Royals vs. Mariners: Game 3 prediction, lineup, odds, injuries, and picks

The Royals and Mariners enter Game 3 tied at one win each, setting the stage for a critical battle at T-Mobile Park.

Both teams know how much’s on the line in this tight AL Wild Card race, and with two young pitchers looking to prove themselves, this game could easily tip the momentum in either direction.

Royals vs. Mariners Pitcher & Hitter Matchups

Starting Pitchers

Logan Gilbert has quietly been a solid anchor for the Mariners this season. With a 3.55 ERA and a sharp 0.92 WHIP, he’s the kind of pitcher who keeps hitters guessing and makes you earn every run. Tonight, he’ll look to keep the Royals’ bats quiet and give Seattle’s offense a chance to take control.

Noah Cameron has been one of the Royals’ bright spots this year. His 2.79 ERA and steady command show he’s someone who can frustrate hitters and keep his team in the game. If he can keep the Mariners’ power hitters off balance, Kansas City will have a real shot at swinging this series in their favor.

Hot Hitters

Bobby Witt Jr. is the spark plug for Kansas City. Hitting .286 with 11 homers and 45 RBIs, he’s the kind of player who brings energy every time he steps up to the plate and on the field. His blend of power, speed and defense makes him a constant threat and a player the Royals rely on to shift the momentum.

For Seattle, Cal Raleigh has been a one-man wrecking crew. Leading the team with 33 homers and 71 RBIs, Raleigh’s bat has been booming all season. When he’s locked in, he can turn any pitch into trouble for opposing pitchers. Expect him to be a focal point in the Mariners’ lineup as they try to pull ahead.
