The Athletics recalled Allen from Triple-A Las Vegas on Wednesday.
Allen earned the promotion after putting up a 1.136 OPS with five home runs and seven stolen bases in August. He has managed a lowly .210/.256/.284 batting line in parts of three seasons with the Athletics, and with Jacob Wilson, Zack Gelof and likely Max Schuemann ahead of him in the pecking order in the infield, Allen may be in store for sparse playing time over the final month of the campaign.
