Seager, 21, batted third in only two of his 25 starts this season while compiling a .337/.425/.561 slash line for the Dodgers following his Sept. 3 call-up.
Seager also batted twice on three occasions, and cleanup once.
Hernandez had been the Dodgers’ preferred center fielder by the end of August, though both he and Pederson were alternating in center — against both lefties and righties — after Hernandez returned from a hamstring injury in September.
The Dodgers’ full lineup against Mets right-hander Jacob deGrom:
Carl Crawford LF
Howie Kendrick 2B
Corey Seager SS
Adrian Gonzalez 1B
Justin Turner 3B
Andre Ethier RF
A.J. Ellis C
Joc Pederson CF
Clayton Kershaw P
