Nolan McLean’s dazzling debut powers Mets past Mariners

The Mets didn’t need Nolan McLean to be a savior Saturday, but it sure didn’t hurt that the rookie assumed such a role.

A team desperate for even decent starting pitching got the bonus package, as McLean — in his major league debut — helped the Mets, without much thunder offensively, bury their worries for an afternoon.

With that injection of energy, the Mets ended a three-game skid with a 3-1 victory over the Mariners at Citi Field.

It was only the Mets’ third victory in their last 17 games.

McLean, a top organizational pitching prospect, pitched 5 ⅓ scoreless innings in which he allowed two hits and four walks with eight strikeouts.

The Mets pieced together the rest, which included scarcely used Edwin Diaz pitching two innings for his 24th save in 26 chances.
