Tena (thumb) is out of the lineup for Wednesday's game against the Orioles, Mark Zuckerman of MASNSports.com reports.
Tena will sit out again while he recovers from a fingernail issue on his right thumb, which stems from being struck by a groundball in Sunday's loss to the Angels. Ildemaro Vargas will fill in at third base for Tena, who can be viewed as day-to-day heading into the Nationals' four-game series with the Phillies that begins Thursday.
