Grichuk will serve as Arizona's designated hitter and No. 2 batter in Thursday's game against the Mets.
Grichuk will crack the lineup for the second time in the series, with both starting assignments coming while the Mets have sent left-handers to the mound. The 33-year-old continues to fill a short-side platoon role for the Diamondbacks, either as a replacement at DH for Joc Pederson or in the outfield for Corbin Carroll or Jake McCarthy when Arizona faces southpaws.
