Gillaspie was designated for assignment Wednesday but did not garner the interest of any other big-league clubs. He'll likely receive regular playing time with Sacramento moving forward.

The move was inevitable for the Giants' 2016 postseason hero after he struggled mightily in a limited role this year (.163/.218/.288 in 87 plate appearances). Gillaspie figures to reject a move to the minors in hopes of latching on as a bench bat with a contender. Ryder Jones was called up to take his spot on the roster and in the lineup.

Since southpaw Sean Manaea is starting on the mound for Oakland, Gillaspie will cede Tuesday's start to avoid the lefty-on-lefty matchup. Jae-Gyun Hwang will man the hot corner in his stead.

Despite knocking a pinch-hit home run in Sunday's loss to the Dodgers, Gillaspie will head to the bench for a third straight contest. He's slashing just .171/.229/.303 in 83 plate appearances this season, so he is far from a desirable option at third base. Jae-Gyun Hwang will draw another start at the hot corner in his place.
