The Seattle Mariners and the New York Yankees will meet on Wednesday night in the second game of a three game American League series at Yankee Stadium in the Bronx, New York.

Seattle Mariners Betting Preview

The Seattle Mariners enter Wednesday’s contest with a 56–64 overall record (3rd in the American League West) and a 23–35 mark on the road. The Mariners offense has been below average to this point in the season. Through 119 games played in 2026, Seattle has compiled 463 runs scored (30th in MLB), 142 doubles (30th in MLB), 138 home runs and an abysmal .228 team batting average which ranks 30th in Major League Baseball.

The Mariners arrive at tomorrow night’s game in below average form. Seattle has lost six of the team’s last seven games played this season, including an 11-0 shutout loss to the Detroit Tigers five days ago.

Seattle will turn to right hander Bryce Miller in this game. In 13 starts made this season, Miller has compiled a 4–6 win loss record, a 3.08 ERA, a 0.95 WHIP, and 79 strikeouts, while allowing 60 hits and 15 walks in 79 innings pitched. Bryce Miller arrives at this subpar form, allowing four earned runs or more in two of his last three starts made in 2026. Miller will look to stabilize his recent poor performances on the mound in tomorrow’s matchup with the New York Yankees.

The Seattle Mariners lineup features outfielder Randy Arozarena and first baseman Josh Naylor. Randy Arozarena has tallied a .276 batting average, 15 home runs, 45 walks, 50 RBIs and an .816 OPS. Josh Naylor has compiled a .263 batting average, 10 home runs, 17 doubles, 42 RBIs and a .700 OPS.                                                                                                            

New York Yankees Betting Preview

The New York Yankees enter Wednesday evening’s matchup with a 67–52 overall record (2nd in the American League East) and a 30–26 mark at home. New York has played competitive baseball recently, winning four of the team’s last six games, including a 5–4 victory over the Atlanta Braves last week.

New York will start right hander Will Warren in tomorrow’s game. In 22 starts made in 2026, Warren has compiled an 8–6 record, a 4.18 ERA, a 1.37 WHIP, and 114 strikeouts, while allowing 119 hits and 37 walks in 114.0 innings pitched.

The New York Yankees lineup features second baseman Jazz Chisholm Jr. and first baseman Ben Rice. Chisolm Jr. enters this contest with 17 home runs, 14 doubles, 44 walks, 47 RBIs, 31 stolen bases and a .692 OPS. Ben Rice has compiled 75 RBIs (9th in MLB), 32 home runs (6th in MLB) and an .890 OPS                                                           

Why the Seattle Mariners will win.

• Offensive upside. Randy Arozarena and Josh Naylor continue to anchor the Seattle Mariners lineup.

• Starting pitching. In 13 starts made this season, Bryce Miller has compiled a 4–6 win loss record, a 3.08 ERA, a 0.95 WHIP, and 79 strikeouts in 79 innings pitched.

• Enhanced motivation. The Mariners have lost six of the team’s last seven games.

Why the New York Yankees will win.

• Home field edge. New York has played quality baseball (30–26) at Yankee Stadium this season.

• Offensive balance. Ben Rice and Jazz Chisholm Jr. provide a strong core to the Yankees lineup.

• Current form. The New York Yankees have won four of the team’s last six games.

Seattle Mariners vs. New York Yankees Prediction

In my view, the way to go in this matchup is the total rather than a side. Why? Seattle starting pitcher Bryce Miller arrives at this subpar form, allowing four earned runs or more in two of his last three starts made in 2026. Similarly, New York hurler Will Warren has had issues on the mound recently, allowing six earned runs to the Philadelphia Phillies two starts ago. I should also note that the Yankees have assembled one of the better offenses in Major League Baseball this season. With that said, I expect a high scoring affair in this contest. I am backing over 7.5 runs in this game.
