Acuna is out of the lineup for Thursday's game against the Diamondbacks.
Jeff McNeil has mostly been playing in the outfield since returning from the injured list a week ago, but he'll return to his more natural spot at second base Thursday, which leaves no room in the lineup for Acuna. The 23-year-old had occupied the keystone for each of the Mets' last five games, going 6-for-20 with two runs, two RBI and a stolen base.
