The Seattle Mariners host the Minnesota Twins at T-Mobile Park on Friday, July 31, with first pitch scheduled for 10:10 PM ET. Bryce Miller gets the ball for Seattle against Minnesota's Zebby Matthews in what shapes up as an intriguing pitching matchup between two arms who have carved out rotation spots in 2026. With the AL West race deep into its second half, every home game at T-Mobile Park carries real weight for a Mariners club looking to protect its home turf.

Pitching Matchup: Bryce Miller vs. Zebby Matthews

Miller is the headliner here. The right-hander has developed into one of the more reliable starters in Seattle's rotation, built on a high-spin fastball and an ability to generate weak contact. He's made T-Mobile Park feel like a genuine fortress when he's locked in, and a home start gives him every advantage.

Matthews is the wild card. The young Minnesota lefty has shown enough in 2026 to hold down a spot in the Twins' rotation, but he's still an arm the Mariners will look to exploit early. Getting into the opposing bullpen quickly would be a significant victory for Seattle's lineup.

Keys to Watch

Julio Rodríguez Hitting Cleanup

J-Rod batting fourth is the lineup's centerpiece. He's the kind of middle-of-the-order presence who can change a game with one swing, and getting him good pitches to hit with Naylor and Raleigh behind him puts real pressure on Matthews to execute.

Cal Raleigh's Bat in the Six Hole

Raleigh hitting sixth means the Mariners have power threaded throughout this order. Minnesota pitchers can't pitch around the top of the lineup and exhale — Raleigh is a legitimate threat who can do damage against any pitcher who loses focus.

Cole Young Setting the Table

The leadoff job belonging to Young is a statement about how far the young second baseman has come. His ability to get on base and create early pressure against Matthews will set the tone for how Seattle's offense flows through the lineup.

Royce Lewis as the Twins' Danger Man

Minnesota's most dangerous bat in this lineup is Lewis at first base, hitting fifth. Miller will need to be sharp against him. A mistake pitch to Lewis in a big spot could flip this game in a hurry.

Prediction

Miller at home is a tough assignment for any visiting lineup, and this Twins group is leaning on some youth. Seattle's lineup has enough depth — particularly in the middle with Rodríguez, Naylor, and Raleigh — to generate runs against a pitcher in Matthews who is still finding his footing at this level. Give the edge to the Mariners. Seattle wins, 4–2.
