Altherr hit a solo home run as a pinch hitter in a loss to the Tigers on Friday.
Stepping to the plate in the sixth inning with the score tied 6-6, Altherr took Buck Farmer deep for his first homer of the year and only his second hit in 32 plate appearances. Altherr's stay with the Mets is likely to be a brief one -- Michael Conforto (concussion) could be close to a return from the injured list, and the organization just signed Matt Kemp to a minor-league deal.
