Double-A Harrisburg (Nationals) outfielder Justin Maxwell has been placed on the seven-day disabled list.

Through 43 games, Maxwell is batting .233/.367/.459 in 180 plate appearances. Maxwell, who ranked as the No. 8 prospect and the No. 3 positional prospect in the system entering the season, had missed a few games and was day-to-day with a wrist injury. He returned to the lineup on Sunday and Monday, going 0-for-7 with two walks, but did not play yesterday.
