The Nationals selected Winker to the major-league roster Sunday.
The 30-year-old joined the Nationals as a non-roster invitee in February and earned a place on the Opening Day roster with a .932 OPS in 15 Grapefruit League games. Winker posted a .567 OPS with Milwaukee last season but was limited to 61 games while returning from neck and knee surgeries, and he'll likely need to be more productive in 2024 in order to stick around in Washington.
