DENVER To find the last time the Giants hit four home runs in aninning, you'd have to go back to the Kennedy administration. Your time machine would let you out on Aug. 23, 1961, you'd beat old Crosley Field in Cincinnati and you would've seen OrlandoCepeda, Willie Mays, Jim Davenport and John Orsino find the seatsin the ninth inning. The Giants do not have a time machine.But they continue to play like there is sand in their hourglass.They went deep four times in an eight-run fourth inning, PabloSandoval bookended the sustained rally with a pair of homers, andthe NL's worst offense polished off a six-pack of home runs in a12-5 victory over the woeful Colorado Rockies.
