The nine-game slate on Monday will close with an American League duel from the T-Mobile Park in Seattle, so take a look at the best Orioles vs. Mariners betting pick and odds.

Baltimore and Seattle will open a three-game series at T-Mobile Park, and the hosts are -150 moneyline favorites on Bookmaker Sportsbook. These American League rivals have met three times this season and the Mariners won two of those games.

Orioles fell short to the White Sox

The Baltimore Orioles had the longest winning streak of the season as they were on a four-game run, but that positive streak ended with a 4-3 loss to the Chicago White Sox on the road. Although they could sweep the series, the Orioles have a decent 34-40 record at the moment.

The Orioles were powerless against Chicago’s pitcher Dylan Cease, who registered even 13 strikeouts across seven innings. Cedric Mullins and Jonathan Arauz had a multi-hit game and combined for three RBIs, while Jordan Lyles took a loss and dropped to a 4-7 record. Lyles pitched for 7.0 innings and allowed four runs on six hits with four strikeouts and a walk.

Tyler Wells (5-4) will start for the 15th time this year when he faces the Mariners on Monday. The 27-year-old right-hander owns a 3.34 ERA, 1.10 WHIP, and 40/16 K/BB ratio in 64.2 innings. Wells never met the Mariners in his two-year career.

Mariners failed to extend the winning streak

The Seattle Mariners were on a five-game winning streak and on the verge of sweeping the Los Angeles Angels but fell short in a 2-1 defeat. Now, the Mariners will welcome the Orioles and Athletics in the next two series at home.

It was an electrifying duel between the Mariners and Angels in which we saw a big brawl and eight ejected players. Marco Gonzales fell to a 4-8 record after taking a loss; he allowed two runs on five hits with five strikeouts and four walks in 6.0 innings. Abraham Toro registered the lone RBI for Seattle, while Adam Frazier was the only Mariner with a multi-hit game.

George Kirby (2-2) will take the mound for the 10th time this season. The 24-year-old rookie carries a strong 3.12 ERA, 1.12 WHIP, and 47/6 K/BB ratio across 49.0 innings of work. Kirby impressed in his previous start against Baltimore as he pitched for 6.0 innings without allowing a single run.

Trends:

Baltimore:

  • 5-14 in the last 19 games when playing on the road against Seattle

Seattle:

  • 5-1 in the last six games
  • 4-1 in the last five games against an opponent in the American League

Baltimore Orioles vs. Seattle Mariners Pick  

It’s going to be a close one, but I am giving a slight advantage to the Mariners, who have been playing well of late. Kirby has been in sensational form recently; he allowed just two runs in the last two starts combined, and I think he will have another strong outing on Monday. The Orioles are batting only .225 against the right-handed pitchers, which is an opportunity for Kirby to shine. I am going with the hosts to get an edge here.

Pick: Take the Mariners to win at -150

The Total

The Mariners lost their best batter Ty France to the IL with an elbow injury and will definitely miss him for the next couple of weeks. Seattle, who is among the worst teams when it comes to average runs with below four per game, is now even weaker on offense, so I don’t expect them to erupt against Wells.

The total has gone Under in eight of Seattle’s last nine games at home, while the total went Under in each of Baltimore’s previous seven games.

Pick: Go Under 7.5 runs at -110
