White went 0-for-2 with a walk in Sunday's 5-2 loss to the Nationals.
White made his major-league debut in Friday's series opener, going 1-for-4 with a double. After being held out of the lineup for Saturday's 15-1 win, White re-entered the starting nine at first base Sunday and went hitless but drew his first major-league walk in the bottom of the seventh inning. White will likely continue to see work at both first base and third base in the absence of Nick Kurtz (thumb) and Zack Gelof (knee).
