The Mets ride a three-game winning streak into Miami on Friday night, while the Marlins limp in off back-to-back losses. Robert Stock gets the ball for New York carrying a 5.81ERA and 1.75WHIP across his season ledger. He strikes out 8.54 per nine but has allowed traffic on the bases all year. The control issues are real. Janson Junk counters for Miami with a 4.00ERA, 1.28WHIP, and 6.17 strikeouts per nine. The gap in strikeout ability is measurable, but Junk has posted cleaner ratios overall. The projection calls for 5.7 runs total, split almost evenly at 2.8 for the Mets and 2.9 for the Marlins. loanDepot park carries a 0.94 run factor, so slight suppression is in play. Weather is neutral: 72 degrees, no wind. The barrel-rate leaders on both sides are Francisco Lindor at 12.3 percent, Juan Soto at 12.5 percent, and Bo Bichette at 8.8 percent. The real story sits in the first inning. Stock has kept the sheet clean through six first-inning appearances this season, a perfect 100 percent NRFI rate. Junk has done the same in 18 of 23 chances, good for 78 percent. The NRFI model pegs this one at 59 percent probability with a 5.7 percent edge on the no-run side. That is a meaningful gap. Recent park trends at loanDepot show 60 percent NRFI success over the last ten games, though scoring has run hot at an average of 7.3 runs per contest. The Mets bullpen is fully rested at 100 out of 100, while Miami sits at 84 with Dax Fulton unavailable. The strikeout model leans Stock under his 4.5 line at a projection of 3.5, confidence medium at five out of ten. Junk projects 2.6 against a 3.5 line, neutral lean with four out of ten confidence.

Run Projections & Total

That's 2.8 runs below the posted total of 8.5, suggesting a lean toward the Under.
The run projection is essentially a coin flip between these two teams.
The Bottom Line
The NRFI is the cleanest angle in this matchup. Stock has gone six-for-six in keeping first innings scoreless, and Junk has done it in 18 of 23. The model assigns a 59 percent probability and a 5.7 percent edge, backed by recent park trends showing 60 percent NRFI success over the last ten games at loanDepot. The strikeout market on Stock offers value too, with a projection of 3.5 against a posted line of 4.5. Confidence is medium at five out of ten, not a slam dunk but worth attention given his control issues and the modest 8.54 per nine rate. The total and side lack separation from the model. Focus on the first inning and the Stock strikeout under if you're hunting value.
