Miami Marlins vs Athletics
Miami Marlins at Athletics (2026-07-05). Eury Pérez vs Gage Jump at Sutter Health Park.
Pérez brings a 4.21 ERA and 1.21 WHIP through 72.2 innings, with the swing-and-miss edge clearly intact at 10.03 K/9, though his 3.96 BB/9 keeps traffic on the bases and his 1.61 HR/9 leaves him vulnerable when command slips. His recent run has been sharper than the full-season line suggests, allowing one earned run or fewer in four of his last five starts, and his ERA has trended down from 5.33 on May 17 to 4.21 after his latest outing. Jump has been more efficient overall, posting a 2.93 ERA, 1.13 WHIP, 40 innings, 9.0 K/9, and just 2.25 BB/9 across seven starts. The one caution is that his last outing was his roughest in weeks, as the Dodgers tagged him for five earned runs and 11 hits in 4.2 innings after he had allowed only four earned runs total across his previous five starts.
Offensively, these teams are closely matched on the surface. Miami owns a .732 OPS with 409 runs, while the Athletics sit at a .737 OPS with 408 runs, and the home side has shown a bit more power with 113 homers versus 87 for the Marlins. The bigger split is on the mound over the full season: Miami’s staff has a 4.06 ERA and 1.25 WHIP compared with Oakland’s 5.07 ERA and 1.46 WHIP, suggesting the Marlins have been better equipped to limit baserunners and damage beyond the starting matchup. Both lineups also draw walks at a healthy clip, with Miami at 307 and the Athletics at 327, which matters against a Pérez profile that can run deep counts.
The recent head-to-head sample from 2025 produced two Athletics wins in three games, with totals of five, 15, and seven runs, so there was no single scoring pattern across that series. A total of 9.5 reflects the tension between two capable current starters and a much shakier overall Athletics pitching staff, especially if Jump’s recent contact-heavy outing proves more than a one-game blip. Pérez’s strikeout upside points toward run suppression early, but his walk rate and home-run rate also fit a number that is not especially low.
