Nolan McLean provided the struggling Mets a much-needed lift, tossing 5 1/3 scoreless innings in his major league debut as New York beat the Seattle Mariners 3-1.

There are many culprits. A starry, highly paid lineup main four of Francisco Lindor, Juan Soto, Pete Alonso and Brandon Nimmo has lacked enough clutch impact. A refortified bullpen has been central to blowing leads in each of the seven games going into Saturday.

Facing highly touted Mets rookie pitcher Nolan McLean, the Mariners continued a frustrating stretch of missing offense on the East Coast in a 3-1 loss.
