Baltimore counters with Kyle Bradish, who has quietly rebuilt his season after a rough April. Seattle opened as a narrow road favorite, and our headline lean rides with the Mariners on a near coin-flip moneyline. Below, we break down both picks and the angle behind them.

Seattle Mariners vs. Baltimore Orioles Game Preview
The pitching edge belongs to Seattle, at least on the season-long numbers. Woo carries a low-3.00s ERA with a 1.00 WHIP and roughly six innings per start. He limits free passes and keeps traffic off the bases, which is exactly the profile that travels well on the road. Baltimore's probable starter Kyle Bradish sits with a 3.89 ERA and a 3-7 record, but the won-loss line undersells him. His WHIP is higher at 1.51, yet his recent game logs show a sharp turnaround from a shaky start to the year. In other words, this is not the same pitcher who struggled in April.
Both clubs sit near the middle of the standings entering the finale. Seattle arrives at 36-33 and has stayed in the Wild Card mix all season. Baltimore, at 32-37, has played better lately and remains dangerous at home. The Orioles actually out-score the Mariners on the year, ranking among the league's better run-producing lineups. Seattle's offense leans on Randy Arozarena and Julio Rodríguez, while Baltimore counters with power bats like Pete Alonso and Gunnar Henderson. In short, the run-prevention edge favors Seattle, but the home lineup has more thump.

Moneyline Pick — Seattle Mariners ML
With Seattle priced at -115, the run line offers little value. Asking Woo to win by two or more on the road is a tougher sell, so the straight moneyline is the cleaner side. The case starts with command. Woo's 1.00 WHIP and high strikeout rate let him work deep without handing out free bases. That matters against a Baltimore lineup that does its damage when it gets extra runners.
The Pick: Seattle Mariners Moneyline (-115)
The opposing view is fair, and the line reflects it. Baltimore is essentially a pick'em at home, and Bradish has been sharp lately. His recent run of strong starts means Seattle's bats may not get many free looks either. The Orioles also carry real home-park pop, and one swing from Alonso or Henderson can flip a tight game. Still, at a near coin-flip number, we side with the more efficient starter and the team holding the better record. Seattle's edge is small but real, and that is enough at this price.
Total Pick — Under 8.5
The total sits at 8.5, and the starting pitching points toward a lower-scoring night. Woo keeps the bases clear, and Bradish has limited damage during his recent stretch. When both starters work efficiently, the early innings tend to stay quiet. Seattle's offense has been streaky and ranks in the lower half of the league in scoring, which adds to the under lean. The line has not moved much off its open at 8.5, which tells us the market sees this as a pitcher-friendly matchup too.
The Pick: Under 8.5 (-105)
The counter is straightforward. Camden Yards can play to power, and Baltimore ranks among the better run-scoring teams in baseball. If either bullpen gets exposed late, the number can climb in a hurry. However, two starters who limit walks usually keep games under control through six. We will take the under and lean on the arms.
Final Thoughts and Bonus Angle
The swing factor here is the first five innings. Both teams send out their listed starters with clear plans, and the bullpens only matter if the score stays close. Watch how Bradish handles the top of Seattle's order early. If he keeps Arozarena and Rodríguez off the bases, the Orioles can stay in front of Woo and force a late-game decision.
