Seattle Mariners Can Win If…
The Mariners bounce back offensively after producing just four runs in the first two games of this series. With Cal Raleigh still leading MLB in home runs (45), they’ll look to finally go deep in Baltimore.
Rookie Logan Evans (6-4, 4.36 ERA) is riding a personal two-game win streak but needs to limit free passes—his 5.85 ERA in his last four starts is a concern. If Seattle’s lineup can combine their 4th-ranked home run total (171) with a quality start from Evans, they should be in position to take the series.
Baltimore Orioles Can Win If…
The Orioles build on the emotional lift from Jackson Holliday’s walk-off double on Wednesday. Rookie starter Tomoyuki Sugano (9-5, 4.24 ERA) has won three straight decisions and shut down Seattle earlier this year (7 IP, 1 ER on June 3).
Baltimore’s bullpen is shaky—blowing a ninth-inning lead Wednesday—so Sugano going deep into the game will be key. If Gunnar Henderson and Ryan Mountcastle can provide early offense, Baltimore could take its sixth straight series over Seattle.

The Lean
The Mariners’ superior pitching depth (3.78 team ERA, 9th in MLB) and home run power give them a slight edge, even on the road. Baltimore’s recent bullpen woes tilt this toward Seattle.
