Walker went 1-for-4 with a solo home run in a 6-2 loss to the Mets on Sunday.
Walker took New York starter Tylor Megill 467-feet deep to left in the fourth inning to tie the game at 1-1 but wasn't able to produce in his other three at-bats. The 31-year-old now has exactly one hit in five consecutive contests, though the efforts haven't pushed Walker's average up much, as he's gone from .118 to .167.
