Baltimore Orioles vs Seattle Mariners – MLB Preview – Aug 14, 2025

The Baltimore Orioles and Seattle Mariners meet Thursday afternoon at Oriole Park at Camden Yards for the final game of a three-game series. First pitch is set for 1:05 PM ET. Baltimore won 4-3 on Wednesday for its first walk-off win of the season after Jackson Holliday’s RBI double in the ninth inning.
The Mariners have taken five of the past seven matchups between these teams, but Baltimore has won the last two series played in Camden Yards. Seattle enters at 67-54 while Baltimore is 54-66. The Orioles will try to secure their first series win over Seattle since 2022.
Orioles Preview – Looking for Timely Hits
Baltimore has struggled to score in this series, producing only five runs in the first two games. Their offense ranks near the bottom in batting average at .265 against a 4.81 team ERA. Tomoyuki Sugano starts Thursday with a 9-5 record and 4.24 ERA, having allowed no home runs in his past two outings.
Sugano pitched well in his previous meeting with Seattle this year, allowing just one run over seven innings on June 3. The bullpen has been a concern, with a 4.75 ERA from relievers in the past week. Yennier Cano and Keegan Akin combined to blow a late lead on Wednesday before Holliday’s walk-off hit.
Injuries remain an issue, with Colton Cowser still out due to concussion protocol and several pitchers on the IL. The Orioles have covered the run line in 18 of their last 29 home games despite their overall losing record.
Mariners Preview – Power Quiet in Baltimore
Seattle’s bats have been uncharacteristically quiet, scoring just four runs without a home run in the first two games of the series. Catcher Cal Raleigh leads MLB with 45 homers but is hitless in the series. The team’s offense averages 4.54 runs per game, supported by a pitching staff with a 3.78 ERA.
Rookie Logan Evans will get the start for Seattle. He’s 6-4 with a 4.36 ERA but has posted a 5.85 ERA over his past four starts despite winning three of them. This will be his first career start against Baltimore.
Seattle’s bullpen remains one of the better units in the league with a 3.18 ERA, anchored by Andres Munoz and Matt Brash. The Mariners have hit the under in eight of their last nine road games, showing a recent trend toward low-scoring results.
Betting Prediction
The Orioles are slight underdogs at home with Sugano on the mound. His past success against Seattle and the Mariners’ quiet bats this week suggest another low-scoring game is possible. Baltimore’s bullpen issues are a risk, but Seattle’s road offense has been weak lately.
With both starters capable of keeping the ball in the park and recent trends favoring the under, the safest play may be on the total. Seattle’s deeper lineup still makes them the more likely winner, but a close score is expected.
Pick: Mariners -125, Under 8.5
