The Mariners are expected to start Luis Castillo, who is 2-5 with a 5.53 ERA, 1.45 WHIP, 55.1 innings pitched, 58 hits allowed, 56 strikeouts, 22 walks, and 7 home runs allowed. The Tigers are expected to start Jack Flaherty, who is 1-7 with a 5.31 ERA, 1.60 WHIP, 57.2 innings pitched, 60 hits allowed, 70 strikeouts, 32 walks, and 8 home runs allowed.

Seattle Looks to Steady the Road Trip

The Mariners enter this matchup at 33-31 overall and 14-15 on the road. Seattle recently lost to Detroit 7-3, lost to New York 7-1, won over New York 8-3, won over New York 3-2 in 10 innings, and won over Arizona 3-2 in 10 innings. The Mariners have three wins in their last five games.

Seattle is batting .235 with 270 runs, 500 hits, 83 home runs, a .318 on-base percentage, and a .399 slugging percentage. The Mariners have a 3.53 ERA, 1.19 WHIP, 158 walks, 553 strikeouts, and a .244 opponent batting average.

Seattle’s best edge is pitching stability. The Mariners have the better ERA, WHIP, and walk total compared with Detroit. They also have more home runs, which gives them another statistical advantage.

Detroit Carries a Four-Game Push

The Tigers enter at 26-38 overall and 15-14 at home. Detroit recently won over Seattle 7-3, won over Tampa Bay 7-2, won over Tampa Bay 8-0, won over Tampa Bay 10-9, and lost to Chicago 2-1. The Tigers have won four of their last five games.

Detroit is batting .237 with 255 runs, 503 hits, 63 home runs, a .316 on-base percentage, and a .384 slugging percentage. The Tigers pitching staff has a 4.00 ERA, 1.27 WHIP, 213 walks, 514 strikeouts, and a .237 opponent batting average.

Detroit’s key strength is recent momentum. The Tigers have won four straight games and scored at least seven runs in each of those victories. The concern is that Seattle still holds advantages in record, power, ERA, and WHIP.

Seattle Mariners vs Detroit Tigers Picks and Prediction

Seattle Mariners vs Detroit Tigers Pick

• Pick: Seattle Mariners Moneyline

Seattle is the pick because the Mariners have the better overall record, more runs scored, more home runs, better ERA, better WHIP, and fewer walks allowed. Detroit has the stronger recent form, but the broader team statistics give Seattle enough of an edge.

Seattle Mariners vs Detroit Tigers Total Pick

• Pick: Over

Take the over if the total is set at 8.5. I lean over because Detroit has scored seven, seven, eight, and ten runs over its last four wins, while both projected starters enter with ERAs above 5.00. Seattle also has more home runs than Detroit, which supports the over angle.

Final Score Prediction: Seattle Mariners 6 – Detroit Tigers 4
