Nevertheless, McLean instantly proved he belonged with 5 2/3 innings of shutout ball and eight strikeouts against a solid Mariners lineup. He made their hitters look foolish over and over again mostly with his sweeper and curveball.

Nolan McLean had just finished up his bullpen session on Wednesday when Triple-A Syracuse pitching coach A.J. Sager had some news to share.

The first pitch was a ball. The second, Rodríguez lined toward McLean, who fielded the ball on one hop behind his back, and then had the presence of mind to throw to second for a chance at a double-play.

Nolan McLean is as advertised. In fact, in his MLB debut, he had a start only matched by one of the most-hyped young pitchers in Mets history. McLean went 5.1 innings on Saturday and struck out eight without allowing a run.
