Jaylin Davis recently met ''The Say Hey Kid'' and later learned from manager Bruce Bochy that Hall of Famer Willie Mays had his own early struggles at the plate. Davis finally hit his first career home run Wednesday, a timely drive to end the game with one out in the ninth that sent the San Francisco Giants past the Colorado Rockies 2-1 when nobody wanted another long night. ''We didn't want to go extra innings tonight,'' Davis said, grinning.
