New York Yankees vs Seattle Mariners Prediction and Same Game Parlay picks, August 13, 2026

As the Yankees welcome the Mariners on August 13, all eyes should be on Trent Grisham. He’s been sizzling lately, turning heads with his impressive consistency at the plate. In his past few games, Grisham has not only found his rhythm but has also been instrumental in driving in runs, evidenced by his recent surge in multi-hit games. Facing a Yankees pitching staff that’s seen its fair share of ups and downs, Grisham’s ability to capitalize on mistakes could be the key. The Yankees have been generous to opposing hitters, allowing a significant number of hits and runs. With a model prediction suggesting he’s likely to exceed 0.5 hits or RBIs, the odds favor Grisham to make an impact. Given his current form and the Yankees' pitching vulnerabilities, betting on Grisham to go over 0.5 feels like a strong play.

George Lombard Jr. Over 0.5 Hits+Runs+RBIs (-217)

As the Yankees gear up to face the Mariners, all eyes should be on George Lombard Jr. He’s been a key cog in New York’s offensive machine, especially at home where the pinstripes typically unleash their power. Lombard has consistently found ways to get on base, evident in his recent performances where he’s been racking up hits and driving in runs with impressive regularity. The Mariners' pitching staff, while talented, has shown vulnerability against left-handed bats—something Lombard excels at. With the Yankees' lineup featuring a host of heavy hitters, Lombard’s chances to cash in on the ‘Over 0.5’ mark look promising. Additionally, he thrives in high-pressure situations, often stepping up when the stakes are high. Given his recent form and the favorable matchup, betting on Lombard to secure at least one hit or RBI seems like a solid play in this exciting series opener.

Trent Grisham (SDP) Over 0.5 Runs Scored (-106)

As the Yankees square off against the Mariners, keep an eye on Trent Grisham for an enticing bet on over 0.5 runs. Grisham’s been heating up lately, showcasing a keen eye at the plate and consistently putting himself in scoring position. With the Yankees’ offense firing on all cylinders, they’ve averaged over five runs a game in August. Seattle’s pitching staff has struggled against left-handed hitters, and Grisham, batting from the left side, could certainly capitalize. The Mariners’ starters have been prone to giving up runs early, and as the game progresses, the Yankees’ powerful lineup will look to take advantage of any missed opportunities. Given that Grisham has been a catalyst at the top of the order, the odds favor his ability to cross home plate. With the recent trends favoring aggressive scoring, taking the over on Grisham’s runs seems like a smart play.
