Hernaiz will be up with the Athletics for the third time this season after slashing .237/.318/.288 with one home run, three stolen bases, seven RBI and 12 runs in 134 plate appearances between the prior two stints. The Athletics placed Tyler Soderstrom (hip) on the 10-day injured list to clear a spot on the active roster for Hernaiz, who is likely to serve in a depth role in the infield and is expected to receive most of his playing time versus left-handed pitching.

Both Hernaiz and Joey Meneses will head down to Triple-A in moves that correspond with the Athletics selecting Brian Serven's contract from Las Vegas and reinstating Zack Gelof (hand) from the 10-day injured list. Hernaiz did not see major-league action after being called up by the Athletics this past Monday but will see more playing time in Triple-A, where he has a .714 OPS with two steals and six RBI over 82 plate appearances.
