Making his big league debut, McLean shut out the Seattle Mariners over 5 1/3 innings on Saturday afternoon at Citi Field in a 3-1 win, navigating a deep lineup with an array of spinning breaking pitches. It was an impressive outing for the rookie right-hander, but when manager Carlos Mendoza went out to the mound in the sixth, fans booed the move.

McLean joined Matt Harvey as the only pitchers in Mets history to earn a win, strike out eight or more and allow zero runs in their debut.
