Arraez is out of the lineup for Thursday's game against the Nationals.
The Padres are closing out their series in Washington with a day game after a night game, and the Nationals are bringing a lefty (Patrick Corbin) to the hill, so San Diego manager Mike Shildt likely decided that it was an opportune time to give the lefty-hitting Arraez a breather. Unless he's used off the bench, Arraez will put his six-game hitting streak on hold and will cede the designated-hitter spot to Manny Machado on Thursday.
