Solano went 3-for-4 with a double, a run scored and two RBI in Thursday's Grapefruit League game against the Astros.
After spending last year in the Marlins' organization, Solano returned to the Nats in the offseason and will provide some depth at catcher at Triple-A. Injuries could allow him to see some big league action, but the 31-year-old can't be expected to make any kind of fantasy impact if he does.
