There are times when a ball exits the park so suddenly, withsuch force, it leaves everyone in awe. A kid named Paul Goldschmidthit one of those shots at AT&T Park on Tuesday night,jump-starting Arizona's 6-1 win over the Giants , and it wasn't merely arandom moment in time. It was exactly why the Giants have a big problem on theirhands. The defending champs have no power, and we've reached the pointwhere it's safe to say they won't have power. Not in any significant way.Fans, writers and perhaps even the Giants themselves have downplayedthe Diamondbacks' chances to have any impact on the NationalLeague's Western Division race, but such thoughts are pure follyright now.
