And Lindgren got him out.
Harper appeared in 414 games and logged more than 1,700 plate appearances before coming up against a pitcher his own age.
The Nats' star flew out to left field in his eighth-inning at-bat against Lindgren, who was selected by the Yankees in the second Round of the 2014 Draft out of Mississippi State. Wednesday was Lindgren's sixth Major League appearance.
