Seattle Mariners at Miami Marlins (2026-07-09). Bryce Miller vs Janson Junk at loanDepot park.
Miller brings ace-level run prevention into this start, posting a 1.71 ERA, 0.66 WHIP, and 10.59 K/9 across 52.2 innings, with elite control at 0.85 BB/9. His recent work has been just as sharp: over his last seven starts he has allowed only 8 earned runs in 41.2 innings, and he has issued only 3 walks while striking out 52. The trend marker is listed up, but that mostly reflects how little room there is above his current baseline; he has still logged scoreless outings in three of his last six and owns a 60 percent quality-start rate with no blowups. Junk’s profile is much less stable, with a 4.80 ERA, 1.30 WHIP, and 6.45 K/9 over 60 innings, though his 1.95 BB/9 shows he does limit free passes. The concern is recent damage contact: 20 earned runs allowed over his last four starts, no quality starts on the season, and a 40 percent blowup rate.
Offensively, Miami has been the more productive club overall, carrying a .742 OPS and 426 runs versus Seattle’s .690 OPS and 377 runs. The Marlins also enter hotter, winning seven of their last ten and five straight, while Seattle is 5-5 over its last ten and has dropped the first two games of this series, including a 2-0 loss on Wednesday. On the mound beyond the starters, Seattle has the better full-season staff numbers with a 3.54 team ERA and 1.16 WHIP compared with Miami’s 4.04 ERA and 1.24 WHIP, which matters if this game turns into a bullpen bridge after the middle innings.
The recent head-to-head sample from 2025 showed two very different scoring environments, with Seattle winning 14-0 and 7-6 before Miami answered with an 8-4 win, so the matchup history does not point cleanly in one direction on totals. An 8.0 total line sits in an interesting middle ground: Miller’s form and Seattle’s stronger overall pitching staff lean toward run suppression, but Miami’s better offense and Junk’s volatility keep the over in play if Seattle’s bats capitalize on traffic or home-run mistakes.
