The echo off empty seats in left field carried across a mostly empty Coors Field Tuesday afternoon. When a line-drive home run travels 434 feet and hits off the tin of bleachers, the sound rings like a "ping."
Arizona's Phil Gosselin rocketed a three-run homer off Miguel Castro in the seventh inning that would have shushed a crowd if they'd been yelling.
The Diamondbacks stamped a homer-heavy 6-4 victory over the Rockies in the first game of a doubleheader and Colorado started its final month with a whisper.
Colorado and Arizona combined for five home runs, none shorter than 434 feet.
