Melendez is out of the lineup for Wednesday's game against the Cardinals.
Melendez had started in four of the team's previous five matchups with right-handed pitchers, but the Mets won't have room for him in the lineup Wednesday while Francisco Alvarez handles designated-hitter duties in his second game back from the IL. Since the start of May, Melendez has posted a weak .533 OPS, so he likely still has more work to do in order to strengthen his grasp on a regular lineup sot.
