## Tampa Bay Rays at Philadelphia Phillies

*Nick Martinez (RHP): 87% NRFI, 2.94 ERA, 1.07 WHIP, 5.5 K/9, 1.3 BB/9, NRFI streak of 6. Zack Wheeler (RHP): 81% NRFI, 3.06 ERA, 1.06 WHIP, 10.8 K/9, 2.7 BB/9, NRFI streak of 4. First pitch 2:30 PM ET at Citizens Bank Park (20 ft).*

Nick Martinez is the reason to look here, a 87% scoreless rate in the first that carries most of the weight for this lean. Zack Wheeler holds up his end too, a 81% scoreless rate that only needs to match the moment. Nick Martinez's 1.3 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. The pressure point is the Tampa Bay Rays lineup, which has handled RHP well this year at a .767 OPS in that split, so Zack Wheeler cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock.

## Atlanta Braves at Miami Marlins

*JR Ritchie (RHP): 70% NRFI, 4.79 ERA, 1.46 WHIP, 8.8 K/9, 5.5 BB/9, NRFI streak of 1. Janson Junk (RHP): 83% NRFI, 4.31 ERA, 1.31 WHIP, 6.4 K/9, 2.4 BB/9, NRFI streak of 1. First pitch 3:10 PM ET at loanDepot park, indoor.*

Janson Junk anchors this one at 83% NRFI, and the combined 61% rate keeps the game in play as a lean. JR Ritchie is the softer side at 70% NRFI, but he only has to be ordinary in the first for this to cash. The pressure point is the Atlanta Braves lineup, which has handled RHP well this year at a .761 OPS in that split, so Janson Junk cannot afford a sloppy first. The loose thread is JR Ritchie's 5.5 BB/9; an early walk is how this inning gets away. The lean is NRFI, carried by the stronger arm.

## Pittsburgh Pirates at Detroit Tigers

*Jared Jones (RHP): 85% NRFI, 3.87 ERA, 1.12 WHIP, 10.9 K/9, 2.9 BB/9, NRFI streak of 7. River Ryan (RHP): 100% NRFI, 0.00 ERA, 1.00 WHIP, 9.0 K/9, 3.0 BB/9, NRFI streak of 1. First pitch 3:10 PM ET at Comerica Park (600 ft).*

This is the kind of matchup NRFI bettors circle. Jared Jones (85% NRFI) and River Ryan (100%) both clear the bar comfortably, and the 60% combined rate is the proof. A 1.00 WHIP tells the same story, very little early traffic for the lineup to work with. The pressure point is the Pittsburgh Pirates lineup, which has handled RHP well this year at a .763 OPS in that split, so River Ryan cannot afford a sloppy first. The lean is NRFI, carried by the stronger arm.

## Honorable Mentions

- **Chicago Cubs at Boston Red Sox:** a combined 59% NRFI rate.
- **Cleveland Guardians at Kansas City Royals:** Parker Messick riding a run of 3 scoreless first innings.
- **Arizona Diamondbacks at San Diego Padres:** a combined 55% NRFI rate.

## Games to Avoid

These matchups carry the highest first inning scoring risk on tonight's slate.

**New York Mets at Washington Nationals.** DJ Herz has not shown the early command to trust, a 4.5 BB/9 that invites first inning traffic. Not a first inning to trust.

**Cincinnati Reds at Toronto Blue Jays.** Max Scherzer's 6.14 ERA tells the story, vulnerable early and often. This is a spot to skip.

**Colorado Rockies at Chicago White Sox.** Kyle Freeland's 6.58 ERA tells the story, vulnerable early and often. This is a spot to skip.

## Before You Lock

Confirm the starting pitchers on the [NRFI dashboard](/mlb/nrfi). A bullpen game kills NRFI value immediately. Check the weather at first pitch and be careful at altitude, Coors in particular. NRFI bets land 55% to 65% of the time historically, and you need roughly 52.4% to break even at minus 110 odds.
