Tena was optioned to Triple-A Rochester after Sunday's 3-1 loss to Miami, Andrew Golden of The Washington Post reports.
EDGE Analysis
Tena earned a spot on the Nationals' Opening Day roster, but he has yet to find a groove this season, batting .248 with 12 doubles, two triples, 13 RBI, 18 runs scored and a stolen base over 137 at-bats in 44 games. The 24-year-old will now look to get back on track with Rochester in an attempt to potentially return to the major-league roster down the road this year.
