Robles (hamstring) will start in center field and bat leadoff in Sunday's Grapefruit League game against the Twins.
The 26-year-old made an early exit from Saturday's contest due to a hamstring issue, but his presence in the lineup a day later indicates it wasn't a serious concern. Robles is expected to open the season as Washington's primary center fielder but may need a strong start to retain the starting job.
