What happened: The Mets have posted their Game 1 starting lineup ahead of first pitch in Washington, with Nolan McLean slated to take the ball. The card sets New York's batting order and confirms McLean as the starting pitcher for the opener.

Why it matters: Each start is another data point on McLean's place in the New York rotation, and the Game 1 assignment shapes how the Mets line up their pitching across the slate. Lineup construction and the order of the bats matter for how the offense sets the tone early.

What to watch: Watch McLean's command and early efficiency, and whether the posted batting order holds once the game begins.
