Castellanos is out of the lineup for Wednesday's game against the Giants.
Castellanos and Miguel Andujar shared the designated-hitter spot through the first five games, but neither player will be in the lineup Wednesday. Ramon Laureano will receive a day off from playing the outfield, but he'll stay in the starting nine at DH while Bryce Johnson takes his spot on defense. Castellanos has thus far gone 2-for-12 with a double and a walk, so he'll need to raise his production before solidifying an everyday role.
