in this article. For more daily picks and premium plays across the board, tonyspicks.com has you covered all season.
Lines and probable starters are subject to change before first pitch — always confirm the arm is actually taking the mound before you fire, especially in the TBD spots and the split doubleheader at Fenway. This is analysis, not a guarantee, and never a sure thing.
FAQ
What does NRFI mean? NRFI stands for “No Run First Inning.” The bet cashes if neither team scores in the top or bottom of the opening frame. YRFI is the opposite — you need at least one run in the first inning by either side.
What’s the strongest NRFI play on 7/17/2026? My top play is the Rays–Red Sox matinee (Game 1, 1:35 PM ET). Jake Bennett has allowed zero first-inning runs over six starts with a 0.0% YRFI-against, and G. Jax matches him with a 0.38 runs-per-first mark, so both dugouts are handing the ball to elite strike-throwers.
Why fade the first inning in Padres–Royals? Because Seth Lugo has been hammered early — 1.29 runs allowed per first inning and a 71.4% YRFI-against over seven starts — while Kansas City’s own lineup scores first 44.7% of the time. Both halves of the inning point toward a run, which is why it’s my best YRFI.
