Manager Pete Mackanin said Neris would fill in as closer for Jeanmar Gomez while he is on the paternity list, Evan Webeck of MLB.com reports.
Gomez is expected to return to the Phillies on Thursday even though he is eligible to be away from the team until Saturday. Neris was used in the ninth inning Wednesday and tossed a scoreless inning to preserve a 4-4 tie in a game the Phillies would go on to win in extra innings.
