After recording 852 wins at the Kingdome — plus 4 postseason victories— the Mariners picked up their first win in their new ballpark on July 17, 1999 against the Padres.
It took the Mariners three tries to secure their first win in the Kingdome, and it also took three attempts to earn their first “W” across the street.
David Bell, Ken Griffey Jr. and Alex Rodriguez each collected 2 hits, but it was Raúl Ibañez who delivered the big hit, a 7th-inning grand slam — the first in T-Mobile Park history — to stake the Mariners to a 9–1 lead.
