The Washington Nationals are hosting a blood drive in partnership with Inova Blood Donor Services until 5 p.m. Saturday -- but you must have made an appointment to participate.
Blood donations must be made by appointment only. Walk-ins can stop by the park beginning at 3 p.m., but there is no guarantee that everyone will be seen.
Donors will receive two tickets to a future Nationals game as well as an exclusive Nationals T-shirt and opportunities to win autographed memorabilia and a behind-the-scenes tour of the park.
The blood drive will continue until 5 p.m. Saturday.
