Peterson replaced Brandon Phillips (groin) at second base in the second inning of Wednesday's win over the Mets, going 2-for-5 with a double and an RBI.
Phillips isn't expected to miss much time, but Peterson should get at least one start at second base Thursday while the veteran is recuperating. Assuming he does get the nod at the keystone over Emilio Bonifacio, Peterson could be a useful DFS punt play Thursday despite his soft .211/.302/.316 slash line through 43 plate appearances this season.
