Parker Messick (LHP): 92% NRFI, 2.59 ERA, 1.03 WHIP, 9.0 K/9, 2.5 BB/9, NRFI streak of 4. First pitch 6:40 PM ET at Progressive Field (660 ft).* Parker Messick is the reason to look here, a 92% scoreless rate in the first that carries most of the weight for this lean. Matt Wilkinson is the concern here with a 0% NRFI rate in his sample, the model regresses that toward the league mean, but the raw results flag early-inning vulnerability. The bet leans on the stronger arm holding the line. Parker Messick arrives on a run of 4 straight scoreless first innings. It helps that the San Francisco Giants lineup has been quiet against LHP this year at a .575 OPS, which gives Parker Messick margin in the opening frame. Matt Wilkinson's 0% NRFI rate across 0 starts is worth noting, the model applies shrinkage, but the raw results suggest caution on this side. The lean is NRFI, carried by the stronger arm. ## San Diego Padres at New York Mets *Michael King (RHP): 88% NRFI, 3.41 ERA, 1.19 WHIP, 7.9 K/9, 3.5 BB/9, NRFI streak of 4. Robert Stock (RHP): 67% NRFI, 6.57 ERA, 1.86 WHIP, 9.7 K/9, 6.0 BB/9, NRFI streak of 1. First pitch 1:10 PM ET at Citi Field (20 ft).* Michael King is the reason to look here, a 88% scoreless rate in the first that carries most of the weight for this lean. Robert Stock is the softer side at 67% NRFI, but he only has to be ordinary in the first for this to cash. Michael King arrives on a run of 4 straight scoreless first innings. The loose thread is Robert Stock's 6.0 BB/9; an early walk is how this inning gets away. NRFI is the side, with a touch of caution. > **Want the full board?** See all of today's plays on [Top Plays](/top-plays), or go deeper on the [NRFI dashboard](/mlb/nrfi). ## Chicago White Sox at Chicago Cubs *Sean Newcomb (LHP): 100% NRFI, 2.51 ERA, 1.10 WHIP, 8.5 K/9, 3.3 BB/9, NRFI streak of 2. Clay Holmes (RHP): 73% NRFI, 2.56 ERA, 1.07 WHIP, 7.0 K/9, 3.0 BB/9, NRFI streak of 1. First pitch 2:20 PM ET at Wrigley Field (600 ft).* Sean Newcomb is the reason to look here, a 100% scoreless rate in the first that carries most of the weight for this lean. Clay Holmes is the softer side at 73% NRFI, but he only has to be ordinary in the first for this to cash. Sean Newcomb is trending up as well, a 0.00 ERA across his last five starts against a 2.51 season mark. The pressure point is the Chicago Cubs lineup, which has handled LHP well this year at a .812 OPS in that split, so Sean Newcomb cannot afford a sloppy first. We will take NRFI here, a lean rather than a lock. ## Honorable Mentions - **Los Angeles Angels at Houston Astros:** Walbert Ureña riding a run of 9 scoreless first innings. - **Arizona Diamondbacks at Boston Red Sox:** Brandon Pfaadt riding a run of 4 scoreless first innings. - **Miami Marlins at Philadelphia Phillies:** Sandy Alcantara riding a run of 10 scoreless first innings. ## Games to Avoid These matchups carry the highest first inning scoring risk on tonight's slate. **Washington Nationals at Texas Rangers.** Kumar Rocker is the weak link at 43% NRFI, and the combined 33% rate sits near the bottom of the slate. This is a spot to skip. **Los Angeles Dodgers at Colorado Rockies.** Coors does what Coors does. At 5,200 feet the ball carries, and even the better arm here gives back margin in the first. This is a spot to skip. **Atlanta Braves at Minnesota Twins.** Taj Bradley has surrendered a run in the first in 3 straight starts, and that trend matters more than the 54% season rate. This is a spot to skip. ## 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 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.
