Yankees vs. Mariners Gameday
The MLB regular season keeps moving as the New York Yankees travel to T-Mobile Park to face the Seattle Mariners. New York comes in undefeated at 3-0.
Seattle sits at 2-2 after picking up a win against the Guardians.
The Yankees, led by Aaron Boone, are looking to keep that early run going. They have played clean baseball through three games, with Aaron Judge and Giancarlo Stanton leading the way. The production has been steady from the middle of the lineup.
New York has momentum early, but Seattle’s pitching gives this matchup some balance.
