Griffin (forearm) is serving as the designated hitter and batting sixth against the Twins on Friday, Danny Demilio of PittsburghBaseballNow.com reports.
Per Colin Beazley of the Pittsburgh Post-Gazette, Griffin has not been cleared to throw due to a right forearm flexor strain but has been given the green light to hit. Marcell Ozuna will see a dip in playing time while Griffin gets rep at DH, and Jared Triolo will see more starts at shortstop as well.
