It probably sounded good at the time. A group of softballlegends would come to AT&T Park and stage a power-hitting showat dusk, putting everyone in a festive mood for the Cubs-Giants game to follow. By the time the Long Haul Bombers finished their exhibitionTuesday night, the Giants wished they'd never signedthe papers. It wasn't just a prelude to the team's latest disgrace,a 5-2 loss. It seemed almost insulting to a bunch of major-leaguerswho can't go deep to save their lives.
