Grichuk rejected an outright assignment from the Yankees on Friday and elected free agency.
The veteran outfielder was designated for assignment earlier this week after batting .194 (6-for-33) with 10 strikeouts in 16 games to begin the season. Grichuk posted a .674 OPS in 113 regular-season games between Arizona and Kansas City last season and will likely have to settle for another minor-league contract
