With the trade deadline gradually approaching, teams have contacted the A's about a possible move for Ben Zobrist.
The Nationals are the latest team to inquire about the utility player, but talks are only preliminary, according to a Fox Sports report.
Zobrist was sidelined for a month earlier this season because of a meniscus tear in his left knee.
The 34-year-old is batting .222 with 2 HR and 14 RBI in 23 games for the Athletics.
The Cubs have also been linked to Zobrist.
