What in the world happened to George Kirby? We're fading him as part of our Mariners vs. Angels prediction today.
The Los Angeles Angels host the Seattle Mariners as 45% underdogs at Polymarket, looking for the series sweep at Angel Stadium (9:38 p.m. ET). Can Yusei Kikuchi get the job done?
Let’s dive into my MLB picks for Wednesday, Sept. 16.
Who will win Mariners vs Angels today: Angels moneyline
For help understanding probabilities, see our odds calculator.
The Los Angeles Angels have buried a down-and-out Seattle Mariners team over the last couple of games, and they won't be stopping tonight, especially with George Kirby on the mound.
To say Kirby has been having a down season would be an understatement; he owns the highest xERA (4.13), xBA (.263), and xwOBA (.313) of his career, with the Angels owning a .475 xSLG across 86 plate appearances against him. What does that add up to? An upset: Los Angeles is a live 'dog today.
I'd play this up to 50%.
COVERS INTEL: Just how bad is this Mariners offense? They now lead MLB with 34 games of one-or-no-run scored this season.
Mariners vs Angels Over/Under pick: Over 7.5
The Over is hitting at a 100% clip over Kirby's last five road starts, and it likely won't change today. The right-hander has given up 12 earned runs across his last three outings (17 2/3 innings pitched), and while I believe in Yusei Kikuchi, the Mariners will do just enough offensively to get us over the line.
The Angels' lefty owns a 44.6% hard-hit rate, the highest of his career. Even this lackluster Mariners offense should be able to get to him. Let's see some runs tonight.
I'd play this to 58%.
Mariners vs Angels home run prediction: Mike Trout
Mike Trout already has a homer to his name against Kirby, and with the righty's massive struggles this season, he's in a good spot to go yard one more time. Trout's having a strong September, as well, owning a .795 OPS this month.
Expect the future Hall of Famer to sit on a mistake fastball from Kirby, a pitch he's hit 14 of his 21 homers against this season.
