Arraez will sit against lefty Robbie Ray and the Mariners on Friday.
Arraez has a career .662 OPS against southpaws compared to an .814 OPS against right-handers. His exact role this season remains to be seen, but it's likely he sits frequently against lefties while starting around the diamond against righties. Gio Urshela will start at third base, Arraez's primary position last year, on this occasion.
